I have been told I need a fuel filter, which I replaced. And it still does the same thing. Then I was told , a fuel pump by one mechanic, a #1 injector by another, simple tune up by the third one. After replacing fuel filter, It still looses power , after about 15-20 miles it actually shuts down, and now it will not stay cranked. Can you tell me where the fuel pump is or give me a link to the scematics for this model?
That's right! Fuel pump is in the fuel tank, some car has opening to acces in the trunk under the carpet, some car you need to take down the tank, my advise is get your self a service manual for your truck its about $25.00 and it will help a lot.

Replace the fuel filter first. When you turn the key on, the fuel pump should run for a few moments, then turn off. If it keeps running, then replace the pump as well. Suggest having the fuel system pressure checked at the engine itself. Hope this helps!
what gave you the reason to change all the things you have replaced. and just remember just because you replaced something doesnt mean that the part may not be defective... check for fuel, fuel pressure, spark, compression first. then i can help you.
Your fuel filter may be at it's life time and will need to be replaced. Start with the simple and replace that, the other thing also that would cause the engine to shut down would be a faulty oil pressure sending unit. What is the oil pressure on the dash when the engine shuts down. You need at least 8 PSI to have the engine stay running. Check your Fuel pressure at the shredder valve and you should be 62-65 PSI with the engine not running and fuel system energized, once the engine is running it should drop about 5PSI. The last thing that could cause this would be a bad ICM, once the ignition system heats up the ICM fails and the engine shuts down. A mentioned, start with the simple and replace the fuel filter and check your fuel pressure to ensure your fuel Sending unit has not gone bad and will need to be replaced. Good luck and keep me posted.
the battery indicator light usually comes on after a lose of power. Sounds to me like either bad gas, clogged fuel filter or a bad fuel pump. Easiest way to check this is have someone turn the key while you stand at rear side of vehicle and listen for the whinning noise a functioning fuel pump makes as it pressurizes the system.
P.S you dont have to start vehicle to check pump. only requires turning the key to the on position. Good Luck
Only one question.....was the fuel filter replaced? On a jimmy the filter is usually mounted to the rail up under the passenger door on the drivers side. Sounds like there is some sort of obstruction that is preventing fuel from making it from the fuel tank to the engine. I would have thought that the mechanic would have replaced the fuel filter first thing, so maybe it has already been done. Only you and the mechanic know the answer to that one. Good luck with your problem.
The fuel pump relay is in the glove box. There is a panel in the back that say relay on it and it's in there, the middle relay from the three is the fuel pump relay.
The other thing to is change your fuel filter, that is on the inside frame rail under the driver just on front of the transmission cross frame.
Also check the fuel pressure at the shredder valve,you should have 60 to 65 PSI in the system to have the spider injection system you work.
Recap: replace the fuel filter first since that's the cheapest and easiest thing to do, check the fuel pressure at the shredder valve and you can do that at Auto Zone and they can give you the step by step instruction on how to do it if your nor sure how to. Take about 5 min to do.
If pressure is low,then your fuel pump may be getting weak and needs to be replaced soon. At worst, it's going to be your Fuel injection system since they have a bad history of the poppet valve going bad, but we deal with that last.
Good luck and keep me post. Be glad to help.
