You should be able to hear te pump(in the tank) run for 2 seconds when you turn the key to "run".Ifnot,locate the plug at the sender unit for the fuel tank(not sure if you will need to lower the tank to do this).You should get 12v on the(possibly purple) wire when you turn the key to run.If you do,then the pump is most likely the trouble.(Try swapping the fuel pump relay with one of the others-like the A/C compressor relay,before you do all of this-highly unlikely a bad relay,but not impossible).

SOURCE: 92 CAMARO Z28 5.7 TPI CRANKS IDLES, GOES DEAD

Have you tried to pull any DTC codes. Here is a link for you so you can pull some codes, but you may have a bad Ignition Control Module (ICM) it's around $40.00 at Auto Zone and they can give you the step by step instruction to replacing it with common tools. The ICM is common to go bad after a few years due to time and corrosion. It's location is under the rotor in the distributor, as it heats up if fails or any changes in the engine speed. Check the wires to make sure there are no damages. Keep me posted be glad the help. http://www.troublecodes.net/GM/

SOURCE: 91 camaro 5.0 5sp no injector pulse and no power to fuel pump

Using a multimeter check the wiring for power at the pump and at the relay. It sounds like a bad relay.

Stored 2 years... wont start. What should i check?


Sounds like you have spark and no fuel.
Could be bad gas, sludge in the fuel line or injectors, or a failed fuel pump.
If you check fuel pressure with a gauge and it is normal, you may need to drain the tank and clean out the injectors.
Gasoline turns to shellac after several months, which acts like varnish.

My '91 GMC Jimmy suddenly died like it was out of gas. It restarts, but idles rough, sputters and pulses. Plenty of fuel comes out of the injectors, but it wants to stall and die.


start at the beginning fuel pump pressure at the pressure regulator then look for ignition problems , check mass air flow sensor if equiped

After hot engine wont start and smells like gas


Most likely causes are bad engine coolant temp sensor OR leaking fuel injectors. Bad engine coolant temp sensor will give computer false reading and computer provides wrong air fuel mixture. Leaking fuel injectors will load the engine with raw gas--just like flooding it. Try pushing the gas pedal to the floor and holding it there when cranking when hot. That forces the computer into "clear flood" mode and it shuts off the injectors. If it starts up with pedal down, that would be a sign of leaking injectors.

I have a 94 Caprice 4.3 v8 and the past week it will run fine the acts like it's not getting enough fuel back fire real loud and die and it takes bout 10 mins before it will start again then when it does...


not starving fuel but "flooding out" and putting unburnt fuel in the exhaust system which ignites and damages mufflers and cat converters
check for excessive fuel pressure or bad /leaking injectors

91 honda accord wont crank


There is a sensor under the left hand side of the dash that would not allow it to start, provided that you have replaced the electronic spark module inside the distributor first, which is what it sounds like it would be, When you say you replaced the distributor I assume you replaced it complete!

How to replace fuel pumpon 2003pontiac sunfire


Remove the gas tank (careful when taking it down. Fuel may spill out the top) and in the top is the fuel pump.It may be alot easier is you have a vehicle hoist and a lowering support for the gas tank.
