Damn.....I had that same problem! Slid a stick of dynamite into the fuel tank with the fuse sticking out the top, put a match to it and RAN.

ECM has to see crank slow down, combined with crank tooth count, to know which cylinder to send spark to. Going directly to the starter relay may bleed off too much pressure for the ECM to recognize which cylinder it's on, so no spark. Solution is to install the correct ACR wiring harness, and have them turned on in the ECM.

There is a direct correlation between a poster's ability to articulately describe their problem(s) in detail and someone actually being able to help them.
