Please bare with me, I'm new at this
My 110 wont start ('88 110 LHD 2.5TD). It was running fine on Friday, I drove it to work, 30 minute commute x 2, a few other short runs. (I use the Webasto to warm it up). Then I parked it in the garage.
Saturday morning, loaded the truck with gear and family for a fun day at the park...
Webasto warmed up the engine, and when I turned the key, one puff of smoke and 1 second of running followed by a stall.
Then the engine just cranks. Doesn't catch at all. No smoke.
No warning lights.
I thought I found the problem with a frayed wire to the fuel solenoid, but there's 12 volts at the solenoid, so that apparently isn't the problem. I did have a new webasto fuel pump installed last week, so I thought maybe there was air in the system, so I bled the filter and the injection pump.
Nothing has changed.
I'm thinking this is a fuel delivery issue?
I have a full tank (filled Friday afternoon)
Could a fuel pump just up and die all of a sudden?
My thoughts are: I have to check the fuel pressure. Fuel backflow? Air leak somewhere?
I don't think glow plugs are an issue since the outside temperature is now warm? Or could that still be an issue?
I would appreciate any other thoughts?
