hello everyone,
I have a 2002 MB Sports 190 Inboard with the PCM 350 Chevy motor. Its fuel injected with a throttle body and has 786 hours.
Last Friday night my buddy and I went skiing and I pulled him with no issues. When it was my turn, the running engine stalled and he could not start it again.
We pulled the air cleaner to see if fuel was spraying on engine cranking but it was not.
So we got towed in and on Saturday I went about troubleshooting. First I added fuel in hopes that maybe my fuel gauge was stuck at 1/2 and I was out of fuel. But it wouldn't start.
Then I checked the fuses at the rear of the engine and both the 15a for the fuel pump and 10a for the ECM were blown.
I pulled the fuel pump relay and it ohmmed out perfect.
I re-inserted the relay and installed new fuses and it started and ran fine. I took it around the lake for the next 1/2 hour with repeated stops and starts and there were no issues.
Since I know that fuses don't blow for no reason, I think I need to troubleshoot further.
And I think I might replace the fuel pump (in the fuel control cell) and/or the low volume fuel pump.
And I'm still confused why the ECM fuse would blow IF it's a fuel issue.
Thoughts please.
