Hi all..anyone know if the asd output voltage changed between a 90 tbi sbec and a 94 tbi sbec.......My 90 tbi car ha a 14.5lbs fuel pump and the 94 had a 39 lbs pump......I put the 94 sbec in the car and it runs great except I get a code 42 for auto shut down...with no symtoms at all besides code when I do the key on off 3 times test... Anyone think maybe the driver in the 94 comp is pulling more voltage to the pump and or the fuel pressure regulator than needed ... remember I only have the early 14.5 lbs pump not the later 39 lbs pump the 94 comp was designed for...I also reset the comp and within 10 minutes the code 42 came back and the car still runs fine????????
Thanks for any help
