Ok so I just got a 1991 Cherokee inline 6 4.0L HO for $300 It was not running when I got it and is still not running.
I'm stumped it has all the things it needs to run but it won't.
I have a new fuel pump. I checked the fuel at the rail and there is pressure
I have over 120 psi per cylinder
I have spark at all 6 cylinders
and I have air
I think the timing may be out but not sure how to change it or if it is even possible
so I have all the things I need to run but it does not run
I tried changing the ecu but that did not help
I also unplugged the CPS and then there was no spark and reconnected it and the spark came back.
I TDC the crank and the rotor and cap line up with #1 cylinder
I also tried quick start and that did nothing so it’s not a fuel problem cause I could smell it on the plugs when I pulled them
