Pretty sure I have an Ignition problem. I have 41 psi in the fuel line. ALso the injectors were new last year. I do NOT have a spark in the coil wire or any plug wires.

Just completed the following ..... but still have the problem....

checked all the codes in the computers again, CCM 1.2, 1.3, 1.4. all these settings are normal and indicate the CCM is communicating to all the sensors correctly. In 1.3 mode, I could see the CCM turning on/off sensors/lights. So this tells me the CCM GROUNDS ARE GOOD. Also verified again there are no stored DTC codes in the PCM/ECM/ABS/TCS/DERM.

All my grounds from the PCM are good. Pulled the PCM connectors off, connected the test light to each ground pin and light came on.

Also did a continuity test on the Opti 4 wire connector back to the PCM:
B2 - Low Resolution Signal Input was 3.4 ohms
B3 - Distributor Reference Low Signal was 2.0 ohms
B14 - Distributor Ignition Feed was 0.6 ohms
B20 - High Resolution Signal Input was 0.8 ohms

I can't find anywhere in the SM that tells me if B2 and B3 should be that high....ANYONE KNOW????

According to the SM, I still need to test the following which causes a crank no start:
B2 - Low Resolution Signal (but this should set DTC 16)
B3 - Distributor Reference low signal (No DTC set)
B5 - Ignition Control (should set DTC 41 or 42 and I installed a new coil an d ICM so can rule this one out)
B14 - Distributor Feed (No DTC set)
B15 - PCM Battery Feed (No DTC set and has something to do with the Oil pressure switch)
B30 - PCM Ignition Feed (No DTC set)

The test for B2 is "TEST CONNECTOR 'A' DISTRIBUTOR 'A' " and B3 uses "D"..............IS THIS JUST A CONTINUITY TEST??? Same as I did above?

Also rechecked all the DTC's .... nothing

 

well I am giving up and sending the car to a dealer. I can't do anymore diagnostics without a Tech1.

 

You probably don't have AC voltage at your ignition module connector. This is the low resolution signal. If this is not present you most likely have a bad connection at the opti or the sensor in opti not working.

 

You have done some good diagnostic work and I hate to think you have to take it to stealership.

Did you check for spark DIRECTLY from the coil output terminal to ground ??
-If spark --> Opti (heck, maybe the 2 screws from the rotor came off)

PCM(determines timing in 1 degree increments from Opti High resolution) --> ICM (timed ground signal received from PCM) --> Coil (primary grounded, secondary discharges high voltage)--> Opti(receives high voltage, transfers to correct cylinder via rotor position) --> PCM(Opti sensor feedback, low/high res, adjusts rich/lean per conditions of O2 sensor)

I think you are close....real close.....

 

You need to check for pulses from the pickup coil that goes to the spark module. Diagnostic manual should also have you check the resistance of the pickup coil. If you don't have pulses, then the spark module does not pulse the primary of the spark coil and therefore no spark!
