Thanks for your suggestion. Yes, I know it happens sometimes but this boat has no kill switch... Perhaps it is one of the sensors, of throttle position or crancshaft, I don't know. Tomorrow I'll have more time to look into the problem again.
Unfortunately, still no luck... I've installed new high pressure fuel pump (it works), 2 new injectors (work), 2 new relays, checked all the fuses, the starter cranks, spark is present, fresh fuel. But engine doesn't want to start anyway, nothing. Should I call an exorcist?
Thank you all of you guys. Once the pump is available I'll try to test the original configuration of the switch once again. The problem to me is that in the first slot of the fuel pump switch power is always on, no matter the ignition key is on or off. But perhaps it is as it should be and MEFI...
Thank you for your help. I'll try to get the manual. I can't check out the fuel pumps with the ignition key now because the high pressure pump apparently have died so I dismounted it yesterday. It doesn't show any sign of life after connection of 12v to the socket, only one click. I'll get the...
The problem was there was no ground in the fuel pump relay socket and there was power there no matter ignition was on or off. Today I
connected both grounds from both switches together (black cable) and
both powers from both switches together red/purple. I disconnected two cables from the fuel...
Thanks for your suggestion. It's raining here now so I can't check out the engine type again. I'm not a specialist, I bought this boat last year thinking it was a GXi but strange things happen, it could have been a kind of conspiracy like the fake C-19 pandemic or the monkeypox unfolding now...
Hi, there is no ground in the fuel pump relay socket of my Volvo Penta 4.3 GXI engine so it cranks but doesn't start. There is spark but no fuel. If I connect the ground slot of the relay socket to the ground on the engine then the fuel pump starts working. But normally after switching on the...
