Our Detroit Diesel 671 two stroke engines will not fire. We've had the boat for 4 years and the engines have been run and seemed to be working fine. Then both engines stopped within 10 minutes of each other. Here's the history:
After installing new Walker fuelseps, port engine started, stbd engine cranks but wouldn't fire. Within 10 minutes the port engine would not go above idle and then died. Both now crank but won't fire.
Had fuel tested, came back 310 out of 1000, a good report.
We understood there's probably air in the system. Replaced fuel hoses. Took racors completely apart, cleaned them, installed new filters in them (even though they looked clean). Engines crank but won't fire.
Installed an inline fuel pump, bled the fuel injectors one at a time. Engines crank but won't fire.
Checked fuel pressure, it's running about 5 to 6 pounds.
Any suggestions on what to do next?
