Help needed - 04 ZJ fuel system
OK, needing some advice for my 04 ZJ (4.0L).
A couple weeks ago, it stalled and would not restart. Engine was trying to turn over, but it wouldn't ever catch. I assumed (based on advice from a friend) that it was a bad fuel pump.
...Jump ahead a few weeks...
I get the thing pulled home, dropped the tank, swapped the fuel pump, changed the fuel filter, put it all back together, tried to start it, and it still won't start. I am stumped.
I have since found out a couple more things:
- The fuel pump relay DOES seem to be functioning. (When I have my wife turn on the electrical system, I can feel the relay "click" on then off.)
- The pump does not seem to be engaging when the electrical system is turned on. (I can't hear the pump running at all when the key is turned.)
- The fuel line clearly is not priming. (Since swapping the pump and the filter, I have tried priming the line multiple times, yet even after this, the brand new fuel filter still has no fuel in it, meaning the pump is not priming the line.)
Any ideas/suggestions?? Other things I could check myself? Thanks in advance!!
