no power to fuel pump

Im only getting 2.7 volts to my fuel pump and 7 to my guage. Relay is good. Omhed wire and it seems to be good. Could it be a bad computer. I ordered one on a hunch.

Ground is good to. Thats why im hoping computer works. I spent all last weekend tracing wires and grounds, they all checked out. I did have it in deep water not to long ago. So maybe it got in computer;;

Shutdown relay? It runs in conjunction with the fuel pump relay.

I had a bad computer same thing but fuel pump only comes on for two or three sec if not running so it's hard to check for power unplug crank sensor then turn key on and see if you hear the fuel pump come on if so it's the crank sensor
