Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. Are there any codes in the computer? Can I start by getting your VIN? Thank you!
Thanks for the VIN! Based on my experience, this probem is either a bad PCM, instrument cluster or a shorted out sensor (shorting the PCM out).
I bet there is no communication with the PCM when this happens.. and this is why the engine does not start. I would start by checking for a 5 volt reference from the PCM to the TPS with the key on when this happens. If the PCM is not sending out 5 volts, then check for any shorted out sensors and check all powers and grounds going into the PCM with the key on. If all checks out good, the PCM is bad and will need to be replaced.
Hello and sorry for the delay! The TPS is located on the side of the throttle body. It should have three wires going to the TPS
Here is a picture of the location of the PCM. It is on the left side of the diagram. Passenger side of the engine compartment
Sounds good! I do work tomorrow during the day but I will be on line tomorrow night after work. Talk to you then.
Sounds good! No problem! Take your time and let me know when you can.
The clicking you are hearing are relays. If the key was on when you reconnected the battery, then the relays will click.
The reference voltage going to the TPS sensor should be the brown wire with white stripe
Hi Jim! Thank you for the reply. I'm glad to hear vehicles up and running. However I have never heard of a recent procedure for the antitheft system for a ford. Otherwise a car thief would just reset the antitheft system and would be able to steel your vehicle.
