Hello my name is Mike and my wife and I are not new to boating but new to the yachting side. We have a 1996 320 voyager with twin 350 crusaders. We are frustrated at the moment due to the starboard engine dies randomly. Here is what I have done and found so far, installed new OEM electric fuel pump, new OEM anti syphon valve, new ECU unit. On to the trouble shooting part, at this time I have wired in a green light from the ECU to the fuel pump so I know when it looses voltage. Once it looses voltage you can turn the key off for a minute or so and restart the engine just fine, it may stay running for a minute or the rest of the day. At this time I feel like the problem is before the ECU and that's where I need advise on what to check next. I have cleaned what grounds I can reach and wiggled what wires I can reach as well, I keep hearing people comment of fuel and ignition relays but I can not fine them. I want to say thank you in advance for your all's help.
