1998 Mercruiser 350 MAG MPI EFI
Trying to be absolutely sure before I spend the $350 to replace Fuel pump and cooler (can only purchase the complete unit now)
Out surfing and the boat bogged down and just died. will turn over but not start.
- Spark yes
- Fuel pump makes normal start up noise when ignition is turned to the on position
- Fuel/water separator and filter full of 3/4 H2O and grime - replaced and filled with clean fuel.
- fuses related to EFI good
- Kill switch good
- Main breaker good
If i take a primer bulb in a fresh can of fuel and hook it straight into the fuel/water separator housing I can prime and start the boat and keep it running (albeit rough)... my last hope is that there may be a relay or something??
Anyone have any last ditch ideas for me?
