Ok so the fuel pump wouldn't come on. Replaced it and everything worked. Next day I stalled out like a noob and now the fuel pump wont come on. Replaced the relay. Tried relieving the fuel pressure to get the pump on and nothing. Help somebody please

Relay is good? Does check engine light stay on? Do you have 12v to the pump?

Food for thought: Its common for people to install the pump, but upon raising the tank they smash the wires up on the body, Drop the tank, un-plug the pump, then plug it in.. If it works then you shorted the wire to ground.. Meaning don't smash the wires when raising the tank back up..

New and old relay are good. I checked the old relay as well. I could get to some of the wires under the fuel level indicator under back seat and they seemed ok. But my next step was to drop the tank and check all the connections like u were saying. That just takes alot of time and its my only car and I can't get off work to do it nor can I take off. Its got me stressed blah

wires run on top of the tank, if you installed a new pump chances are you mashed the wires..
get a test light and check for 12v at the pump also.. if no volts at pump then back track to relay to see if you have 12v there..

On my hatch when I bought it the fuel pump wouldn't come on and when I dropped the tank it was the wires that goes from the connecter to the pump inside the tank one of those was burned up after I fixed that the car runs fine now going on 2 years

check fuse 14 i believe under the dash, one of them is linked to the Fuel pump, DESCRIPTION WILL NOT SAY ANYTHING REGARDING FUEL. if 14 isnt it, check every single fuse.
