I have a 95 Barchetta 182 with a Merc I/O. Suddenly today is started but only ran a few seconds. I have traced the issue to the fuel pump wiring. The is NO voltage to the fuel pump. I believe it does not have its own fuse but I am not in favor of "hot wiring it". I can't figure out where the voltage should come from. Thanks for any help someone would have.

When the key is in the start position it comes from the starter solenoid, when in run I believe it comes from a distribution block back by the distributer. I had issues with mine and it was a bad starter solenoid. If you upgrade your membership you'll get access to wiring diagrams and a bunch of other information that's well worth the money. They're what I used to troubleshoot my issues.

Just noticed you're a silver contributor. You should be able to find diagrams in the mercruiser engine section.

I did get the boat up and running. Thank you for the help. It ended up that the fuel filter was plugged. Not visible at all by looking at it. I do run gas with ethanol, so it probably needs to changed once a year. I made a jumper wire to pull the gas up without cranking the motor forever. It took about 2-3 minutes to get primed and pumping.

One last question, I could not find any mercruiser wire diagrams for my 443B model engine and out drive. Does anyone have a link to a good schematic?
