#403 of 496 Never Again Will I GM
Jul 30, 2011 (11:13 pm)
My 1988 s10 blazer did exactly this, Stall, cool down, and start back up.
I tried everything, even the fuel pump. Still wasn't a fix, traded it in for another 1998 s10 blazer.
Then about in 2004 I bought a 2002 ZR2 blazer and what takes place at 118K?
$500.00 Fuel Pump!
I had it replaced, and then only at 123k, This stalling issue arises.
What do ya know?!?!
I'm back to the 1988 Blazer issue. Wow! It seems that GM and Chevrolet haven't fixed this issue. Hmm, I wonder why? Maybe because they seen this "issue" as a Cash Cow?
I would have to think so. Being that so many of us experience the SAME STALLING for no apparent reason. Hmm, I wonder why they pushed for their "Owner Loyalty" program so much? Do you think that it could be that so many of us are still having 2 and 3 decade old issues with our GM made vehicles, that they would have to get us buying another GM product by giving us a discount?
I would have to say so!
Google yourself this issue with any model year s10 and you'll read the same stalling.
No sure fix yet.
I've been a Chevy man all of my life!
There is NO Way on this planet that I'll pay for a Hummer H3, which is a FAT ZR2, totally based on the blazer zr2 and for 10k more.
Now I understand why GM scrapped the entire s10 line.
And I also understand why such a large company went under.
Way to go GM, Just change the names and keep selling the same cheap products.
Cavalier = Cobalt
Blazer ZR2 = Hummer H3
Blazer LS = HHR
LOL, seriously now!

What was wrong with your Blazer? Mine is doing the same thing and the mechanic is having a hard time fixing it!

Its the fuel pump!
After changing all of this:
Ignition coil, distributor cap and rotor, ignition module, sparkplugs, cables.
After changing all of them, it still would stall.
Then soon after I changed the plugs, it got so bad, it wouldn't even start.
Even after sitting.
Now remember this part. Everybody seemed like an expert.
Do not but the cheaper types of fuel pumps. Because the one that I have to replace now, only got me to 10 months!
This is the 3rd fuel pump. I'm saving up the $399.00 to but the original AC Delco.
Everything else is JUNK! Do not waste your money on the cheaper brands.
I was also told that the cam sensors are really problematic on the entire lines of ALL GM cars. Right now it's not the issue, but I will have it changed out asap.
Have you checked the fuel pressure?
That will tell you without a doubt that it is the pump.
When it stalls, check the pressure on the fuel line valve that's right behind the fuel intake. It is like a valve on your tire, but made of metal.
Stick a tip of a pen in there after it stalls. If the gass shoots out? Its not the pump.
But if it doesn't shoot out? It's definitely your pump!
There should be enough pressure to spray out like a bat out of hell. Mine just basically spurted out, and after that, no preasure at all.
Write back on here if you find the culprit.
I will say this, i'll never buy another GM 4 or 6 banger.
GM built them to fail, that's why GM and ac delco used to be one in the same.
To make money from their junk cars!
Look it up as I did, and learn.
A heart warming story of a massive company that got greedy and lost customers because of their cheap products.
This is why they needed the bail out money.
Massive Loss of car sales and customer loyalty.

Typo: fuel intake was supposed to be air intake.

The ignition control Moduel if its a 95 depending on if the sparkplugs come out the side of distributor or the top if its the top like mine take two screws off distibutor cap remove two screws on icm and change it for about 40 bucks make sure you put the temp grease on it before you install it . these get hot and cutr off the distributor from sending a charge to the plug to spark in the cylinder. so long story short change your icm it fixed mine . try it

