No spark when trying to start the engine on 98 chevy blazer

My truck just quit running in the middle of traffic. Has gas in it, after sitting, it started several times, then while in idle, died, and won't restart. I thought it was the fuel pump, but there is no spark when trying to start. could the lack of the power keep the fuel pump from running? how can I tell if the relay sensor is good? What other options could it be?

I have a 98 bravada where I was not getting no spark and no fuel, after replacing few parts it came down to the ECM fuse was blown. After replacing the fuse it ran for 20 seconds and stopped again. It blew fuse again. Put 30 amp fuse and it continues to run. Problem now is the heating and cooling is off. Been told could be a short in cable or something in ECM is shorting. Was told by parts guy at Checkers that if putting higher amp fuse in blows as well there is definite problem with ECM. As of now have not had ECM checked.

Check for dead battery. Test wipers, radio, headlights and heater fan. If all work normally, battery is probably charged and you may have bad starter or alternator ....

Good luck...

2000 chevy blazer getting spark&gas but want start

check your exhaust piping for any sensors that may have been damaged or unplugged during your manifold gasket job. Usually you can find them between the motor and the muffler, as well as between muffler and back of car.

how are you sure its getting gas?

2000 Chevy blazer it stalled and shit off now it won't turn over.

Sounds like the engine is turning over but not firing off. Needs 3 things to run, fuel, air and spark, so you are missing one. A small amount of gas can be shot down the throttle body as you try to start to see if the engine tries to run. Otherwise check to see if the spark plugs are firing.

I have a 94 chevy s10 blazer. It has the 4.3L Vortec. When i get in traffic or if i leave my truck running without moving for any period of time it starts flooding itself out and sputters. When it starts...

What it is is that the engine is running rich, check MAP sensor acts like a choke, make sure vacum hose is good and that it has vacum if ok you'll need to check injector's or the fuel pressure regulator or the fuel line for leaking fuel, the bad thing is that to get to these part's you will have to remove the in-take magifold , after removal of in-take have some one turn key to the on position and look for fuel leak's.

1999 chevy blazer wont start


if your losing fuel pressure after the pump runs the drain back valve in the pump has failed.

and i doubt that you are seeing enough fuel pressure to run a vortec engine.

low fuel pressure equals a non running vortec

1986 Chevy s10 won't start

small gas engines 101. gas+air+compression+spark=vrrrrrrroooooommmm
i doubt its a fuse. make sure all cylinder have good spark. try and run some seafoam through the gas tank and i would look at the timing - im not sure how you know the timing didnt skip but that sounds like your problem.

Try checking those sparks again. It could be a weak spark not enough to start your engine.
Make sure also that you have fresh gasoline, as gasoline or diesel looses it's effectiveness after a long time.
