Thread: No start, no injector issue.

    Default No start, no injector issue.

    Having an issue with my Holley Dominator EFI. It's developed an issue. If shutting off while warming up the car, it won't restart. Holley cam & crank sensors with CNP. Car is on M5 with a Waterman cable drive. I've verified it has spark with a spark plug grounded. Unplugged the injector harness and the two red wires have +12V at crank. I tried a noid light and it does not light up. It will see cranking RPM with the laptop in live view. Where should I go from here troubleshooting? Thanks in advance.

    On my Dominator EFI setup, I have a fuel & oil pressure sensor that must have signal to start as well as over 400 RPM. Can you check if you have that?

    You need to start with the basics and confirm all of your wiring is in good shape, and everything is connected to where it should be. You can also run a System Log to check your cam and crank signals. You said this is an M5? BMW? What engine? Andrew