The mechanic who changed to rotor tested the fuel pump and it is passed the pressure test. Also, changing the rotor did not help. Next, we changed to Idle Air Control valve and it ran fine for about 1 week and now it is stalling periodically again. I noticed that if it is not too hot outside it does not stall as much. My next "guess" is the ignition module getting hot and shutting her down. I am going to change the coil and the module and see what happens next. I will repost soon with an update.
Sorry you had trouble with the fuel pump! That's an expensive fix!
#409 of 496 dead battery like symptoms
Aug 21, 2011 (11:39 am)
Hi, I have a 92 Full size fuel injected Chevy Blazer. Usually runs strong but every now and them it won't start, then i'll give it about an hour and its ok. The engine turns over fine, but gets weaker and weaker everytime. I know its no the battery because Ive tried jumping it and even replacing the battery. any suggestions would be greatly appreciated.
Thanks, Joethe the
#410 of 496 Stalling on stops -- fuel pump failrure?
Aug 21, 2011 (2:05 pm)
My '95 Blazer stalls periodically when pressing the gas from a stop (stop light or after starting). It usually runs for maybe 30 minutes and then stall at a stop light when I lightly accelerate from the stop. Sometimes it won't stall on a short trip. It's fairly intermittent.
After it stalls it will never immediately restart. I have to wait ~10 minutes and then it starts every time. It runs great other than the stalling.
I also have an EGR code being thrown so I cleaned it and replaced the seal. The code is still being thrown but I don't think it's related.
At this point I started looking at the fuel system.
Hooked up a pressure gauge:
turned the key to ACC: ~60psi
Start the engine: 60psi but then goes down to about 54psi
Stop the engine and wait 5 min: ~52 psi
At this point I assume the Fuel regulator is good.
I left the fuel pressure gauge hooked up and went for a drive. It stalled in a parking lot. The pressure was around 40psi. I then relieved the pressure to zero psi.
With the key to ACC: zero psi
cranked the engine: still zero psi.
Waited ~10 minutes and put the key to ACC: ~60psi (then and cranked and started the engine -- it ran fine)
The fuel relay is good (it supplies power to the pump but the pump does not engage).
Since the pump is being powered but does not turn on it has to be a faulty fuel pump correct?

Well, to be honest, i changed the coil pack and module.
No differance, and shortly after changing the cap and rotor, it would not start.
So, after all of the other changes, a guy at checker said that the cam shaft sensors are terrible in all 4 and 6 banger gm's.
I never changed that....yet.
I then decided to check gas pressure, i can hear the pump charge sometimes, but not all.
So i figure its the fuel pump.
If i change the fuel pump, and it still doesn't run or start, i'm giving up and selling as a parts car. I've just had it with GM-Chevy.
At this point, i'm already saying-"Never again in my life will i spend another dime on GM-Government Motors.
Next truck will definitely be a ford f350.
I'm tired of dealing with garbage.
This Blazer ZR2 hasn't even hit 10 years, and it just hit 121,000 miles and has been babied.
My 88 s10 was built like a tank when compared to this piece of junk.
I even beat the hell out of it as if was my first 4x4.
The $40.00 fuel pump made it to 164,000 miles.
This $400.00 fuel pump, original, didn't make it to 120,000.
GM should be JM and stand for Junk Motors, as far as i am concerned!
But, never again.
FORD, here i come!

i am having the same issue with it starting and i can drive it but when i stop it stalls but i can start it right up if i put my foot on the gas pedal just a little bit.. but i really have to gun it to keep it started. but when i drive it and stop or even slow down to turn a corner the dang thing just stops.. i have never had this much problems with a truck or even a car in my life.. my blazer is at 189,000 miles on it and i have gone threw 3 fuel pumps.. but the first two times it never acted like it is this time.. but the first two was not cheap fuel pump this last one was.. it wouldnt such a headache if i had a great job and can afford to replace this crap ever 6 to 10 months..i really hate cheves now.. and i have replaced the spark plugs, wires, rotor and cap.. because that was one code that keep coming up. and now after that the other code that came up was my map but took that off to see if it was dirty or even clogged and it looks like its new.. and i have checked to make sure the wires on it was not broke or damaged and they look fine.. so i am starting to give up but cant right yet because cant afford a new damn car.. grrrrrrrrr
