It sounds right.

I want to see if I understand, you said you did the test and it was all good. During the test after thetest light flashes momentarily, (the PCM grounded the ASD relay) you then went on to crank the engine. When you crank the engine,(after waiting for the test light to flash once, this must be done), what happened?

1. If the test light momentarily flashes during cranking, the PCM is not receiving a camshaft position sensor signal.

2. If the test light did not flash during cranking, unplug the camshaft position sensor connector. Turn the ignition key to the OFF position. Turn the key to the ON position, wait for the test light to momentarily flash once, then crank the engine. If the test light momentarily flashes, the camshaft position sensor is shorted and must be replaced with a new one. If the light did not flash, the cause of the no-start is in either the crankshaft position sensor/camshaft position sensor 8.0 volt supply circuit, or the crankshaft position sensor 5 volt output or ground circuits.

3. If it is constantly flashing, this is the fire signal to the coil pack and you should be getting a spark. If this is the case, ensure the pins on the coil connector are not spread (or dirty) so there is no interferance with the signal. If you still have no spark, then either the coil pack is bad or theres not enough power to the coil pack.

let me know 1, 2, or 3 and we can try to isolate it down.

PS, the picture I added at the bottom of the post was for the failure to start test, I couldn't get it to upload last time.

I can tell you that its not 1 or 3 for certain. The light doesn't flash at all, its on constantly. I'm pretty sure that its the same for 2, I know we cranked w/o camshaft sensor for 15 seconds as to try and get the PCM to override not having a Cam sensor signal and go to default and start (something a chrysler tech that we know told us to do) and I think that the result on the test light was the same. Plus,we've got the 8 and 5 volts at each of the sensors like we should, and no codes.

Ok then, prior to the spet 1 I mentioned above, the light never "flashed on once", it only stays on? Also, are you tyring this procedure with the probe to ground (like the picture) or to voltage (as mentioned by ...?)? Please tyr it the way posted if you haven't yet done so (to ground, not voltage) and let me know the outcome.

If the light is always on with the correct configuration (never pulses), you will not have a spark, and you need to start breaking the circuit at diffrent points to detrmine where the short is (it sounds like a short to a voltage, not a ground). If we can isolate where, all you will need to do is run a new wire (even outside the harness) at that segment to correct the problem.

no blinks at all, just on constantly, and we know thats why we dont' have spark, we're not getting pulse. Thats why we thought we narrowed it down to ICM in the PCM.

You think its a short to power? We've tested the wires with the light hooked up to power and ground, dude, we've tested these things a million times in every way you could imagine, I've forgotton some of the results becuase we've done so many. We've tested, and retested numerous times. We know we don't have short to ground, another guy never said anything about short to power, he was just looking for short to ground. We've done all the procedures AllData gave us, we've done some other tricks chrysler techs have told us. Everything is okay except we're not getting an ignitino pulse.
