Jump the ASD relay, and manually ground the coil. (put the coil wire somewhere that you can SEE the spark. putting an old plug in it makes it easier.) Verify the coil actually WILL fire.

If that works, check the wires for the crank sensor. Make sure you are getting 5 volts to it. If ok, test continuity of other wires. (there are only three, total) If THAT tests good, might be bad PCM.

 

Curious about the outcome as I'm in the same exact spot with my truck.

I ordered a PCM from Solo today because I feel pretty sure that's my problem.
