Thanks for visiting Just answer
When it does not start does the security light come on while the key is in the crank position? Or does it turn off normally?
I never looked....so I can't say...
it may be days before it happens again....
Okay, well here is some things to keep in mind. Since the relay and fuse boxes are OK, it has to be a problem with one of the componets that allow the vehicle to crank.
So, when the problem is present shift the vehicle into N
If the vehicle will start in neutral there is more than likely a problem with the neutral safety switch.
If that does not help, try to check for power right at the starter. What size engine is this?
I am going to get a wiring diagram.
Funny you should mention that...I have tried to start it while in neutral...no joy there....it is the 5.4...eddie bauer edition if that matters....
ok when the engine will not crank access the starter relay.
Check for power at pin 30 at all times. If there is no power check the fuse 101 30A
check for power on pin 85 (tan red wire) with the vehicle in crank. If no power there, you could have a neutral switch problem.
If OK, check for ground from the PCM.
If the pcm isn't grounding the relay it will not turn over.
If all is good, check for power at the starter itself. Should have power on the red wire all times and power at the yellow/light blue wire in crank.
If there is power getting to the starter try hitting the starter.
If still nothing replace the starter.
I will check it out and let you know.....
what happened to your answer.....I don't see it anymore....doesn't it get saved?
It should be saved.
