Injector #3 problem

[hers1via]

I have just installed my new 440cc injectors with s-afc. The problem still exists. Injector#3 wont fire up. I had someone look at it and said his conclusion would be the ecu. He checked the compression on the cylinders and they are okay. Would can it be?

getting juice to that injector? Switch the plugs around. If it will reach try plugging #3 plug into #4 injector. I suspect the problem will follow. If it does either there is a short in the wire or the driver in the computer has failed. You will have to start at the injector plug and work back towards the computer until you figure out which it is.

The dropping resistor is much more likely than the ECU. Do you have 12VDC+ at the solid colored wire.
