Oldsmobile Intrigue Starting/Stalling

edited April 2018 in Oldsmobile
I have a 2000 oldsmobile intrigue that i recently replaced the crankshaft sensor on due to the b circuit failing. I now turn the key and sometimes have to cycle it several times to get the motor to start. The motor will not crank at all while i am cycling the ignition. So if anyone has any ideas let me know. I also get a code now for the A circuit on the crankshaft sensor and a camshaft b circuit sensor code. not sure if it has anything to do with replacing the crankshaft sensor.

    The engine taking a while to start could signal a problem with the fuel pressure regulator.

    What are the actual code numbers you are getting?

    my car starts no problem when the engine is cold or if it's been shut off and restarted within a few minutes, but if i shut the engine off and restart let's say after 30 minutes it takes several seconds for it to start. i actually need to press on the accelerator a bit for it to start. this proves to me that there is a fuel flow problem. i changed the fuel pump, fuel pressure regulator, spark plugs, cables, crank shaft sensor, cleaned the injectors and also the fuel railling. sometimes this problem goes away for several weeks and then comes back. please if anyone has addvice i would appreciate it, thanks!!

    i see everything listed there except a fuel filter, which is what your problem sounds like. try a filter they are cheap, around 10 bucks, it should be mounted along the frame rail under the car on the drivers side, if not there look in the engine compartment or possibly near the gas tank. hope that fixes your problem.
  • dtownfbdtownfb Posts: 2,918
    Considering he has changed everything else, I would try the fuel filter (which is located along the driver side in front of the rear tire). I don't think that is the issue. Instead of changing parts, you need to get readings on the fuel pressure to confirm it is a fuel flow problem.

    The Intrigue has some "interesting" electrical and ignition issues that could cause the same problem. But he needs to confirm the fuel pressures first.

    Also knowing what engine he has will help.
  • every so often i have probs with the car not turning over. the security light goes on can hear the gas pump running...yet nothing else happens. after waiting (any where from a few minutes to a few hours(usually 15-30 min) i will try again and it usually then turns right over.the guide say very little in dealing with the " security-pass" shop told me poss ibly the ign. key core and matching olds pass key etc might need to be replaced? ($385)....any ideas? it is a 98, 3.8....otherwise a good ride
  • dtownfbdtownfb Posts: 2,918
    It is most likely the ignition switch that is the problem. I would try cleaning the ignition switch first (spray WD-40 into the key hole). I bet if you did Google search on Intrigue ignition switch, you'd probably find websites that give detailed instruction on how to replace it yourself. From what I understand, it is not very hard.

    Update: I found the location of the directions to change the ignition switch. hope this helps:

    I have 99, 3.8 that is doing the same thing. Have you resolved your problem yet? The thing that makes no sense at all is I can go 3 or 4 days and it cranks right up..then 3 or 4 days it wont crank or do anything when I turn the key.

    Does your car also stall while driving?

    I have had the crank shaft sensor replaced, new starter, battery, fuel filter.

    jacksonpg15...just curious if you have resolved your problem yet?
  • jberjber Posts: 1
    I have a 99, 107K, with the same situation. sometimes it has no problems starting, other times it refuses to turn over. doesnt matter hot or cold, if I just drove it, or its been sitting... the wierd thing is that I can usually get it to start by closing the drivers door while I have the key in the cranking position, or sometimes by putting the car in neutral. sometimes it takes both, sometimes nothing works except to keep trying. I get the same codes camshaft and crankshaft sensor., and the SES light is intermittent. Do I Replace the sensors? -saw the post about the camshaft sens., but how difficult is the crankshaft sensor? Any help would be appreciated-

  • dtownfbdtownfb Posts: 2,918
    Since both codes are showing, I would take it to a mechanic to have both sensors replaced. Not sure how easy or hard it is for a DIY to do the work. Try a Google search.

