I transplanted 1999 Ram 1500 5.2L and 46RE along with the engine harness & PCM to a 1940 Chrysler Royal. I did not take any of the emissions stuff.

I merged the 99 engine harness into a 96 Dakota 3.9 Harness to get all the fuse box, lights etc. This was a lot of work!!!

So, the engine starts if we dump fuel manually into the throttle body and runs as we spray fuel into TB.

The ASD relay is not seeing power on pin 85, and I suspect same for the fuel relay. And so no fuel signal to injectors and no fuel pump.

I think this would be due to PCM not seeing the Leak detection pump and other emissions stuff?? or????

Maybe I need a PCM for hot rod application?

Thanks in advance, Mike
