94 grand cherokee

Please anyone help!! just bought it and brought it to the garage for saftey, got my upper ball joint fixed, got them to look over everything, all was good.. Next day my fuel pump shot while I was driving. Got a new fuel pump (inside gas tank on this one) still didnt work. By passed the relay with a toggle switch. Ran for a solid 10 minutes turned it off and put gas tank back on, now we got nothing.. No pinched lines, everything is hooked up still.. Help!!!!!

Thats really strange.. I had some issues with stalling on an old altima I had it was the fuel filter and intake was clogged with carbon and dirty gas deposits. But what you got is something Intense for sure.

I am hoping someone knows what the issue is, I get the concept but its just mind boggiling. Does not make sence, someone messed with the relays on fuse pannel. Does that have anythimg to do with it you think?

To my knowledge the fuses on a vehicle just regulate power, from the sounds of it your talking about possibly anywhere from an ECU issue (if you have one) to an electrical distribution system like your solenoid or something to that effect.

If it's running great for that 10 seconds then I would say it's an ignition issue for sure then, fuel injectors maybe? It's like throwing a dart at a board to be honest.

Did you also by pass the fuse? Just wondering... If so, what gauge wiring and did you put an inline fuse with the wiring? How did you diagnosis it was a problem with the pump?