    I have a '99 Intrigue with the 3.5 L engine - when I first start it up, it starts okay, but after a couple minutes of driving, the engine just dies. I can start the engine again easily enough, and once it warms up, I don't have this problem again, but obviously I want to find a solution. BTW, about 3,000 miles ago I had the fuel filter replaced as well as the spark plugs and the plug boots.
    Any ideas would be very welcome.

    my battery died and i had a jump but that didnt work then i charged it and that dot work i have full power to my lights and interior can some one help
  • indrgbindrgb Posts: 115
    Remove the negaive then positve battery terminals. Check for corrosion at the positive battery connection and wire terminal. Also look for any other problems on both positive and negative. Sometimes corrosion will allow small currents to flow from the battery, but not large current required for starting.
  • My only issue with starting is that sometimes when the engine is warm, it will stall out once or twice before it finally catches. The car only has 91,000 miles, and is pretty clean, inside and out. If I press down on the gas pedal before I turn the key, I know it will stay running, but it revs way up before it settles down. You can see the needle jump on the tach, then drop to about 500 RPM's, them climb back up and stay at about 750. If the engine is cold, it will go right to idle speed. This is more of a nuisance than a problem, I suspect that it is possibly a faulty TPS. Sound familiar to anyone ?

    I need to replace the CKP on my 2001 oldsmobile intrigue. I found instructions for replacement on the 2002 intrigue here

    Does anyone know if its the exact same procedure for the 2001? Also, does anyone know a way to measure the bolt tightness...cheaply? I would like to thank everyone here for helping me so far. I have read many posts since joining last year.

    I don't have the money for labor but I found the part cheaply at I am not a genius under the hood but I am going to try to change it myself. I'll report back and let everyone know how it goes.
  • dtownfbdtownfb Posts: 2,918
    I think it is safe to assume that the procedure is the same. GM had already made the decision to kill Oldsmobile. There are very few changes made in Intrigues built after 2000.

    You can get a torque wrench at Sears (or KMart) fairly cheap. Or try a place like Harbor Freight. Some auto parts stores will loan you tools as well.

    I replaced the crankshaft position sensor!!! That's a big accomplishment for me because I had never even changed a flat tire before.

    After I replaced the CPS, I tried to start the car and nothing!!! It wouldn't even start to crank. I don't know if its the battery or the starter or something else. The radio and all of the console lights work, so I guess its not the battery. I hadn't even started my car for 5-6 months before replacing the CPS. The car would crank before my repair.

    Before I tell everyone how to change the CPS, I would like to make sure that I did it correctly.

    Update, I disconnected the wrong battery terminal before starting. I disconnected the negative cable. Could this be why my car won't crank over now, or is it the battery?
  • coonhoundcoonhound Posts: 174
    I have the exact same problem on a 2000 with 94000 miles. I am hoping that you found the problem and can enlighten me. I am leaning toward the fuel pressure regulator. I hear the pump running for 5 seconds or so when engine is warm, but nothing with cold start.
  • dio__2dio__2 Posts: 6
    I replaced the crankshaft position sensor and shorted out a fuse when I did it. I got a new fuse and the car cranked and started up but before I got out of the parking lot it stopped again :( The car just stops, buzzes and all the warning lights go on. Then it won't start back up again for a while. I'm hoping that there is nothing severely wrong with the car. Any ideas? I've heard that it could be the fuel pressure regulator or the ignition control module but I have no idea it wasn't giving any codes. My friend thinks that its some sort of "floating short".
  • I haven't done anything with it yet, it is not at the critical stage, just the occasional nuisance stage. My wife had a 2000 Alero ( 3.4 ) and that FPR sprang a leak, that malfunction was obvious. Changing it wasn't hard or terribly expensive, but of course the 3.5 is a completely different engine. Just like changing the oil filter, this could wind up being a whole different experience.I had a '98 Intrigue ( 3800 Type 2 ), and that never had this problem, even with about 123,000 miles on it. Unfortunately, that one was demolished last summer, but it saved my kids' lives in a rear end collision with a Mack dump truck. My daughter was driving, doing 30, the truck hit them doing about 50. They all walked away without a scratch.

