My vehicle has good compression on all 6 cylinders. However, the three passenger side cylinders have no sign of combustion. Replaced fuel filters as well as rails and injectors. IAC valve. TPS, MAF, I'm replacing crankshaft position sensor tomorrow. Help, I'm stumped.

Are the fuel injectors getting a trigger signal from the ECM? Also, with the key on there should be 12 volts at one of the wires to each of the injectors, they use a ground to close the circuit form the PCM.

Here is a guide that can help you test what I am talking about:
