Okay folks,
My sick little 1999 E300 Turbodiesel is about to drive me mad, but I think I've got it now.
The car has been acting like it has a fuel leak/air incursion/maddening flow problem for the last seven months. The Injection Pump nails a bit, the car will stutter and stall when the temp outside drops, and there are some funky events from time to time. The stalling never occurs at idle, only when at highway speeds. It feels like the car wanders on the road due to the engine missing... frequently. Injection Pump clatters and nails a little at idle, like it's starving for fuel. The only plus side is that my fuel economy is up a bit.
At first, I suspected the "lift pump". All the symptoms were there: poor flow, stuttering, nailing. So I was prepared to repair/replace the lift pump. Then my girlfriend told me something the other night. She had put the key in the ignition and when turned the car did not crank. Not that it would not start, the starter itself refused to turn. The next night the blower regulator fried. The remote lock/unlock is funkier than usual too.
Soooo..... I'm leaning toward the K40 now.
I've vacuum tested all of the fuel connections, and everything is airtight. There are no more air bubbles in the system. So it has to be this or the lift pump.
