P1353 and P0353 fault codes. Ignition Coil B - Primary circuit fault/ Ignition Coil C Primary/Secondary Circuit. Engine cranks but wont start, changed coil pac, sparl plug wires and fuel filter. Checked timing belt too,Does have spark, I used a spark tester with each plug wire and they all had a good spark. has fuel and compression. Could the problem be the ccrm or pcm and if so how to test?

 

Hello and good day to you:

Rescan, there is no such fault code as P1353 for your indicated vehicle.

Perhaps it was a P0353 which would implicate the #3 (or "C") COP, not #6 which should give a P0356 DTC.

Each COP has two wires: A RED/LT GRN one that has switched battery power (VPWR) on it and a second wire that goes to the PCM that, when switched to ground by the PCM, fires the coil. If there is an open circuit (or other circuit fault) anywhere in the COP's supply or signal wiring or in the COP or its connector, you will get a P035X DTC where "X" is the cylinder that has been identified as having the fault.

While there is an input to the PCM from the AC system, it is not related to the ignition system.

If the fault is indeed with #6 (second from front, driver's side), check for supply power at the COP's connector, then perform a continuity check from the other connector pin (ORG/YEL wire) to PCM pin #1. Verify no short to either VPWR or ground exists on that signal line. If the entire circuit is intact with no faults and the COP itself is neither open or shorted on the primary side, then the output driver in the PCM has probably failed.
