Truck has not started in about a month. She tries to turn over but does not fire. I only put about 1000 miles a year (dump runs etc..). I think some mice may have messed with the wiring. I am not getting any spark. Had it towed to local Ford garage, told me I need the computer replaced (installed $700). Two questions, can I replace the computer with a used one from a truck boneyard? Is this something I could do my self?

 

one bolt pulls the harness it is mounted on the driverside firewall

 

check ebay

engine computers for a low as 120.00 u.s

 

thanks - will it require reprogramming by a ford dealer?

 

it should not need reprogramming

if you order the correct year/engine

 

The computer has part number/code on it. Get the same one and your good.

Its just above the engine on the pass side. It sits in a little shelf with one bolt on the wiring harness and two bolts holding it in place.
