Yes... there are a few threads on this topic but my frustration is, after lengthy reads I don't really seem to find a definitive solution or path to diagnose.
Maybe someone can answer a few questions to help me out? (BEW, 2005, 450,000kms Running well, no issues starting cold, or even in warm weather first start, but when the engine is up to temp... long cranks followed by a good start, well into my 4th timing belt, tried the Moly purge, fuel and air filters kept)
I do have a VCSD, I scan and I don't have any codes.
-Lift pump... I did a lift pump way back in the km's but I can hear it working, besides if the lift pump was failing would the engine even run? Is there a pressure test that can be performed?
-starter... like I said, good cold starts, Battery is a couple years old, have not checked the RPM cranking but I can't believe it has anything to do with how the engine starts, seems no difference between cold and hot.
-I've checked the timing, seems to be spot on by what I have read... or at least not out of whack and consistent.
-There is no "tune" and the dealer has not touched this car since the glow plug adventure (to steel) a long ways back. Started to notice the issue last year, getting progressively worse. I can't believe (perhaps naive) that the ECU programming could have anything to do with it other then a device not providing the right information.
-Maybe something is up with a sensor but as a bit of a rookie with the VCSD, maybe a little direction on what to look for might be helpful? I would think if there was a fault with the Cam/Crank/Fuel Temp or MAF something would set a code? Or should I drill down in the diagnostics to look for something specific? I don't have any experience with "logging" data from the ECU but willing to give it a try.
Maybe I've missed the "Golden Posting" that has the answer but I did do a fare bit of reading before posting this. Few if any had a Eureka moment, save for one that changed the cam sensor and had a solution. Not a big fan of tossing parts at something unless I have evidence.
Thanks for any help,
Martin
