Okay so I swapped on a 4.0 head from a 91 XJ onyo my 90YJ

Thats all done, i put in a fuel pump, i wired the PDC and ECU , I have spark, I have fuel, it wants to start but is out of sync some how.

Like it will turn over and fire but not run.

I resett the timeing to TDC, firing order is right.

MY only thought is that the XJ cps i am using may not be reading my YJ flylwheel correctly.

Any one have any ideas, its really starting to piss me off.

Its soo close and yet sooo far.
