Exclamation Spark, gas, and compression no start

So I got a 92, 2.9L, and the mug won't start. It cranks, but won't catch and fire. It's got spark, gas, and compression. I was driving it down the road and it just shut off while going 40 mph and won't start up again. Swapped the computer, traced the wiring, and the distributor. Our last guess is the wiring harness is bad or the PCM? Thoughts and maybe some help on where to buy a harness aside from a pick and pull?

How did you verify spark and gas. If the plugs are lighting and the injectors are firing then the ecu and wiring are working. Cant have spark and fuel without a functioning ecu...

Check the timing, could have jumped time or lost the crank sensor.

All the plugs were lighting, and we hooked up a tester to each wire. We checked the timing even though the compression was there, why not, and it was fine. Took to a shop and the wiring harness was the issue, those POS 2.9 love to over hear and this once burned two spots on the harness. Took a donor from a 2.9 1989 and it runs like a dream, except the fuel, temp, and tack gauge ain't working. Thoughts?
