Hello, I have not been here for a while since my last boat. Been working on some issue with my motor for the last 3 weeks and can't seem to figure things out. Doing tons of reading on different issues with "won't starts and what not"..
I have a 2001 volvo penta 5.7L that wont' stay running. Ran fine last season no issues.
Took it to the lake no go! Engine stalls and won't run more than a few seconds. advanced throttle still dies no change.
changed:
plugs
cap/rotor were corroded- thought this was the fix!
new wires- triple checked firing order
fuel/ water sep. filter
tried seafoam blackened my new plugs - old plugs back on
oil pressure sensor tested -249 ohm
oil pressure switch rusted- cleaned rust and connector a bit
iac cleaned - seems to be working
bought cheap iac for testing both working identically
fuel pump has no visible paint chips coming loose- runs with the 2 beeps and after the engine stalls
had old fuel from last season that has never been a problem on first season start. Added 12 more gallons last month.
batteries take a full charge
I also see the oil pressure at zero when key is on, 40 psi when engine cranks, disconnected the blue wire to ground it pegs to 80 psi with key on. Is this normal?
I'm not sure what else to do next. Talked to a mechanic from a marina and he said it's my stale gas use seafoam. He swears it should fire up.
any help much appreciated.
