    Oil Pressure Switch for Fuel Pump - Strange Happenings

    After at least 15 unsuccessful tries at starting it, I went to do something else. 30ish minutes after my last try and having done nothing new to it, I tried it again and it started right up. I let it run. Turned it off. And, it started right back up. It has got to be a short somewhere, or could...

    Oil Pressure Switch for Fuel Pump - Strange Happenings

    Thanks. When I was just troubleshooting it occurred to me that it is doing exactly what it does when you try to start the boat while in gear. So I played around with all the wires while turning key but it didn't work. I will check out that other thread. Thank you.

    Oil Pressure Switch for Fuel Pump - Strange Happenings

    So all was going great last week. I ordered the relay that was suggested. The boat has sat for a few days. I just started it right up. Then I turned it off. And now, it won't turn over. I turn the key the first click and all gauges read fine, including the amps. However, the oil pressure gauge...

    Oil Pressure Switch for Fuel Pump - Strange Happenings

    Thanks for this too Rick. These wires were dangling out there in plain sight. On another post someone mention a purple wire and a purple/yellow wire that lead to the switch. They were right there in front of me so I attached them with a jerry rigged coupler. I hadn't done anything between my...

    Oil Pressure Switch for Fuel Pump - Strange Happenings

    Thanks Rick. I am a real novice but I have enough gumption to do anything provided I have a great diagram like the one you provided or a YouTube video. That said, could you provide specifics about the inexpensive relay? I have no idea what that is. Thanks man, Doug

    Oil Pressure Switch for Fuel Pump - Strange Happenings

    I have a 1996 Mercruiser 4.3 LX Gen+ in a Donzi 182 Medallion (bowrider) that has been working great since I have owned it, which has been 2.5 summers. Yesterday, after running great for about 20 minutes, it stalled. After that it would start really well but then sputter out after 30 seconds to...

    4.3 engine stops running. Fuel pump?

    Thanks for the reply Chris. And sorry about hijacking the thread. I am not a frequent user of forums and I thought that keeping it within the topic of oil pressure switches would be more efficient than starting a yet another thread on oil pressure switches. I will continue this conversation on...

    4.3 engine stops running. Fuel pump?

    Do you have any idea why someone would have bypassed the oil pressure switch? I got here b/c I was have the exact same issue as watrski4ever. When I went to look at the oil pressure switch I saw that it was rigged so that the purple wire and the purple/yellow wire were taken off the leads and...
