No spark at coil, replaced original which had weak spark and would stall completely after a few revs but then replaced it. now it wont start I'm starting to think it's the way its wired. It might be incorrect but I can't find a diagram to save my life out here or online. I replaced the plugs, wires, distributor cap and rotor, pick up coil and ICM. What gives?

We need to start with checking for spark by pulling a plug and hold it against the block and then crank the engine. If you have spark then we need to look else where.

If there is no spark then I attached the info below on how this works.

It could be a wiring issue or just a faulty part. Unfortunately that happens frequently.

Please see the info below and let's run through this and let us know what you find. Thanks
