Mechanic's Assistant: Cars do make very odd noises -- They help the mechanics figure out what's wrong. They are terrific with my old Grand Cherokee. Are you hoping to fix this yourself?

With the key on, if you remove and install the PCM relay does it click in your finger tips?

I didn't check and of the power and ground wires I just went ahead and bought a new pcm and got it all worked out and when I went to install it I got the same thing it will spin over but no crank, no dash lights nothing on my instrument cluster is working I don't know what's wrong
Ford Mechanic: Chris (aka- Moose), Technician replied 2 years ago

So everything is identical, just like it was before?

If so can you go back over everything we have talked about and let me know those results?

Ok fixed my pcm, now my transmission is overheating. I put two bigger coolers on there and now I only overheat on the highway and I'm not pulling anything it will get up to 210 and normally by that time I'm getting off the highway and driving a backroad and then it drops back to about 150-180 I checked the flow and it's about 1qt in 15 sec help !!!!!
Ford Mechanic: Chris (aka- Moose), Technician replied 2 years ago

We are not allowed to help on new issues until there is a rating on the post for the original concern that is not related to the new issue.

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
