Need Help

93 ZJ 4.0. Bought it not running, got it running by replacing PCM, cap and rotor, and crank sensor. Had an exhaust leak, parked it, replaced header. Now not starting again, replaced coil, spark plugs and wires, injectors, battery, grounded alarm, swapped relays. Still nothing. It is getting fuel, but spark only last a couple seconds and stops

It sounds like your crank sensor... Your asd relay will only power up for like 5 seconds or until it sees a crank reference at the pcm... No signal and it shuts the asd off.

It may be the crank sensor air gap.
