12 direct battery input
33 open/shorted a/c clutch relay
54 no fuel sync detected
42 open/shorted auto shutdown relay
I know i need a new fuel pump, no problem there. and from what i gather the error 12 will always be there. as for the other three..i have no idea how to fix at this time. i have been looking around but just havent found the answers i am looking for. could someone help and give me straight forward ideas.
12 will always be there
33 means you don't have an air conditioner installed (not a concern)
54 means your fuel pump is shot
42 your auto shutdown relay is shot, its under the hood in the relay box, I think.
