    2003 5.7 gxi Volvo penta seems to go into safe mode with no alarm

    Ok here was the answer “fuel pump” changed the entire unit. I guess one clue was the plugs showing lean condition. The tricky part of diagnosing was the fuel just seeming to shutoff at injectors. Made us think ecu for a while also fuel pressure held at 30 psi. But thinking back to lean looking...

    2003 5.7 gxi Volvo penta seems to go into safe mode with no alarm

    Thank you again, scanners not cheap in Canada, we have a way to go to get it hooked up for scan. We at the end of season, will recommend trailer to the marina about $120 to get that done. Just funny that the pump started to whine after our get onto plane run. But if throttle back it will not...

    Oh yes a new pick up was installed same time as anti siphon valve. The stuff they install the anti siphon valve with omg, so it broke off and had to replace the tube also

    Thank you, I should have started at the beginning so forgive me. To date, new anti siphon valve and gas hose, cap rotor, wires. I sat at engine out on the river and when trying to hit plane the injectors flowing and pump at 30 psi, then just seem to run out of gas at injectors. water separator...

Had the HP out and as gas drained may have dislodged and paint, the low pressure pump started to whine but was not hot to touch.while watching tbi injectors once on plane at 3000 rpm the injectors seemed to...

    Update- changed spark plug wires as a matter of maintenance. Disconnected temp and oil pressure switches to ecu. Biat hunted a little at idle then settled down. Took out and was able to get it plane , but not go past 3000 rpm. When you try to push past it just stops giving gas and backfire. The...

    Thank you Kosmofreeze, I looked into the unit you mentioned talked more about dashboard stuff like a comparison, does it read your sensors?. I was at boat today and did find the wire off of oil pressure switch that I believe sends info to ecm. Will take it out later to try.

    2003 5.7 gxi Volvo penta seems to go into safe mode with no alarm

    Wondering why it would seem to go into safe mode without an alarm. One injector stops and boat backfires stalls. Easy to re start, plugs running whiteish so lean, fuel pump at 30 psi steady. Any thoughts please, I am also new , so please bear with me if I am posting wrong. Thank you
