What PCM do I have?
Have an handfull of oddball problems on a 94 k2500 Suburban and Id like to snag a PCM or 2 from the scrap yard for testing purposes.
The current PCM in the truck has no serial/part numbers aside form a crusty sticker that I can make out EM7427.
What all other PCMs could I use in this truck? I know I need to change the chip (PROM?) out.
Is there a way to validate the chip in the PCM now is for that vehicle? I wouldnt put it past some fella before me to install the wrong components the way the truck acts.
Thanks in advance!
