Crank No Start. AGAIN
#16
Just simply unplug the spout and see if spark returns to rule the PCM out. If spark returns and still no start then test the ICM. Here is a good test procedure.

OK test the ICM https://easyautodiagnostics.com/ford...module-tests-1
The distributor changing is of concern. If the ICM is OK then we should maybe check the gear on the distributor. Did you have a timing light when you set timing?

all my ICM’s are grey, it’s a distributor mounted ICM
the one for my old distributor was grey, a new one I have laying around is grey, and the one in there is gray too. What was that thing you mentioned earlier about the PCM? If the spout is unplugged and spark returns it could be the IDM or the PCM?

MY bad. I looked at post 2 for fuel pressure and saw a 1994 truck was posted. Here is the correct procedure for your distributor mounted ICM.

Here is a coil test if the ICM test good. https://troubleshootmyvehicle.com/fo...gnition-coil-1

Well it’s gotten too dark and cold out to continue working, so I’ll pick up where I left off tmrrw. I do have some concerns with the grounding test for the ICM, I tested voltage through the ground wire (pin6) to positive battery terminal, and got 7volts, need 10-12v. Then I remember I had left the Key in the on position so I turned it off and checked the ground circuit again, 12v. Doesn’t mention in the testing section for test 2 grounding circuit if the key needs to be left in the on or off position for test 2. Would appreciate some clarification

I tested the ignition coil before finishing the ICM tests, I am getting 12v to the IC, and I am getting a switching signal (verified by an LED test light), so that concludes the ICM and PIP are transmitting a signal, but the ignition coil is not firing. Next course of action would be to replace the ignition coil. I did replace the ignition coil about 15months ago with an NGK I bought on rockauto. Would not expect the IC to be the failure point. I will get back to you guys with results after replacing the IC.
