Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name isCustomerand I can assist you with your question. Are you looking for possible causes or would you like me to walk you through this diagnoses?
Are you sure all of the fuses are good? Check the 15 amp fuse 21 in the central junction box as this feeds the transmission range sensor. If the fuse is good, then the transmission range sensor should be getting power to it with the key in the CRANK position. Then it should send power out of the transmission range switch in park or nuetral (provided the switch is good) to the starter relay. Here is a wiring diagram.
Under the hood, passenger side near the firewall
Engine control module
Powertrain control module
I agree. I dont think it is the problem either.
Did you check power in and out of the transmissinon range switch like I mentioned?
Please answer my question.
YES, that is why I want you to check it.
No sir. It is a different circuit for the reverse lights than the starting circuit.
Hello! It'sCustomerfrom just answer.
I am just checking in to see if you need any further assistance?
Let me know!
Did you check/test it first to be sure it is bad?
So have you checked power going in and out.. like I mentioned awhile back in this thread?
And what were the results/readings?
Ok, no problem. Its your money and your vehicle. I just ask that you dont get upset with me if these dont do the trick. Let me know.
So, lets back up and so it my way. Check the input and output of the switch with the key in the CRANK position. Let me know.
That means the ignition switch is not powering up the starting circuit. Sounds like a problem with the mechanical part of the ignition switch..lock cylinder or something along those lines.
