There is a long story behind this... but I continue to have issue with the dreaded P1222 code and 10 chimes. It all started after I rebuilt my engine. All was going well until I soaked my ECM with oil and had to replace it and the wire harness. Now, every time the engine is warm and I'm cruising down the road and I let off of the throttle, ding, ding, ding.
I've done the return flow tests, they are high. So I checked all the connecting tubes and they are all fine. Been verified many times. Sent the injectors back to Industrial Injection, they tested fine. Drove truck to I.I., they checked everything and can find nothing wrong. Injectors and tubes are perfect they say.
I replaced the II injectors with brand new Big Bang stockers. Same issue. Nearly same return flow rates. 19ml/30 seconds at idle, 300ml/30 seconds with the FCA disconnected.
Here are my questions:
Is this return rate too high?
Am I overheating the fuel in the tank with this high return rate and making the problem worse the longer the engine runs? Because it does get worse the longer I drive it.
Is there something in the new ECM programming that is an issue? I had Dodge check the program to make sure it is the latest and greatest.
I have replaced darned near everything. It is a stock truck with all stock replacements. No tuners or tweaks. Stock. I want to know how hard I need to push back on the injector people, or if I have a software issue.
