So I was running the boat the other day, ran great. Shut the engine down for a few minutes and when I went to start it back up it would crank but not run. After doing some field testing I found that if I squirt some fuel in the throttle body it would run but only briefly. That made me realize it was a fuel issue. I then noticed the fuel pump was not priming when I turn the ignition to on like it usually does. So at this point all I can figure out is my fuel pump is not getting power.

Here is where I’m lost, I hooked the fuel pump up to my trucks battery and both the HP and LP will run. I also used a meter to see if the connections to the fuel pump were getting power, which they were both getting more than 12v. But when I plug the fuel pump to those same connections I get nothing.

Any ideas? Could it be a sensor not telling the ecm to give power to my pumps? Is it a relay switch? At this point I’m willing to try anything.
