Ok so here is the back story. '98 Jetta Tdi with 378k. Leaking IP head seal and takes 15 seconds of cranking to start after sitting overnight. Cranks instantly when doing a restart and runs perfect after that. Good power and throttle response. Replaced head pump seal with Dieselgeek kit. Previously a few years ago already did the QA and top plate seal.
Cranking time did NOT change but cured the leak after the reseal. Next 500 miles and one month nothing changed. Then over the last week crank times after sitting are getting longer and longer like 60-180 seconds. Now sitting around 8 hours takes several minutes to crank for start. A few days later no amount of cranking will produce a start. Pulled all glow plugs and checked they are working. Installed new fuel filter as it was time anyway. Cracked injection lines to verify fuel to injectors. Verified the fuel stop solenoid working and not sticking.
No leaks of any fuel in any part of the fuel system. No computer codes.
I am stumped....any thoughts on this?
