My 92 has no spark, and we cannot can any sort of signal or anything out of the wire that comes from the computer and plugs into the coil. We have tested continuity and the wire is good so it must be the computer not sending a signal. I was wondering if I could swap in a new computer that is know good and see if that fixes the issue. Then maybe I could have the compter repair or something, probably replace it.
(Thus the thread title)

First you need to verify the ASD relay is energizing, if the relay isn't bad itself, then it's likely the cam sensor or bad wiring.
If the coil isn't getting it's signal to fire it could very well be the crank sensor.

I have no doubt in bad wiring, the relay is good we did a test on it outside the vehicle. This truck sat a year or two and I have seen a couple bad wires. Is there a way to test it without visually inspecting every inch of the wire?

What would you be looking to get for the computer? I have no signal coming into the asd relay, however, two pins have constant power. I am assuminmg one is the power to energize the relay, and the other is the power that is being switched by the relay.
Aslo got a couple pluggins that have no home.
Bottom one is 3 prong and top one is 6 slotted with only 4 usable prongs
