Re: how to tell dpfi and mpfi TO obd1 jumpers apart
There is no such thing as a DPFI to MPFI jumper. You do that on the OBD-0 vehicle harness ECU plugs. If it was DPFI you have to add the 2 injector wires, and the 2 wires for the crank sensor. It sounds like you crossed the wires for the distributor to be getting a code 9. So the only jumper I assume you have is OBD-0 to OBD-1?
