99 E300 TD - cuts out

[TMAllison]

Subject car was bought and shipped from out of state. Upon arrival, drove down off transport truck, idled roughly and then drove 100 yd to my house. Smartly. Was turned off to admire and wouldnt start again. Check engine light on. Wants to run.

Towed to Indie I've used for other diesels 4 days later. He's very good with older diesels like my 85 300TD; perhaps not curent enough equipment for the newer ones?

5 hours mechanical/electrical diaognostics later after cpmputer disclosed no error codes he put dip stick in tank to confirm indeed had fuel and smelled gasoline. I've seen, smelled and am inclined to agree.

Completely drained fuel system and replaced filter. No help. Prior dianogostics showed 2 bad glow plugs, 2 low and 2 good resistance. Replaced all. Started for first time. Check engin light still on. No code.

Idled ok. Rev'd OK. When driven cuts out under full throttle. Air in fuel lines.

Replaced pre-filter and o-ring. Helped; is now possible to start and drive, but continues to cut out w/o warning. Instantly! All speeds, idle to full throttle.

Whenever turned off, fuel line from Fuel Thermo to Pre-Filter drains. Line has new o rings. Typically when cuts out exhibits whoose of air from pre-filter back towards thermo (line 606.070.1432). This is backwards right? This is the fuel feed line.

Is very little air present in lines now. One or two itty bitty lil bubbles every five minutes. Blink and you miss them.


Still cuts out at idle and while crusing (at idle seems to be when temp hits 86 or 87 C, while crusing dont know...am usually busy looking for someplace to pull over).

Priming pump 40 secs to start does nothing other than drain battery. Coughs, splutters, wont start.

To get started again, have learned to
1) turn ignition off
2) disconnect electrical connection to fuel shut off
3) turn ignition on
4) reconnect electric connection to shut off
5) turn key past position 2 and start

Question....what do I look at next to resolve the cutting out. O-rings at all fuel lines? Fuel thermostat? Fuel cut off valve? Other?

And most importantly why?

Thanks
