I have a 86 fiero I got a few weeks ago, it had been sitting for 6 years, I have replaced, fuel pump, fuel filter, ecm fuse, dist cap. Ign coil, spark plugs, rotor, wires, pick up coil and had module tested it is good. And battery of course.

the fuel part is working great
but no spark, how can I check if ignition coil is getting spark?

im not sure what to do next, computer? Wiring harness?
also, the firing order is 1, 3, 4, 2 going clockwise and I belive the 1 is by the belts, where does the one start on cap

If you use a noid lite on the injector harness and its flashing the circuit is okay -the injector is defective
