Help! I have a 1994 5.8L Pro Boss with the Pro-Tech Injection system (throttle body injection). The boat will start and then die after a minute or two. I just put the boat into the water after taking it out of winter storage. My summarizing routine is to change the oil, oil filter, gas filter and spark plugs (gaps checked).
My first thought was that the gas went bad so I added 6 gallons of premium gas (to bring the tank to full) and added a bottle of HEET and a half bottle of Sea Foam. I removed the gas filter and emptied it to see if I had water and I did not have water in the filter.
Normally, with my engine, when I turn the key to on, the gas pump cycles and it normally squirts gas into the carburetor, it does not seem to do that anymore. The only way I can get it to do that now is to turn the key quickly to start and all four injectors begin to squirt gas into the carb. It takes me a couple of times doing this to get the engine to start.
Once the engine starts, it idles fine, everything sounds good, purrs like a kitten for like I said about a minute or two and then it just dies. The injectors fire gas continuously. (One note, the carb flaps never open unless I rev it.)
I’ve done a visual check and everything looks good, all of the connectors are tight, spark plug wires are snug on both ends, metal air filter is clean.
Anyone have any ideas for me to try?
THANKS!!!
