fixing to blow up a boat!

I agree with smokin' gun
try swapping the dist or the module. You could also rig up a meter to the wires on the VST pump, or just jumper it directly to the battery to test. Just need to start isolating and figuring out what isn't working. If you think the problem is with the ECM, try swapping that also. Hope you get it figured out!

Hook a timing light up to any of the plug wires...1 is ok .....See if when the motor dies the light goes out ....that will tell you definatly whether it is fire or not ....You could also have a fuel pressure gauge attached on same test and watch results ...it's ez
Obviously check for water in fuel

thank you to everyone! I think i have fixed the problem. the boat has 2 water/fuel separators on each motor....why? i have no idea.
I bypassed the Racor water/fuel separator and connected directly to the one on the motor and it ran fine. I just think that trying to run
a 4-7 psi fuel pump through 2 water/fuel separators might just be a little to much.

She likes to play around in the cuddy usually while i am tinkering. My 8 yr old boy would rather stay inside playing, but not her.. dirt is her middle name. Usually, she just take my tools and plays with them then i am like wtf, where did it go!! Lol

Thinking they are like 6.2s. When you key on the pumps go on for 10-15 seconds then shut off if the do not detect oil pressue. There is a switch on the right side rear of a 6.2, its not the sending unit just tells the ECM there is oil pressure. That might be bad if your engines have it. A quick fuel pressure test will tell if they are in fact shutting off.
