    Crank Position Sensors.
  • Would this also cause my computer to restart???

    What do you mean 'computer restart'?
  • When I start my car back up, everything electric resets............like my clock, trip mileage ect.

    Well, that little piece of info puts a different face on it.

    Looks like you have a total electrical failure. Which could be a very discharged battery - except the car would not restart.

    Sounds more like there is a battery cable failure - an intermedent open in one of the cables.

    Clean the cable attachments. Retighten them down securely. See if you can get to the ground cable where it grounds to the motor (usually) and see that this ground is clean and tight. Look closely at the cable ends at the battery. Acid could have gotten down inside the cables, under the insulation, and literally eatten the cables apart.

    Or, some kind of bad failure in the main fuse box. If the thing comes and goes, it's going to be tough to find the problem until it totally fails.

    Anyway, it sounds electrical. Where, exactly, ????

    Hi I have a 2003 Cadillac Deville Dts. and since Nov 2007 it has been stalling. It seems to happend 1 evey three-four weeks. Then if i leave it off for a while it will turn back on wiht no problem. Or if I turn it off open all doors and let itslef reset it will start. It is soooo weird. I have taken it to Cadillac and they don't know whats wrong. I have already changed out the Cam sensors and and the torque converter but it is still happening. The guys at the dealer our clueless and say the car is perfect. NO IT'S NOT if that was the case it wouldnt turn off .. Please someone HELP !!!! I have a baby and I am scared this might happen while i'm driving. Luckily so far its only when I get in my car and turn it on.

    Oh yeah and now it's leaking oil ..AHHHHH !!
    :cry: I've only had the car 1 1/2 and it has :mad: 75000 FYI. :cry:
  • I have a deville, it wont start, i have checked into many possibilities, like checking for spark, (there is) New fuel pump, filter, and strainer, put new alternator in, new battary, so now i am looking into the fuel being the issue at hand. There is fuel going into the fuel rails, when they are compressed fuel is shooting out, so where it goes after there may be the problem? That i dont know. When there is fuel put directly into the throttle body, it will start up, then die when there is no more fuel in there, but when turning it over i get nothing along with that, we took the throttle body off, and under there are two pipe like things that go strait up under there, one of them are clean and have no grime or anything, the other however has sludge like stuff inside it,and when i attempt to start it that stuff sprays out, I dont know much about cars so im hoping someone will come across this and have an answer, I have ran outta things that people tell me it could be that its not...so im at a stand still and really would appreciate some advice...besides getting rid of it, ive put too much into it to want to do that. Please someone help!!!

    I have a 1998 Cadillac Deville and for the last two months it has been stalling at stop signs whenever it is raining. Garage says its wiring but to hard to track. Any Ideas?

    Crank Position Sensors. There are two of them, replace them both. If it truly is water related, the connectors for the sensors might have a problem.

    Once the car is started, there is no problem with that. As I'm driving the car, every once in a while it would just stall out. I'll pull off the road and restart it with no problem. It wont really happen again until the next time I drive it. There is no check engine light or anything. I tried to get a diagnostics but couldn't because the check engine light wasn't on. Other than that, everything works as it should. Can anyone help me with this? :confuse:

    Gee, didn't you read the message just above yours?

  • I didn't, but thank you for the advice. I'll look into the price. I'm not a mechanic so do you think it will be better to have dealer do the work or buy the parts and take to my mechanic?
  • bolivarbolivar Posts: 2,316
    I'm a cheep SOB, but that is something I've never had the guts to do - buy parts and ask a shop to put them on. You are basically asking him to reduce the price on the job by about 10% or more, which is his discount on the part when he buys it and charges you retail.
  • well i have changed the Crank Position Sensors. Not to mention a bunch of other things and my car still keeps stalling out. One minute its fine the next it doesnt feel like staying on. It seems like the fuel is not getting to the car. I've taken it to Cadillac but they can't find anything b/c the check engine light is not on. What else could it be ?
  • I've had a 97 Deville now for 4 years. When I first got it (had 50,000 miles on it), it stalled when I was decelerating.....say from 40 MPH down to 20 or 10 MPH....I replaced the crank shaft position sensors, fuel pressure regulator, fuel filter, etc. Turned out to be the EGR valve....(it was just not functioning properly and choking off the engine). I have had no decelerating stall outs since then (going on 3 years and I'm up to 100,000 Miles).....but like most 10 year old Devilles new problems have emerged over the last couple of months (it's been a relatively quiet 3 years of driving though since so I can't totally complain).
  • So my current issue with my 97 Deville which only occurs when it is raining (okay so I'm instantly thinking electrical system). The vehicle stalls out when I am stopped at a light...will restart right back up....and once in a while if I'm going really slow making a turn say under 5 MPH it will stall.....it definitely has to be raining outside and it has to be in drive (if I put it in park at the light it will not stall). I saw the post about checking the battery cable, grounds, and connections (all great ideas and I'm currently doing this....I think it might be the alternator connection). Was wondering if the 98 Deville that had a similar problem found anything. I have had a weird occurence which may be related (about 3 times now when I've started the car the gas cover solenoid has activated....almost like the car has lost power and the computer gets a quick surge...I believe I can replicate this by removing power from the battery and quickly reconnecting (again would point to the power / ground cables) With this the radio goes to a channel I haven't programed, but the other items don't reset (trip odometer, gas mileage etc.) The vehicle truly is in great shape and this is not a huge issue, but would be good to correct. Any thoughts or similar problems out there????
  • I have a 1998 Deville and the driver’s window stopped working. I can’t locate the fuse, the books I have talks about the fuse and relay but they don’t tell you were they are located. Is there a trick to getting the door panels off?
  • bolivarbolivar Posts: 2,316
    The fuses and relays are not inside the door panels, but are in the fuse boxes. Under the hood and inside the trunk. You have to take out the carpet trim and the fuses are on the left front of the trunk I think.

