Question about 1996 GMC Sierra
Hello, I have a 1996 GMC 1500 V6. I pulled up to a stop light and it died and wouldn't start. If i put gas into the throttle body, it will start until the fuel runs out. I've put a new fuel pump in, replaced the fuel filter and fuel relay with no luck. I am getting fuel up to the throttle body but it still will not start. There are two fuel lines going into the top of the throttle body and one of them has fuel that comes out when the key is turned on. I'm not sure what the other one is for unless it is a return.
1995 gmc turns over ill not start replaced coil mod. in dist. not getting fire to coil 4.3 L

Check fuel pressure. Must have about 50 pounds to open injector valve.
May need new fuel pump or regulator.

Start injectrer deffcctive (unlikely) or out of circit!
But more likely fuel preshure is douwn! check your fuel pump for preshure, once started the engine can live with that for a time I think you will find it is that!
Pleased to be of help.........Bruce

the idle air control actuator is a common problem in this type of fuel injection an is mounted in the throttle body also the map sensor should be on top of intake make sure is connected right and have full vacum if so just tap on it with engine running and will miss if it is faulty please let me know if this helped or need further assistance i'll be glad to help.
