You can unplug the fuel pump relay from the truck. using a small piece of wire jumper from terminals 30 to 87 (they sort of make a "T"). Just before you do this have a friend remove the gas cap and listen to see if the fuel pump is running (it should kick on for 2 seconds when the key is turned on). sometimes i put a transmission funnel into the filler neck to act like a megaphone to amplify the sound of the fuel pump running. If the fuel pump runs when you do this you either have a control circuit problem or a bad relay.

My 94 chevy pick up starts and files good but cuts out bad when put in gear and give gas


could be clogged fuel injectors or fuel filter could be plugged or your fuel pump is weak and needing replaced,what makes fuel pumps go bad in most vehichles is driving with less than a 1/4 tank of gas,it gets the fuel pump hot and works it too hard

My 94 GMC Jimmy 4x4 vortec, is hard to start, cuts off when i make stops, have to put it in neutral when i am at lights and still have to give it gas then. already changed the distributor cap and rotor...


I recently had similar symptoms from my Kia Rio, hard to start, bad idle in gear, etc.
Ended up being the idle air control valve, you can try cleaning yours with carb cleaner and see if there's any difference.
A clogged fuel filter can produce the same symptoms too, that might be the easiest thing to start with, then it's just a process of elimination from there.

1997 GMC Sierra 5.7 Vortec, replaced the fuel pump, fuel filter, spider injector. Still not getting fuel past the spider. fuel pressure is 10 psi! What could be wrong


10psi is, as I'm sure you know, about 48psi short of what you need to get it running. Did you verify you're getting a full 12 volts at the fuel pump connector? Check the ground wire also, ohm it out to chassis ground, shouldn't be more then a few ohms. Verify it's making a good connection and the terminals are clean and tight. High resistance in the wiring or a connector in the circuit could cause the fuel pump to not output the right amount of pressure.
Did you replace the fuel pump with an aftermarket unit or an oem part?

I have Chevy s-10 4.3 vortec, replace tank fuel


I'd put more fuel in it and see what happens. But I'm going to guess that you are having a problem with your injector. These cpi systems are notorisous(<spelling?) for problems.

I have a chevy blazer 94 S10 still quit on the road.


How is it running before it quits onyou. This could be the culprit of an egr valve. How many miles on thevehicle. The egr seems to die on a certain mileage pattern. Also youcould start by cleaning the egr valve before replacing it. This couldvery well help the situation, but this is just a guess. Hope thishelps!!

Chevy fuel problem?


try checking how much fuel preasure you are getting under the hood, there is a valve that looks similar to a tire valve that you screw a guage onto, that engine must recieve no less that 60 psi fuel preasure to make the fuel injectors even fire. try replacing the fuel preasure regulator.
