OK I am back with more questions.
I got everything up and running with no error codes. I have a 7747 ecm with a chip done by Dave W. stock except 700r4 and smog removed.
now it runs fuel pump for 2 sec gets crank signal but does not turn on fuel during cranking, If i jumper prime connector to 12v it will start and run with jumper removed once it starts. when idling it is good but sometimes will backfire if throttle is open and closed(reved). when driving it is very doggy slow acceleration and some backfiring. the only code I have seen is 33 and 42, but cleaned the pins with contact cleaner and haven't seen a code since. So what do i need to look for?
