Automatic

Is the anti theft light flashing? Can you hear the fuel pump activate?

Ask Your Own Ford Question
Customer reply replied 1 year ago
There's no anti-theft light but I can heat the fuel pump.

Remove the starter interrupt relay and jump pin 1 to pin 3, let me know if that allows it to start.

Customer reply replied 1 year ago
I will have to do all this tomorrow morning; its 12:30 a.m check everything tomorrow.

Sounds good, I'll talk to you then. Thanks.

Try testing the volt relay on the drive side fender truck turn over but won't start.

Do you have a scan tool to check for codes? It sounds like there is something more serious going on such as failed PCM or wiring to PCM.

Ask Your Own Ford Question
Customer reply replied 1 year ago
No I don't have a scanning tool but did test the PCM socket or spot with a multimeter one side rate good.

Next step is checking power/grounds at the PCM and if both are good I'd have PCM replaced. Here is a connector diagram to help find proper pins to test. Let me know if you have questions or run into questions, you can reply to this answer at any time without additional fees. Thanks

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
