Bought a 99 new body style jetta tdi. Has 149000 on the clock.its been starting fine for weeks. Now all of a sudden when it sits for longer than a couple of hours you have to crank the crap out of it to start. When it starts it smokes really bad and clears up. But runs great. When it's good and hot it only turns over a few times and fires right up.no fuel leaks. Haven't done a compression check yet. But no codes nothing. It just started this out of the blue.
