I have a 2007 Ford 500 I went out to start the car turn the key on and I only get a click from the starter relay I can use a jumper wire from the battery to the starter solenoid and the engine will start but the cooling fan runs at top speed when you put it in gear it starts off in second or third gear and will not shift into overdrive does anyone have an answer I installed a new battery about a month ago I'm new to this site how do I know when someone reply to my problem?
I HAVE A UPDATE I replace the transmission control module. I had to get a remanufactured control module because Ford has discontinued it after replacing the transmission control module the car is doing the same thing will not start with the ignition key car is in limp mode and I cannot get it out Ive taking the negative battery cable off and turned the headlights on to drain any voltage that might be stored in the ECM it's still doing the same thing does anyone know how to get the car out of limp in mode or do I need to have the Ford dealer to calibrate the transmission control module with the ECM? taking the consideration it's a $1,000 car and they want $240 an hour to diagnose it.

 

Borrow the wiper relay (C1491).
If it doesn't work with the key still, check below:


1) Check the F10 (30A) fuse see if it's good, then unplug the starter relay, voltmeter red to terminal 1 of starter relay, voltmeter black to battery negative post, then turn key to START position, you should expect battery voltage
2) Unplug the starter relay, key in ON position, ohmmeter set the dial to 200Ω, red to terminal 2 of starter relay (circuit 32, Red/Light Blue wire), black to battery negative post, you should get non-zero 5ohm or less.
3) If not, it could be a problem with your PATS causing your PCM not sending ground signal thru terminal 2 thru circuit 32 to terminal 2 of your starter relay.

 

Would it be accurate to ask why did you need to replace the battery earlier, could it be there were problems starting and battery replacement provided a temporary cure ?

There are reasons we ask and there is very likely a questionable connection problem within the electrical system ?

 

the reason I replaced the battery was the battery was getting old and I didn't know if it was stay up during the winter because I don't drive it that much

 

Did you have the starting problem before replacing the battery ?

 

I never have any problem with the vehicle before this happened the only think I can think of is I tried to connect my low pressure AC hose to the A/C connector and I have to move the wire loom out of the way to get the connection to fit then I tried to start the car and it would not start that wire loom may go to the computer I don't know

 

hello is the PATS the same as a Ford smart junction box under the dash

 

I ran a wire from the key switch to the starter relay the car will now start but when the engine starts up the cooling fans immediately comes on at full speed and the car will not shift gears is the Pats the same as a smart junk in box because I checked the smart junction box I have power coming in but nothing coming out should I replace the smart junction box?

 

It's not the PATS when you already tried two different methods:
1) battery directly to the starter solenoid
2) key switch directly to the starter relay

And when you can start it at the starter relay, refer to the previous diagram check circuit 1785 do you get battery voltage when key in START position? Do you get ground signal at circuit 32? <- (this is important and there is a workaround, you can simply ground this circuit) Circuit 1786 do you get voltage with hot at all time? You don't need to check circuit 33 because you can start it at the starter relay previously.

The cooling fan running non-stop is another issue it can happen if you have a bad relay. Check pinpoint KF below.
If you need to reset adaptation on your TCM, I assume you already programmed it when you replaced it, check foxwell NT510 Elite w/ Ford on Amazon, keep it if you like it.

 

I need to explain what I did I purchased a new ignition switch and the car still would not start with the engine so we ran a while from the ignition switch to the starter solenoid and the car will start with the engine switch we also have a problem with the brake lights not working I took the brake light switch out and it was not working properly I got it fixed. Then i tested the smart junction box under the dash I have power coming into the junction box but nothing coming out the codes that I'm getting are referring to the computer is not receiving messages from the smart junction box or I think you're calling it theft device should I replace the spark junction box this car is a mess for people have been working on it for years and I'm the type of person that just cannot let go of something I can't fix
