94 chevy starts than dies
truck started to act up,it would start than die after a few seconds. if u kept pumping the throttle you could keep it running SO.
i replaced the fuel filter, same thing
when i was looking at the throttle body , the injector the spray was not very uniform in shape.
and not alot of pressure
could not here the pump start when turning on the key SO
i replaced the pump.
tried again this time i could here the pump start and stop when turning on the key
but same result
also i could not here or feel the pump turn back on after starting the motor
on the throttle body where is the fuel regulator.
and is that the only thing left to control fuel pressure
i do not have a gauge to test pressure
let me know
thanks

Re: 94 chevy starts than dies
Well, you really to get a gauge to test fuel pressure to be sure whether that is an issue or not. The fuel spray from the injector not being uniform is no big deal and not a correct way to try and diagnose a problem. Check for any vacuum leaks or other issues that cause starting problems or would add/take away fuel and air from the mixture. Throttle body gaskets are known for cracking and sucking air. Injectors have been known to become faulty. You really need a proper fuel pressure reading and then go from there.

throttle body gaskets are new 11 months ago
as are all the sensors on top of the motor
fuel pressure was checked ok by mech.
fuel line replaced.
not sure where to turn

Re: 94 chevy starts than dies
Is the check engine light on at all? Can you give me the fuel pressure reading your mechanic checked as good? You've got quite a few variables here that aren't making sense. Also, even though you replaced the throttle body gasket 11 months ago doesn't mean it's good....it's a quick check to remove it and look, so you should do that just to eliminate that as a cause.

Re: 94 chevy starts than dies
i ahve a 2002 silverado and over the last couple months it hasnt stated up right away it just takes a couple cranks and a fwe pumps on the gas pedal and it rolls over and there is no issue after that. i was on my way to work this morning and it started up with no issues but after i took a turn the truck had no throttle response and now it will not stay on for more then a minute. any ideas??
Re: 94 chevy starts than dies
you should measure your fuel pressure. 5.7L fuel pressure is supposed to be 59 - 66psi
1993 chevy 1500 battery light on
Bought a t trailer wire harness put it on today. Where you just unplug the wires under the truck. Once I got done hooking it all up,tested everything.. when I went out there later and started it up my truck's battery light was on, the battery gage was almost in the red. I then turned on my blinker, once I did that my rpm and battery gage was pulsing to my blinker. I unhooked the wire harness and just plug everything back in like it was and it's still doing it. I had the battery checked about a month ago because my truck wouldn't start so I had it test. It was good and come to find out it was my alternator so I replaced that with a new one.. so anyone know what it could be
Re: 1993 chevy 1500 battery light on
battery light on and low charging voltage is a sign of an alternator not charging. Have the alternator checked. it should be under warranty
