98' PCM GT 40 Wont start

[jimlahey]

Here is the situation:

I am starting the boat up for the first time since it was winterized last fall. The battery had a low charge, so I charged it to 12V. Upon bringing the boat to the lake, the engine turns over but will not stay running once i release the turn key pressure. Once i let go of the key, the engine dies. The engine kill switch safety latch is engaged. There is a depressable button at the bottom of the throttle lever, is that part of a choking system? I can also hear a short buzzing sound once i turn the key into accesory mode, which i think is the EFI. What might the problem be??

Any help would be greatly appreciated.

RE: 98

The buzzing sound I think will be your fuel pump. Try changing the filter in the fuel control cell. Not a major project but can be a pain. That filter seems to cause a lot of not starting issues if it is dirty/clogged. I think I would start there since it's a pretty cheap fix/repair. Plus it should be changed every so often anyways.
