SOURCE: pcm is not grounding injectors. need a pin diagram and ground location diagram

Ground points are in different locations throughout wiring harness. If you had any work done to engine it is very possible to have missed one of the grounding eyelets during the process of putting things together. Check along wiring harness in any area you can see or reach to try to locate any loose or disconnected ground looks.

From the battery to the frame. Follow it down from battery. Then there should be 1 or 2 braided lines from the frame to the body u will just have to lay down & look around

Secondary fan on impala SS 1996 not operating. fan motor works, new sending unit, new relay installed What else could keep it from coming on?

The PCM controls these fans via certain sensor inputs, ( CTS ) and switches ( A/C compressor for instance ). When relays are removed, both relays sockets should show 12v constant ( battery voltage on "switch side" ). When the key is rolled on, there should be 12v appear in two more places, ("Coil side" ) the relays are then operated by a ground signal from the PCM. ( Powertrain Control Module ) You need a scan-tool to check for fan request, by the PCM. A/C compressor request, etc. If you have any DTC's then repairing them may well fix your problem, otherwise, you may have a faulty PCM.
