Hey all, My First post here on IBoats. Thanks for all the info everyone has provided me over the years and have saved me from posting stuff by reading others problems and resolving them for myself. That being said i have read many posts and cant quite find an issue like mine and hoping to find some insight.
I have an issue i am working on and would like some assistance. I have a 2006 4.3 GL that will not start. Brought it up to the garage and determined that there was no fuel getting to the carb. I pulled off the fuel pump wiring and put my Multimeter pins into the contacts. Cranked boat and no power to the contacts. I proceeded to test the Relay checking OK. I then checked the fuel pump fuse and the 7.5 Amp fuse is OK. After this i ran a positive and negative from the battery to a connector i made and put it directly to the fuel pump, Fuel pump runs OK. I ran the pump Manually for 15 seconds or so and filled up the dry Carb Bowl. I started the boat to see if it would run and it started up and ran. Once the boat had started the starter stayed engaged (12+ volts going to it) not bendix sticking. I proceeded to shut the boat off when i heard the starter staying engaged and the ignition would not work, next step pull the kill switch, It neither worked. Ran to the back and pulled the coil wire to shut off the engine. With this issue determined i started searching I boats forums and found lots of alternator related issues and diode issues. What i have done is pulled the purple off of the terminal on the alternator and started the boat. the boat will still not shut off and starter stays engaged. My volvo book i have goes to 2002 but i have been hoping the wiring diagrams for the GL i have been looking at would be the same in 2006 as 2002. Anyways has anyone had this same issue? After looking at the diagrams i see the fuel pump is fed from the YW/RD Start circuit wire on cranking and then the alternator feeds it after running. That is why i assume back feeding through the alternator keeping the start circuit energized keeping the starter on. still cant figure out why my motor stays running as the purple wire disconnected from the alternator should prevent the back feed to the energization of the coil and ruins my theory. However If i manually run the pump to fill the carb bowl then pull my fuel pump relay and start the boat it will run fine and the key shuts off the motor and the kill switch functions properly and the motor runs fine until the carb is dry that is. Any ways i have some time this morning to run some tests and i am going to do some diode tests and check around for more issues. I tried to be as detailed as possible to help with the diagnosis. Thanks guys. Josh
