No Spark, and no screen.

[Justinb917]

Trying to help a buddy with a 2015 P500 that was flooded and left for dead for about a year. The starter engages good but the plugs not getting spark, neither is the ignition coil. I took a multimeter to the fuses and all have 12v except for “Ing” which I’m guessing is ignition. Read the other form about the 700 with no spark and no screen but my screen is dead and stays dead. Any idea what the issue is or have any advice on how to pin point it?

The ignition fuse gets power from the Self Management Relay. That relay is triggered ground by the ECM.

That relay is fed power from the "ES" fuse. If that relay isnt working, the display will also be dead, along with the coils.

So if that relay test good, and is getting power on both Red/Blue leads the ECM must not be grounding the pin to make it work.

You can bypass it temporarily by shorting the Red/Blue wire to the Black/White wire. The coils and display should work then.
