check engine light #20
OK I retrived code #20 AKA metering oil pump MOP position sensor
basic fuel injection and fixed timing.... So what should I be looking at?
this is the last of a series of check engine lights, my 1991 rx-7 does start but dosen't drive if I try it stalls out.. I can get in and oout of my garage... ok so here is what i did that could be the cause, I installed the APEX-I AFC and messed up ny wiring harness I think everything is streight now, I ran new wires and pin conecters, but I still think that maybe it's in the wires, I no longer have the AFC installed I just wan't it to work normal first. Any thaughts and or sugestions are apperciated
thanks Marco

OK, this code is related to the 3-wire connector on the OMP. The connections are, left-right on the OMP plug, E2 (ground, ECU connector 3D, Brown/black stripe), VC (voltage, ECU connector 2I, Brown/white stripe), VO (signal, ECU connector 2A, Green/Black stripe). VC-E2 should read 1-2Kohm. VO-VC reading + VO-E2 reading should be 1-2Kohm. If not, OMP is bad. Otherwise, check wires from OMP to ECU. Good luck.
