Help with PCM part number/calibration code
Long-time lurker, trying to get my brother-in-law’s 1991 F-150 4.9 4WD M/T healthy again. He has no spark, and I’ve replaced ignition coil, ignition control module, and checked to make sure the dizzy is spinning. On to the PCM.
His was replaced at some point in the past, so the sticker is scrubbed out, so I just want to verify I am getting the correct one from Rock Auto. The calibration code is 1-51H-R00.
I have searched the forums every which way to find a match and couldn’t, so I would appreciate any help y’all can give. Thank you!
Brian
