I recently bought a boat with a 99 350 MAG MPI / BRAVO 1. Engine had head gasket issues and engine was already partially dismantled. I replaced both gaskets and completed the engine.
Engine is not firing up, no ignition (no spark at the plugs)
I can hear the fuel pump working for a couple seconds when turning the switch on.
When switch is in “on” position, I have 12V at the + side of the coil (red wire)
But I also continuously have 12V at the negative side of the coil (white wire), (not only when switch is on, but also when cranking)
At the distributor, only 2 wires; white/green which is connected to purple/white and red/white which is connected to pink wire.
What’s the problem? How to test the distributor?
Anyone an electrical scheme?