    Removing door panel, if like my 97 - there is a screw behind the lower rear lights that turn on when the door is opened. You have to pull the lights off and there is a screw. Then pry up the panel at the front that has all the power window buttons (I think, it's been a while since I did this, it might be the seat control panel.) You must pry the panel up, then there is another large screw that can be reached. Then, there is the little triangle shaped trim piece at the front top of the panel. There is a push-in panel pin there, you gently pry around this piece until it pulls out. There are NOT push-pins all around the edge of the panel - it is retained by screws, this one pin at the top front, and it then have J hooked shaped connectors on the panel that push down into U shaped connectors in the inner door.

    So, basically, when you have the screws out and the one pin out, you just pull the panel straight up and it's loose. There are all kind of electrical connectors still attached. The lights, the window controls, the speaker wires, etc, etc. And, you probably have a side AIR BAG! Before starting any of this DISCONNECT THE BATTERY! Disconnect the air bag connections from the panel. If you blow an air bag, don't blame me!

    What you are trying to get to is the window motor, which is probably failed. Pull the power connector off the motor. Put a volt meter into the two wires of the connector. Reconnect the battery. Push the window button up, you should have 12+ or - volts. Push the window button down, you shoud have 12- or + volts (the reverse of what you get the other time). If you get this, the wiring and the switch and the fuse, etc are all ok. If not, start working on getting power there. If you have the correct voltages, the motor has failed.

    Put a couple of strips of duct tape up the window and onto the top of the door frame. This will keep the window from falling. There are 3 bolts holding the motor in, it's real easy to remove. After bolts out, you might have to wiggle it around a little. Take the motor to any auto parts house. Check carefully that the motor sold to you is identical to the old one. At Autozone, their part numbers are messed up, I got a right hand one when I needed the left hand one, so, take the old one in. It should be about $70 or so.

    Buckle it back up. Your are done. The worse part of the job is getting the door panel off a Cadillac. The motors are all bolted in and easy to remove.
  • Well I took the car to the dealer and was told that the crank sensors were good and that the ERG was faulty. Had it changed and that still didn't fix the problem. Afterwards, the throttlebody was cleaned and they said that should do the trick, but once again it did nothing. Now I'm being told that the IAC is most likely the problem. Is there anyone who can really help me? Some of the DTC codes are: PCM P0603, IPC B1552, ACM B1341, TCS C1255, PZM B1552/1558, and MMM B2144. Most these didn't show until I disconnected the negative cable from the battery. Also they all are history codes and not current. Please help, I'm at a loss:( :confuse:
  • Also, can someone explain the body control module on a 1998 deville, and where it's located? Thanks! :confuse:
  • on the stalling on the 98, I was told to change the Idle Air control valve, but I really don't trust the dealer being that they told me it was the EGR valve and 500.00 later the problem was still there. Then they said that EGR just had to go through a reset phase which is not true. Also the throttle body was cleaned out and the problem is still there. I'm really tired of this problem and wish I could just get this resolved. Good luck on your problem and hope you find it.
  • no other answers on stalling Deville besides Crank Position Sensors?????????? :confuse:
  • Well went out on a limb and changed the IAC valve and it seemed to have fixed the problem of the stalling. the valve is two screws and right on the side of the throttle body on top. Real quick and easy fix plus no maintenance cost on your own labor. So if there were a lot of things changed including the CPS's, change that valve and you should see the problem disappear. Remember to disconnect the neg cable from the battery for about 30 sec to reset the ECM. Good luck out there! :)

    I have a 2000 deville.When turning key no power to starter. Checked for trouble codes, can not connect with pcm. all fuses are good
  • I have a 1998 4 door cadillac deville with Power Windows. There is a contol pannel with 4 buttons on the driveres door to control each window. I recently rolled my drivers side window down and now , when i press the button to roll it up, the window will not roll up as if it is not getting any power. The other three are working fine and getting power but not the drivers door. has this happened to anyone else and does anyone know what i need to do to fix it? I first thought that it might be a fuse, but i assume if its a bad fuse then the other three would not be getting power either??
  • bolivarbolivar Posts: 2,316
    The motor probably died.
  • This like new vehicle has just 55,000 miles and is just used once a week. For some reason while driving, the gas pedal becomes hard, then the brakes, then it will stall. after complete turn off. It will restart and not occur for another month.

    any help will be appreciated
