500 EFI fuel pump - intermittent problem
 

I have a 500 EFI with a procharger that was just reinstalled in the boat. Motor ran perfect on the dyno and now that it's in I'm having an intermittent issue with the Aeromotive 1000 fuel pump. Sometimes when I turn the key I get full pressure from the pump and others I can barely hear the pump running and it builds no pressure. I've checked the fuses at the rear harness and there's no corrosion there. The pump is almost impossible to reach. Not really sure where to start troubleshooting, any suggestions would be greatly appreciated. Thanks

OK so checked everything and found there was power to the pump. Ended up pulling the motor again and pulled the pump apart and found a broken solder connection inside the pump. Put it all back together and works fine. Just an FYI in case anyone else has similar issues
