I am not stupid but sure feel that way right now.
I have a old but in very good condition, 1450 hours, barn kept, a L245DT, that out of the blue decided to give me grief. Apparently the problem is fuel delivery and I worried it might be the injector pump. Now I am less sure.
The issue is the engine starts easily but dies. I checked the tank first. Super clean and nearly full. Changed the fuel filter, flushed the main fuel line to the injector pump. Gravity feed to this connection and fuel flows freely to the injector pump. Cracked the lines going to the injectors and cranked the engine over watching for clean fuel to squirt out each connection. To me it looks good with steady pulses of raw fuel coming out around the connections. All three about the same. Now that I am fighting this I have cracked open and closed each connection probably 25 times. Concerned that perhaps I am letting air back into the injector lines I tighten each connection while cranking. Like I said at first, the engine will start easily and then die. If I start with the throttle at a fast idle position it will start almost normally but slowly starts running rough and then dies. If I start with a high throttle position it starts and sounds good for about 20 seconds before dying.
At this point am I correct to say this is a fuel delivery problem?
