alright so for the last couple of days I've been having major issues with my jeep. Drove it to a buddy's house in biloxi, ms from my home in memphis, tn. Drove fine on the way down no issues of any kind. Next day We decided to go ride around and it wouldn't crank. I couldn't hear the fuel pump running and the gas gauge read zero even though it was full so I assumed it had a bad fuel pump. Took the tank down and test tested the fuel pump with a 12v source and it ran fine. At least it seemed to. Then i tested the wires running to the back and I was getting one wire with 12v's, 2 ground wires and one wire that seemed to be dead. So I cracked open the fuse box under the hood and checked the relay. It wasn't working. no ground going to the relay. So I spliced a ground wire into the rely and now the pump runs, but the jeep still won't crank. Seems like it may not be getting enough pressure up to the fuel rail, I took the tester nipple off and pressed in the valve and it just kinda leaked out instead of spraying. I'm stuck here. Don't know what to check what to change out or where to begin now. Could it be the auto shut down relay causing problems? Maybe a bad pcu? Some other ground not connected?
Also for the last few months the jeep has always been slow to start. Ran fine once cranked. But i would have to cycle the key a couple times to build fuel pressure for it to crank. I searched on here and heard it was a common problem and that It could be fixed with a 1 way valve in the gas line I just had not gotten around to it.
Sorry so long, I just really need some help here guys.
so here's what I have right now
gas gauge not working
fuel pump wasn't working due to no ground at relay. (couldn't find where ground was broken so I spliced in a new one)
with a ground spliced into the fuse box the fuel pump runs, but not pushing enough pressure for the jeep to start (i'm assuming this is the reason, seems to be very low pressure) Gauge still dosen't work even with splice in fuse
All help is great, even if your not sure just post up ideas for me to check. Kinda stuck here until I get this fixed so I'm open to trying anything.
Thanks as always
