2003 volvo penta 5.7 GXi quit running from idle after engine heated up slightly [from kelp] and whining fuel pump. Would turn over but not start. I pulled a spark plug and grounded it to a bolt on the block. My son turned the motor over and I saw spark. It even gave me a good jolt when I slipped and must have completed the circuit accidentally. I could hear the fuel pump priming , but when I pulled the line from the tank to the fuel pump it was bone dry.
I figured given the age of the pump, the whine and other findings it was probably the pump. I replaced it and the fuel filter. I filled the filter with gas before replacing it. Now I get a "beep" when I turn the key on [so I am guessing its not the kill switch stuck?], and hear the electric pump priming. But still not starting. I put gas in the tank just in case it was out and the gauge may have been broken. When I pull the fuel line from the tank to the pump and place it low in the bilge, gas does drain so I don't think its clogged. I can only find 1 50 amp fuse which is OK. I replaced the fuse to the fuel pumps [F7 on my boat].
The boat still won't start and the line from the tank to the pump is still bone dry when I pull it and check it. My first thought is defective fuel pump, but it was a new Volvo part, from an online retailer. Any thoughts? Thanks.
