So reading through the threads it looks like I have my problem boiled down to 1 of 3 issues, however I'm not sure on how to go about checking each item. Per a thread Don S worked on regarding fuel pump issues it's came down to this:

1.Connection at the main engine harness is bad.
2. Bad neutral safety switch.
3. Bad connection between the ignition switch.


Forgive me if I sound lame, but can someone help me out with how to diagnosis these 3 issues please. I'm not sure where to begin.:confused:

What are we working on? Full model number or serial number is needed.

NOTE: The neutral safety switch has nothing to do with fuel pumps.

Hello Don and thanks for the quick reply. I found the 3 what to check from the thread http://forums.iboats.com/showthread.php?t=166006 but I'm unsure how to check those?


Volvo Penta's 4.3 gl sx v6 vortex
Serial #4111641363
model #3868845
type = sx-mlt

I followed all steps on the thread to come up with the conclusion it's one of the three mentioned above

Still don't know what model engine you have, the serial numbers are for the drive. The 4.3GL is only the first part of the model number.

Have you looked at the stickies at the top of this forum? Lots of information that you are looking for are in those stickies. That's why the are stuck to the top of the forum.
