I currently have a S14 240sx with an s13 sr20det setup, the wiring harness was sent in for setup and everything was installed then the car was sold to me because it wouldn't fire, i have found the problem to be shes getting no spark. My current ECU, ignitor, and coil pack harness with new plugs were all tested on my running s13 sr20 and everything fired and ran fine on it. But when in the S14 I pulled a plug and a coil pack to see if it would spark when grounded out and nothing, so i don't seem to be getting the signal on the back side of the ignitor and no signal on a timing light when connected to the #1 coil pack but all wiring seems to be correct, i have constant power and ground to the coil packs and a constant power to the cas as well. Fuel pump turns on when car is in "on" position and have power though wiring in engine compartment. I also reset the cas and spun it while cranking to test any thought of timing problems. Any thoughts on what could be wrong knowing all the ignition components are working properly? Any thoughts could help

Start lookin at your crank and cam sensors. If they've gone out the will cause a "no fire" situation.

Sigh......... How about you download a fsm and test your cas first instead of spending monies on something that might not be the cause of the problem.
