Just bought an 89' 2WD with a Banks intake, intercooler and full 3'' exhaust for $900! arty018:. The guy had the injection pump rebuilt and said that the timing may be off because he installed it himself. The lift pump is disabled and the fuel is being supplied by some kind of custom electric pump which I will disable and use the lift pump. Main question; How is the correct setting for the timing achieved on the injection pump? I also need the wiring diagram for the ignition circuit because a push button is being used to bypass it if anyone has one it would be very helpful to me. Thx!
