injectors not working any help appreciated
I have an 85 32 v, I fried the oxy sensor wires by reusing an old sensor.
Got a new sensor and re wired it now I do not have any power coming from the harness pin on that connets the sensor and the injectors, The new ground for the oxy sensor was run to the fuse panel ground instead of back to the injectors. Does anyone know if that ground wire needs to be put back up to the front of the firewall where it came from? And where exactly does that ground go to on the engine? I have pulled the fuse panel and checked for continuity and everything checks out fine. If I touch either injector wire to a hot pin the fuel pump works. The relays have both been replaced for the fuel pump and the ignition.And finally but not least the fuel pump will run intermittantly (sp) when the key is turned on.

These schematics show the O2 sensor wiring.
The Oxygen Sensor is powered by the fuel pump relay XX - the circuit runs from relay pin 87 to central electric W13 and then to the blue wire that goes to the Oxygen sensor.
The ground is the brown wire and goes to MP VIII.
The signal wire is shielded, and runs to LH pin 20.
