I’ve been having an issue where the car randomly stalls. At first I thought it was the new fuel pump (hellcat 525) since it started happening after I installed it.
Today, I had the key in the on position and while I was turning the crank by hand (plugs were out) the fuel pump turned on and off.
I’ve read this thread https://www.dsmtuners.com/threads/1g-basic-ecu-mpi-circuit-function.435961/
So I have a feeling it’s my black top cas. I unplugged it and turn the engine over again and pump didn’t turn on. As soon as I plug it back in, the pump turns on and off which I’m not sure is normal. Could there be a short inside tripping the mpi relay?
It used to take some time before it stalls but now it does it within 5 minutes of starting. It starts right back up no problem.
