1992 s10 Blazer fuel issue?

Asked by Jan 17, 2017 at 12:30 PM about the 1992 Chevrolet Blazer 2-Door 4WD

Question type: General

Hey everyone!
So, I could REALLY use some help here. I've been
searching and 'googling' all damn morning, and
can't seem to find much of anything.

I have 92 s10 Blazer that I love, but she's been
having some major issues lately.
She was starting and driving just fine, until I went
out to warm her up before heading to work one
morning. She started shaking, sputtering, check
engine light came on, then died. Tried to start
again, same thing. I assumed it was a fuel issue
(which I was right about).
This is what was replaced:
MAP sensor
Fuel pump
Injectors rebuilt
NEW distributor
Caps, plugs, wires, rotor
02 sensor
Vacuume leak repaired
IAC valve
Timing done
Even a new freakin battery.

She ran great for literally 4 days. Went out
yesterday to start her up, and the same damn thing
happened.
What gives? Could something have not been
replaced properly? What else could it possibly be?

ANY input would be greatly appreciated. For real.
Oh, and of course new fuel filter blah blah.

Thanks!

When you work a lot near a 'vehicle from hell', being stressed, sometimes you forget a small thing. It happened to all of us, at least once :) You should try checking what is the error when the light is on. This is an obd1 I think so not all testers work with it if I remember correct.

Maybe a bad electrical connection to the fuel pump.

Did you happen to check the fuel pressure? And what was it. One possibility is the fuel regulator may need to be rebuilt. Another thing is the coil could be weak, that could be tested. You said a new distributor, did the include the ICM? And you don't need a scanner to get the code stored in the OBD1......Turn on the car (DO NOT START IT*) and use a paper clip or a piece of wire to jump terminal A & B. DO NOT TRY TO START THE CAR*! You will see the SES (Service Engine Soon) light flash out a code. It will flash out each code three times. The first code you will get will be a code 12*. It will be a single flash, followed by a short pause, then two flashes. It will then pause for about two seconds or so, and flash the code again until it was read out three times. The code(s) after this will be your trouble code(s). Make sure to have a pen & paper handy to write them down. When you get back to code 12 it is finished...IMPORTANT!...Once you are done writing down all your trouble codes, turn off the ignition and remove the jumper between terminals A & B. To reset the codes, simply pull the ECM fuse (Blue 15A) for one minute. Doing this will reset the ECM back to factory settings, and the driving parameters will have to be relearned (the car will do this itself). *Starting the car with terminals A&B jumped or jumping the terminals with the car running, will force the ECM into limp home mode. This can damage the ECM and/or the drivetrain if the car is ran/driven like this.
