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

Oil metering pump is the pump that delivers oils straight into the housings via manifold for seal and rotor lubrication.

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.
