I did a lot of searching, and that was my downfall. There's so much information out there, and lots of it was conflicting. So, I'm just going to type my specifics here in the hopes that someone can help me out.
99 Golf, TDI, 250K miles
Friday I'm driving to work and after about 11 miles it starts to stumble. This happened on the highway, after about 9 miles of country road driving and 2 miles of highway driving. I pulled onto the shoulder and it seemed to idle fine. So, I puttered on the shoulder for maybe another 100 yards before it just died. Here's some info that might come in handy.
I've only owned this car since the spring and this is my first winter with it.
I don't use any fuel additives (like diesel 911 or other anti-gell additives)
Never had bio diesel in it.
The temp was 12 below zero at the time.
I had about 1/4 tank of diesel.
It has a long crank issue, has since I've owned it.
I had it towed home and later that afternoon, when the temps warmed to a balmy 8 degrees it started. I then drove it to the gas station 2 miles away, added some anti-gell, filled the tank, and drove back home. Today, temp was about 25 degrees and I took it for a longer drive. I only made it 1 mile to the highway, then 3 or 4 miles on the highway before it started to buck and stumble again. I pulled off and drove surface streets home and all was well. I decided to replace the fuel filter since I have no idea how old it is. I replaced it and primed it and it did start after lots of cranking, but wouldn't restart a short time later.
Fast forward to today. So I went out to the garage and primed the filter again. It only took a few ounces. It started up after a LOT of cranking and ran fine. I let it idle for an hour while I dug out from snowmageddon. It idled and revved fine. I shut it down and restarted immediately. It took maybe 5 seconds of cranking to start. I shut it down and restarted again, it took a bit longer to start this time. I'm suspecting the tandem pump but don't have a way of checking pressures.
I'll add this. After the initial failure, when I got it started the next day and pulled it out of the garage there was about an 8" puddle of oil on the floor. this car does seep oil, but does not spot on the driveway. I suspect the tandem pump leaked fuel down the engine, washing oil from the engine and skid plate? I cleaned the area under the pump and it looked dry after the hour of idling.
Any input before I drop a few hundred on the pump?
Sorry it was so long and blathering, but any help would be greatly appreciated.
