Question about 2003 Chevrolet Blazer

1 Answer

2003 Chevy Blazer dies after starting. About 3 weeks ago my blazer started dying when I started it or I stopped at a traffic light. I took it to the shop and got a tune up. Now its doing it again. This doesnt happen all the time but this morning I couldnt get it to stay going at all. It starts but if I let off the gas it dies.

It's starving for fuel. The main component there is the MAS -- mass airflow sensor, very common to go bad. Tap on it and sometimes that will make it rev lower or stall. It's inline with the black tubing that goes to the air filter. They run around $200 but are very very easy to put in yourself with a little care.

93 s10 blazer runs and then dies and won't start again


check and make sure the sparkplugs are clean, I got a hunch it could be that small back module under the distributor cap, it is very sensitive to heat.

Hello, I have a 97 blazer and had replaced the fuel pump about 3 weeks ago. while i was driving last week the truck just died, with no hesitation or warning. now when i go to start she just cranks and...


try checking the fuel injection module out, ( "spider injection module"). My 2000 blazer did the same thing, fouled out the plugs and all, i hooked the fuel pressure gauge up and had good fuel pressure, just no start. I took it to the shop and they found the injection module to be the culprit. you'll need to replace the plugs if it was the problem since you cranked and cranked it over.

2000 s10 Blazer dies very 3-6 weeks for no reason


i would check your ignition system. you would need a meter for this but look for broke or loose connections. if it was a fuel problem i dont think it would just start up after 20 minutes. or you might try your ignition switch. if its shorting or something then ya well it would cut your engine off real quick

Same thing happened to me. I took it to the dealer, no choice. They told me that it is the engine. Didn't want to hear that, but I guess I have no choice.
