I'm still having problems with my injectors. I have low impedence s4 injectors, that are brand new btw, that I am using on my S5 high impedence harness. I spliced some resistors into the harness.

I tried testing the voltage at the ecu pinout and got 2-3 volts only on all 4. I know it's supposed to be 12v. Anyone know what may be causing this? As you can imagine the injectors are not shooting any fuel. I have fuel up to that point however.

Any help would be appreciated. I think this is the only thing keeping me from getting this beast resurrected.

Remove the resistors and see what happens. Voltage wise that is. You are not going to ruin any thing if you do this and just idle/run at low load.

ok. Should it at least start even with the low impedence injectors? Any idea if there is any other reason for such a low voltage readout?

I tried that again and I'm getting 12v at the actual pins on the back of the ecu. When I test the harness and the injectors I only get like .3 volts not 3 like I thought before. What should I do next?
