1995 Ford E-150 has no fire
I have a 1995 Ford E-150 van that has no fire. I have read codes, nothing. I have replaced distributor, coil, and wires. Using a spark tester, I have no fire from coil to anything. If I check signal to coil, it looks to be there, but when I test the spark at the coil, nothing. Do these have an external ICM or is it built into the distributor? It is not mounted outside on the distributor and it has the round plug. Any ideas?
