I had my 95 F350 in the shop after going down 2 week's ago, the valve cover gasket's/wiring harness was melted for one thing, got that fixed. Well it also appears the Computer is bad, it has been wet at some point in time so im assuming that it possibly did the day it died and that is what finally killed it. Now im having issue's finding one, everyone says they have to have them sent back to be rebuilt. As many of these truck's are on the road i find it Hard to believe that no one make's them or no one has them that you have to have it sent off and rebuilt.

Anyone know where to get a computer at? tried all the local auto parts stores and all of them say they cant get them.

 

Are you needing the PCM or IDM? The idm is the one on the drivers fender under the hood.

 

I assume the PCM, it came out of the firewall at the driver side fender.

 

Its not the Injection module its the actual PCM. no one seems to have it

 

Ya that would be the pcm. Usely the idm is the one that gets water in it. But i have heard of the pcm getting wet if the windshield leaks.

 

Yea, doing some re search online looks like i can get a remanufactured one for 500+ or get a used one for around 300....


if it helps anyone on pointing me in the right direstion it is F5tf-12a650-bjf

 

also while searching on here i seen in a old post that you could put a 97 model in the truck, is that true? will i have to do anything fancy to make it work?

 

Yes, a 97 auto PCM will work just fine.
Why do you think the PCM is dead .. had to ask?

 

guy working on it had issue's with it, every time you try to read the code's it tells you to turn the ignition on and it already is, pretty much no communication with it. Think he said it finally did but forgot what he said it said but it was something to do with computer, also we found that the fuse for it had foil in it, plus it has been wet and is rusted/corroded

any certain code i need to look for in the 97 truck's?? will it have to be re flashed or will i be able to plug and play?

 

and is the 97 the only one that will work? or is it just the best one to upgrade to?

EDIT: just found the thread again, and it says aslong as it's for a AT and std emis it will work??

so bassically a F7TF-12A650-TA or a F7TF-12A650-TB??

 

What kind of scanner was he using? Which fuse had the foil on it? Was it the number 22 under the hood? How is the fuse for the 12v power outlet in the cab?

 

Im not positive about any of it, but i know he is a diesel mechanic and has been for many year's.

 

Im just wondering if the 22 keeps blowing, check the fuel bowl heater.

 

Test the lighter fuse in the interior fuse box.

 

Here is the deal on what might be happening. Fuse #22 (under the hood) provides power to the computer and the fuel bowl heater. If the fuel bowl heater shorts out, and they do, it kills the fuse and the result is no power to the PCM. One way to check is you won't the WTS light. If that is the case then unplug the fuel bowl heater, replace the fuse and try to start.

Not saying you don't need another PCM now or in the future but this may get you going, or not ...
