A 2001 4.3 blazer cranks wont start fuel pump is pushing fuel what fires the injectors the problem is off & on

Question:
new fuel filter new tune up when i put fuel in the throat it will fire until that gas burns off then dies. it does not do it all the time its hit or miss but when it does do it ill get fuel flow all the way to the release vale. it does not pull any codes either

Answers:

Can I repair/replace the brgs/pulley in alternator for my '05 Chevy Colorado without replacing the alternator.

I would guess a bad fuel pump. GM had trouble with these for many years. I have done over 20 GM fuel pumps in the last three years.

My Truck has vibration after 170Kmph.?

My 2000 Blazer just ate its fuel pump, left me stranded. Actually out of the 8 blazers I've owned...4 of them have dumped on me.

Has anyone got an exploded diagram on a Mk3 Polo front suspension? Now wise cracks or smart answers plz.......

This is a common issue on the Blazer for all its years. GM won't fess up and make it a recall. Pump, sending unit has to be bad, not enough psi, clogged line due to sediment. cause since she fires up when you dump in, that rules out any spark issues.

Heater problems with Dodge Dakota.?

Don't quote me but my mind says 17 psi for the fuel or 34. Recall something like that from the tech.

I have a 1990 cadallic fleetwood (Sixty Special).With one problem,the security will not let me start the car.?

...Awi is on the right track.Confirm fuel pressure and volume delivery when in no start mode. My second GUESS would lead me to believe that a sensor/sensors are giving false but(within spec) readings. Many GM's enjoy extra body/engine ground connections to overcome illogical failures.

1997 Chevy Cavalier?

Fuel flow at the release valve?
You will need a test gauge about $45
I would expect 30PSI or more.
The injectors are fired by the computer.
In a quiet place when you first turn the key on you should be able to hear the fuel pump in the tank run for 3 - 5 seconds, enough to build pressure in the fuel rails.
At normal pressure's it wont just dribble out of the schradder fitting, it will hose you.

i drive 1999 altima. it has 60K miles.car makes noise while making left turns.?

This thing requires 41+ PSI fuel pressure to start. Your fuel pump may be just weak. Quite typical for gm.
