basic tune up and check the fuel pressure.In the air filter box when you replace the filter,you may even find that chipmunks or field mice have made a home there.
After all this see what you find. What did you do to get it started? Make sure the
fuel tank is full of fresh fuel. Did the previous owner change the fuel pump? There are mistakes that people make when they do this.Do this and see what happens.
Fuel pressure should be between 54 and 61psi.
Thanks again I will let you know how I make out
Other than that, you might check the fuel pressure regulator. If it's bad, it will cause hard starts when the car's been sitting. You can pull the vacuum line off the fuel pressure regulator and if there's any gas in there, it needs replacing.
I dont want to look stupid here but where is the press reg?
If you ruled out bad or dirty sensors and are driving your self nuts, a good bleeding, and checking calipers would be a good place to start.
I used a vacuum hand pump to bleed them. $30 well spent once everything was bleeder screw sealed properly with a little teflon tape.
Thank you Cardoc50 for the advice
1995 up has changes made to the wiring, fuel system,brakes and a lot more. That
makes things hard to diagnose. Every year they change something. That my
friends is hard even for a mechanic to keep up with. So be patient if it takes me
a while to figure a problem out. I will do my best to help anyone.
Thanks dp2226
If the instrument panel dimmer / dome light onj-off switch is in the dome light off position and the dome light remains on......you may need a new switch. Std. Motor Productrs DS961...$34.79
OR:
Replacy the Courtesy Light Relay. AC Delco D1786C...$8.11
I reached over and felt the instrument light dimmer - dome light on-off switch and the thumb wheel was still in the 'dome light on" position. That happens when you turn on the dome light and forget to turn it off.
The Deltran Battery Tender can detect any kind of battery drain...dome light left on or a shorted power door lock relay.That also happend to my S10 Blazer and completely discharged the battery in two days. After I installed a new power door lock relay and a new AC Delco battery, I purchased and now regularily use a Deltran Battery Tender. I use it not only to keep the battery fully charged but also to monitor the electrical system..
Those battery tenders are useful for warning you of an excessive battery drain. Normal battery drain on most GM vehicles is about 8 to 10 ma (clock, sensors, ECM, radio, relays, etc.) but a battery drain lthat small will not cause a battery to discharge or cause a battery tender to be in constant "charge" mode. However, if the battery drain is excessive, about 50 ma or more, the battery tender will go into constant charge mode illuminating the charge light, which indicates there is a electrical problem somewhere.
earlier years. If so,there is a spring on the foot pedal unit which when disengaged lets the pedal come back up. Yours is not locking when pushed meaning the teeth are :shades: not interlocking. You can remove the whole unit by removing the cable from the latch and a couple bolts holds the pedal assembly on. After removal,you can visually see what the problem is ie...bent pedal assembly or related parts. Also,
the release cable may need lubricated or the unit itself may need lubrication.After
you get into it you should be able to diagnose the problem. The worse thing that could happen is you may have to get a whole assembly from a salvage yard. I believe jflemmons is probably right when it comes to your dash problems.If not ,he is definately headed into the right area.

hope others will read our messages before they waste money on a aftermarket pump.Mine is a 97 Jimmy. There is another thing that needs to be noted to all do it your selfers... Before dropping the tank all the way, make sure the emmision hose is disconnected from the front of the tank. If the hose connector breaks off and the hose cannot be reconnected, it won't let any pressure build up in the tank and the
purge solinoid will not work making that part of the emission control system useless. After 7lbs of pressure builds up in the tank, the purge solinoid works. It does cause problems that a normal person just won't figure out. I did this on a 98 Blazer my Dad had.GM made these things different just about every year.Good job

your negative battery cable is not making contact either at the battery or the engine block. While the jumpers are hooked up you are useing the other vehicles ground and it will run until you unhook them. The battery cables can look good but be bad.They were bad about corroding bad inside of the insulation. I would have guessed the altinator first also. And possibly a grounded out battery too. Right now all that comes to mind is the ground cable since you have the new alt and batt. You should also check the ground strap from the engine to the firewall. :sick:
My dad had a problem on his Town and Country that was covered under a recall issued a couple of years before he got the van. Years later, the problem occured and the repair was covered. Safety issues under recall may not have an expiration date.
96 and 97, or is that 98 and 97 that is the special years for an elite canister? The fuel pump, gage indicator, and sock all come in one "inseparable" piece. There are many applications that come like this now, but buyers have to make sure that the fuel pump in the purchased canister is specific to their engine specifications. Do not let the parts guy sell you a canister for a 2.2 that looks the same, that you need for a 4.3. It will not supply the larger engine with enough fuel and will cause delays in shifting, hard starts and full throttle hesitation. Sometimes the manufacture messes things up in the right marriage of these components. Good observation Cardoc50. Great insight and expertise. We appreciate you!
message. It's a good chance the multi-function switch is bad. I had to change mine twice,(I got one out of a Blazer at the local scrapyard) after a couple years I had to replace it again.My Dads Blazer did the same thing. We were able to get new aftermarket ones off of e-bay. Around $100.00 I believe.
