Hi Alex
New test results including engine running.
I made some new test connectors and this improved the sensitivity. Retested all circuits pertaining to CKP/CMP/ICM/PCM for shorts/open circuit and nothing was out of tolerance or obvious.
The car has also sat for 2 days while I traced circuits and had the ICM tested. I also pulled the PCM and it sat for the same period disconnected. Removed the cover of the PCM looking for obvious burns or loose connections and also found nothing.
Today I reconnected all components with the exception of spark plug wire #2 and injector #2. Attached spark tester to #2 wire and test light to #2 injector connector and placed both where I could see both easily and clearly without moving my eyes from the drivers seat.
Started the engine and took it up to 2000 RPMs and held it steady for
4 minutes (a new record), at 4 minutes there were a couple of small misses then they became more pronounced and longer. The spark tester stayed steady and the injector test light would fluctuate in conjunction with the misses, but I had to be paying very close attention to see the differences. When the stalling started the spark tester was steady and the fluctuation in became more obvious, then the car died.Ran the KOEO and DTC came back 111, 10, 111. System pass.
Restarted car within a couple minutes of dying and it started right up. Took the RPMs up to 2000 and ran that way for 4 minutes again before the missing started, but this time the misses were a little longer and the injector test light was noticeably fluctuating with each miss, but the spark tester was steady. Then it died at 4 minutes
30 seconds, same as before.Ran the KOEO and DTC came back 111, 10, 111. System pass.
Tried to restart and no luck, BUT.... this time observing the spark tester and injector test light the difference was great. The spark tester was steady and the injector test light only lit intermittently and each it came the engine would catch briefly and no start.
Ran the KOEO and DTC came back 111, 10, 111. System pass.
Fuel pressure was good and engine temp sensor is new. Timing wasn't tinkered with at any time. Next step is the library and get relevant info. In light of my new testing procedure does any of this yield new insights. Even though the 211 Profile Ignition Pick-up code hasn't reappeared it still is very relevant as it has to do the communication between the CKP/ICM/CMP/PCM and the PCM controls the injector activation. The CEL has not come on either.
As far pulling the CMP and having it tested I will have remove a bunch of stuff, as in all the way down to the lower intake manifold. I know I'm going to have to do that and will probably have to do it next (and soon) if nothing improves.
I'm going the library to use the 'Professional' books to see what I can find.
Thanks
Jim
