2003 Volvo Penta 5.7L Gi-A...long block replaced in 2017.........was running great...up on plane......slowly started losing RPMs (over 4 minutes) went from 3,400 rpm down to 700 rpm then died.....will not restart. Tested all ignition components....tested good....replaced anyway. 12.6v feeding coil. Retested all ignition components...all test showed good. Timing marks spot on with #1 at TDC. Cap and Rotor replaced, ICM replaced, Ignition Pick-up Coil replaced, Ignition Coil replaced, TBI Injectors working, New Fuel Pump working fine, Fuel Filters replaced, Wires replaced, ground wires cleaned and secured.....VERY WEAK to no spark from coil post .....only thing hasn't been changed out is the ECM........still no start.
I am lost and have no other ideas what to try. I have a full set of Volvo Penta Workshop Manuals given to me by a former Volvo mechanic....I still can't figure it out......
My boat is on my lift in my canal so I can't get it to a shop for a full ECM scan and can't find anyone who does house calls.....
I did a DTC and got a code #44....but I think that was from disconnecting the knock sensor during my trouble shootinig.....
Any help would be appreciated
