Then maybe I could have the compter repair or something, probably replace it.
The shipping costs for one. And if you read his post, he doesn't need a new engine. He isn't getting spark. No one would replace a whole engine because of this.

Well I have been told cam/crank sensor before so I want to rule them out first. How do I test them to make sure everything is getting/giving signal?

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

Does the ASD relay energize for a couple seconds when the key is first turned on? Did you check while cranking?

I checked while someone turned the key and then cranked it and only have power at the two prongs with constant power
