ok so today i was working on this damn jeep again and found that i have spark on all 8 and i have fuel pressure at the rail. idk how much pressure i have to go get a fuel pressure tester. could it be the cam and/or crank sensors not working right???

edit: i also did a compression test i forgot to write that. all 8 have about 135 +/- a couple psi.

 

did you ever figure out the problem im having similar problem if i pull the front left plug it will start?

 

if I remember it had a bad crank sensor. I think it's been a long time. It also had a crack on the passenger side head where the timing chain tensioner bolts to. So as the motor would roll over it would jump the timing chain. So I'd take the front cover off and check the timing chains and make they aren't too loose and are correctly set.
