I have a Volvo Penta 5.0 GXi-A. 4012050969 3869116
We had to remove the engine from the boat to do some water jacket repair. (Yep, I welded up a cracked water jacket.) When I re-installed the engine, It turns over, have ignition, compression, and timing. IF i pour a bit of fuel down the throttle body it fires right up. Unfortunately, it is getting no fuel from the fuel pump to the throttle body.
I have taken the fuel pumps off and applied 12volt to both the high pressure and low pressure pumps. Both pump diesel just fine. Fuel filter and pumps were purged with gasoline and re-installed. Both relays have been tested good but replaced anyway.
I have NOT been able to locate a fuse blown. The schematic shows 4 fuses. One is for the fuel pump. I have only located 3 fuses. All three were in he box on the side of the engine that has the diagnostic port. All appear to be good and were tested with a VOM. Is there any other place to look?
I use a paper clip and test light to see if there were any codes set. None showed up.
What is my next step in finding out why I have no voltage to my fuel pumps?
Thanks for any assistance and advise!
