Ok I was driving pulling a toy Hauler. Then the truck just died. I had a spare CPS and replaced it and it still did not run. I thought it might be the IDM again so I changed it out with a known good one from a running truck also swapped it and mine works also. I bought another CPS and it still not working. I have an AE and found no new codes. The ones that are in it come and go. P1209,P1211 and P340. I have cleared them and still it will not run. I did a buzz test it was ok. Any ideas.
