Customer Question

1996 ford f-250 w/460 & E4OD transmission.
Engine cranks but won't start.
Problem started as intermittent then just would not start.
Replaced the ignition module, started fine.
Problem reoccurred 2 weeks later intermittently then would not start.
Replaced the coil, it would still crank but not start.
I checked the coil with a spark plug tester and wasn't getting any fire, then 5 minutes later it started fine.

HelloCustomer
Thanks for choosing JustAnswer.
My name is Vladimir.
I have a question, please reply in this thread.
Did you install an original Motorcraft ignition control module?

Customer replied 1328 days and 17 hours ago.

no I bought it at napa

Well, since your problem is intermittent, I would use an original Ford part.
I have seen a lot of problems with such non-original modules , especially when they get hot.
You should also check that you get +12V at the ignition coil and module ( Red/Light Green wire) when the engine won't start.
Use this wiring diagram graphic:

Customer replied 1328 days and 17 hours ago.

Where would the problem be if I don't get any voltage to the coil?
Could it be a resistor getting hot then having time to cool off?

Sorry for the delay, I had my breakfast.
Voltage to the ignition coil, module and distributor hall-effect switch comes from the ignition switch via the fuse #22.
What resistor are you talking about?

Customer replied 1328 days and 17 hours ago.

It was just a theory posed to me earlier by a friend, I just wanted to verify.
Sounds to me like I might just have a loose wire somewhere, maybe.
Though it wouldn't hurt to thouroghly clean the ignition module connections either.

Your vehicle does not use a resistor in the ignition system.
Yes, it is possible that you have a bad contact somewhere in the wiring.
I do not think you have any problem within the ignition module connector, it is a quite reliable sealed connector. Check for +12 voltage at the moment it has no spark and if it is, try using an original Motorcraft ( I suppose it should be DY1075) module.
