So basically I've ran out of ideas and need to get this thing started soon. I rebuilt this motor over the last few months and dropped everything in. Double checked my f4-m63 wiring and to the best of my abilities it seems operational. But, I cannot get fuel or spark.
I probed around with the multimeter and the diagnostic section of the fsm and sourced it down to the fuel pump relay. I jumped the relay and the fuel pump came on when the key was put to start. So I got a relay and put it in, still doesn't come on when I turn the key to start.
Pulled the coil pack harness and ignitor, checked continuity to everything and it looks like it should be getting power but it is not. So I assumed again that it was probably just another bad relay, so I replaced it too along with the fuel pump one. Still no spark or fuel when I crank it. Everything is receiving power but it is just not being turned on or working.
I'd hope that all 4 coilpacks and ignitor aren't dead but I have no idea at this point. I had considered it being the ecu but it powers on alright and when the knock sensor was out it shot the right code for it. Now it just shoots the 55 code for data consult (which I don't have). Any thoughts, comments or suggestions would be greatly appreciated.
