    ECM problems

    My 2007 196 Excalibur 330 engine has been having intermittent issues. Engine stalls and low pressure fuel pump keeps running even with key off. It will not start. If I tap the ECM the pump stops and you can hear the throttle close. Then the engine will start. One of those times the cylinders 1 and 3 filled with fuel. It will then run for several slalom sets before any problems happen again.

    Get it to someone that can connect it up to a computer running Diacom to see what state the ECM is in and what it thinks it's inputs are showing.
