My 1995 GMC jimmy isn't getting power to the fuel pump, I put in a new relay and thats not it , What do I do?


firstly remove the fuel pump from the tank and test it by connecting the leads from the pump to a 12 volt battery....if the pump turns on then test the wires running from the pump to the front of vehicle.....since you have replaced the relay then that is not the issue also some vehicles have two sets of fuse blocks instead of the standard one ......does the pump spin up at all when you turn your key to the first position without starting the engine? if it does then you need to test the fuel pressure getting to the intake....i replaced a pump recently that was only pushing 8psi to the engine instead of the needed 52-66psi new pump fixed the whole issue

1995 GMC JIMMY WONT START UNLESS I PRIME IT THEN IT JUST DIES ITS FUEL INJECTED


It sounds like you have a defective fuel pump. The pump is locate inside the fuel tank, the fuel tank must be removed to replace the pump. Please follow this procedure to remove the fuel tank.
Disconnect neg battery cable, safely raise vehicle, place floor jack under tank, loosen gas tank straps and allow tank to slowly drop halfway, disconnect( this is the hard part) fuel lines,and power connections at tank. Drop tank. With a brass hammer/punch carefully remove retaining ring/seal.Reverse to install.A new pump module will cost you $300-$400 at the dealer. Don't use a cheap pump replace the entire assembly because this is a float/sender/pump/ in one. Replace your fuel filter too or the fuel pump warranty is voided..

My 1995 GMC jimmy 4x4 just stopped running. Had it towed home. mechanic told me it was a fuel pump. just changed fuel pump and sending unit. Tried to start and will not fire. Put some gas in intake and...


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.