    check out the connectors at the battery. Make sure the connection is clean and secure.
  • This is not an electrical issue, something occasionally interrupts the fuel flow during startup. During these episodes, when the engine does finally start (usually after one or two more tries ) it revs way up and then drops low and then comes up to normal RPM's. It acts like the dam just broke and the gas finally rushes in. Engine temperature seems to have some effect, the colder it is, the easier it starts. Could be the rubber diaphragm in the FPS.
  • dtownfbdtownfb Posts: 2,918
    I had a hard time following your problem until I realized you used two different user names and two different posts....I think. Either way, if you haven't started it in 5-6 months, I would try one of those fuel line additives that is designed to get the water out. Also you may consider replacing the fuel filter (by the driver's side passenger door). Those are pretty cheap and you should be able to do the fuel filter yourself (start the car; pull the fuel pump fuse and have at it.) esp. if you replaced the crankshaft sensor yourself.

    Also if you turn the key to the "on" position you should hear the fuel pump humming for 2-3 seconds. This is normally a quick way to see if the fuel pump is working. To check the fuel pressure regulator, you need a pressure gage for the fuel line. Those aren't too expensive. You should be able to do a google search on that procedure.

    dennis1957 is someone else with a similar but not the same problem. I only posted the stuff under this screen name. My car will start up when its cold but it will cut off when you get moving, the dash will buzz and the check engine, service vehicle, anti-lock and brakes lights are on. Maybe its electrical maybe its not. The car is most likely to stall when it accelerates, decelerates, or when I'm coming out of the parking lot (the front end is tilted down).

    Warm engine starting problems. I just ordered up a Borg Warner fuel pressure regulator for $41.00 it will be at the parts house in a couple of hours. A post on another site mentioned that the fuel rail must be lifted up to allow room to remove the regulator. I don't know if this completely pulls the rail up enough to disengage the O rings or not. The regulator just has a clip to hold it in place and reportedly it only took about 20 minutes to replace.
  • coonhoundcoonhound Posts: 174
    FPR update. I replaced the FPR and I notice that the engine is smoother running. It's only about a 20 minute job. The injector rail does not have to be moved to R&R the regulator. BW did not include the mounting clip as the oem unit would have, but I doubt that the clip is worth $80.00 or so difference in price. Just required a little motor oil on the O-rings and position the vacuum tube pointing in the direction as removed or the vacuum line will be too short. Located at the rear of the engine, drivers side at the end of the fuel rail.

    Piece of cake.

    You didn't mention if you have a set code or check engine soon light when the car is running. If so take it to Auto Zone and have them check the code. The ignition switch is another known gremlin. Mine would just die going down the road before I spent $300.00, at the dealer, to replace the switch.

    I have had so many problems with the intrigue that I bought an OBDII code reader. But this can be a double edged sword. Engine failed to crank at all and I would get both crankshaft and camshaft position codes. Well! if the engine isn't turning over then they have no feed back. I replaced the camshaft sensor. Wound up having it towed to the dealer and spent $300.00 for a starter. In the days before hi tech I would have had someone rap the starter with a hammer. But???? :cry:
  • dtownfbdtownfb Posts: 2,918
    Sorry dio_2. Dennis1957 responded to my initial answer to your post which caused me confusion. Any way.... Since you haven't started it in a while, check the batterry with a voltmeter. On another forum, a low battery caused the light on the dash to "go crazy". Also, you may want to check the gas and fuel filter. If it has been sitting that long, it could be causing some problems. Try one of those additives that gets rid of the water in the fuel. I would also check (and clean) the air filter and throttle body. Those are simple since you already tackled the crankshaft.

    Like coonhound mentioned, the ignition switch could also be the problem.
