I recently -(about 1 mo ago) sent in my ECU for a 2001 Evinrude 250 DFI and it was given a clean bill of health. The engine stopped at idle speed and would not restart.
Items I have replaced below;
- New 70 amp relay
- Quick start relay
- New starter Solenoid
- New High pressure fuel pump
- New OEM Starter
- New 800 cca Optima Battery (old starting battery was found bad with initial problem)
- New fuse panel and all fuses and relays
- New crank shaft sensor
- New air intake sensor
The engine started and ran for about 30 min with consistent restarts after manually activating all the injectors via software. Now it's doing the same thing again...no start. It left me stranded and had to be towed on vacation. NO boat at Hatteras; What a bummer!
Items replaced after running for 30 min.
- New starter switch
- New injector voltage filter
- New capacitor
I have not replaced the charging stator or the throttle position sensor,
Eric at DFI suggested some CPS testing, below are the results
- Cranking with new battery freshly charged... no RPM on test software...even on dual batteries.
- Cranking with # 5 FUSE removed... No RPM
- Cranking with plugs removed... 256 RPM
DFI believes there may be a problem with the harness. Software shows no fault codes or stored codes.
Thanks for any insight or suggestions
