The CPS harness is shielded. You already know that.

What I was thinking is: verify that those CPS wires are correctly connected. If 2 of the wires are not connected to the correct wires, you might get a RPM signal on the tach, but the overall signal to the computer could be incorrect.

The fuel pump relay gets its ground (in this year model car) from inside the LH. I have had 2 LH computers that had to have the fuel pump relay jumped to get power to the fuel pump. I drove the Stepson all the way to SITM with a fuel pump jumper (switched). It ran great the whole way.

I will almost guarantee that you will not get fuel through your injectors unless you clean them ahead of time. Gotta love that corn syrup residue left by Ethanol.
