dude, didn't you just make a thread in which this was answered?

Not so, every EEC-IV wheather MAF or SD uses pin 22 to trigger the fuel pump relay. The MAF EECs do use a feed back circuit(pin 19) to tell the EEC that the F/P is receiving voltage. What happens if you don't connect it??? NUTHIN', the EEC sets code 89 in memory, and life goes on(in other words it will run just fine).


is your car not running, or have you even tried running it yet?