If your Blazer has a cruise control that does not work, it is likely the MF switch is bad. You must remove the old MF switch lever and fish the cruise control wire down through the steering collumn and connect it to the cruise control connector under the dash. You can cut and use the old cruise control lead to pull in the new lead or use a stiff wire as a fish line and pull in the new cruise controil lead. .
he needed a new multifunction switch because his rear lamps were not working properly. The same problem me and a thousand others had. I am a retired GM Ford
mechanic with of course all the ASE certificates that I had to take long tests for.
When I worked for a General Motors Shop we got TSB's from GM telling us to eplace that switch when we had a Blazer or Jimmy in for a number of other recalls.
There were many TSB's(the owner never knows about) on those vehicles.Over 42! I don't know how you can replace the cruise lever alone. If you could it would not fix the light problem. You do
not have to remove the steering wheel to change it.The switch comes as a whole unit and can be replaced in about 20 to 30 minutes.If he has cruise problems too,
great it would fix that too.If I'm not too late, please don't try to put a lever on the MF
switch and by all means Don't cut your wiring. .All wiring is made to snap together
with GM factory connectors.Sorry Duntov if I stepped on any toes.(switch not lever)
energy ignition parts in Summit racing and Jeggs also. I could not find what I was
looking for because the factory distributor only has a camshaft position sensor in it. As for timing, there are two crankshaft position sensors one on each side of the harmonic balancer.Of course these 3 sensors tell the ECM when to change ignition
timing. As for the throttle body, it does not have gas flow, just air flow. The injectors
are at each cylinder under the top half of the intake manifold.You must have changed the coil and ignition module also in order to get it to run. As you said you
cain't set the timing because the crankshaft pos. sensor and the camshaft position sensor does this through the ECM. The type of distributor you used does not have
camshaft position sensor.Of course if you did get it to run right with the new parts you will definately need a new high performance Mass air flow sensor at about $300.00 dollars. I can't see it working right at all. All of the above is taking for granted you have the OBDII HO engine.I'm thinking that's all they used since 1997.
Good luck and with my factory 4.3 I can outrun a lot of V8's.Hope this helps.
a recall on these problems in order to save billions.They instructed the service mngr. to fix these easy fixes when the vehicle was brought in for other work,hoping
the warranty would expire. It tells the mechanic to remove the trim off the left front door and run a jumper wire across a wiring connection. What a generic way to
proffesionally repair electronics.You should be able to bring the TSB's up on your computer.You will be amazed. But hey,I drive one too! If you can't find it, I'm sure
I have it on here somewhere so post a message if you can't. I live in WV close to where the Massey performance coal disaster happened. I know most of those guys and my twins work the midnight shift there. One is a mine foreman and he likes to
pile the work on his bro. I have'nt slept yet.They are safe.Thank GOD. So it may take a day or so to get back to you. Good luck and remember,I drive one too! LOL :sick:
After reading many posts about the blazers, I also have had many of the same issues...the clicking sound in the dash ( which all your info. has been quite helpful). My issue is I have a 2000 Blazer and literally EVERYTIME I put gas in it, no matter how much, when I take off the truck is very hesitant and doesn't seem to want to move too well then it will just snap out of it and all will be normal again. We replaced the fuel filter and the sending unit. Any ideas? Thanks!
There has to be about 7lbs pressure in the fuel tank for the system to operate properly. When the pressure raises, the purge solinoid is activated allowing the pressure to be vented through the charcoal cannister which allows fuel or fuel pressure back to the intake manifold or tank. Of course when you open fuel lid any
pressure would come out.Of course that is normal on any vehicle. You seem to
have trouble building and sustaining the 7lbs of pressure. You may have a bad gas cap or the hose in the top front of the tank is not connected if the tank has been removed, most people don't know about that hose and it breaks off the plastic where it attaches and can't be fixed unless that plastic connector is replaceable.
I don't believe it is but I could very well be wrong.These vehicles have a complicated
emmision/fuel system. The reason I'm thinking that may be your problem is It happened to me.When I put in a new fuel pump,I didn't notice that hose and it broke off.I thought it would not make any difference being that everything else was
right and the least it could do was just give the tank a little air.That is when I learned it has to be hooked up.I bought a repair manual and learned a great deal of info from it.I bought a tank from the local salvage yard and it works fine.You say after a while it runs ok. That makes me think you might have more of a leak than
the hose off all together. I advise you have someone check your system to allieviate
any maybe's or if's. I don't think it's injectors or fuel pressure regulator.Have someone check that everything is connected as it should be.Oh, and one more thing,my hose that went to the cannister was also stopped up. I hope you can
have your Blazer's purge solinoid and the hose etc... looked at and be saftely on
the road again. I hope this helps. Good luck. :shades:
