I have a1998 Shamrock with a Seamax/PCM GM 5.7 Liter engine with EFI/TBI. The boat willnot start unless I pour fuel directly into the intake. Prior to it not startingwe were idling or running at low speed in the bay when the engine stalled andthen restarted immediately on 3 occasions. On 1 occasion the engine did notrestart immediately, but restarted after several minutes. The next time I tookthe boat out I had no issues at all and I could not get it to replicate theproblem. When I went to take the boat out on Saturday the engine would notstart. I am getting no power to both the electric fuel pump and the fuelcontrol cell. All fuses check OK. The relays are firing. I am thinking the ECMhas failed but not sure and with the cost of a new ECM I want to be sure orconsider other options. Any ideas or help would be appreciated.
