I do not want to be rude and I doI appreciate your time, However it seems to me that you evidently you do not kniow the answer to my specific question, because you keep trying to tell me how to diagnose the problem. It has no codes. I understand in order for a gasoline engine to run properly it needs air, fuel, compression, spark and to have all of them in the correct timing. With that said, the following things have been verified, It has 210 lbs. Of cylinder compression, the valve train is is in time, the crankshaft & camshaft sensors are new (I tried the old ones just to make sure the new ones were not bad) Every coil fires, all plugs are new and working, The air intake is clear and unobstructed, the intake and exhaust valves are operating properly. The fuel pump is new and has the correct flow and pressure. All wiring has been checked with an ohm meter for continuity between each connector and the PCM plug in. All ground wires have been verified per the ground distribution wiring diagram and with an ohm meter for continuity to gtound. Every injector is operating and has a good spray pattern. With the upper air intake off, when cranking the injectors all spray at the same time, not in time with the cylinders. I am trying to verify that this is not correct, If it is not correct, then I feel confident that the PCM needs replaced. I know it would be a very strange coincidence for the PCM to go bad, I understand the concept if it worked before I worked on it, it probably something else, however I feel confident that I have checked evrything else.
