Ok, so here goes my story (i'll try to keep it short)
Last year in the cold I noticed my trusty HDi wouldn't start quite as fast as it does in the summer. No concern there, I know batteries lose some of their capacitance when it's cold.
This year, however, things started to get worse. The last couple of days it took about 8-10 seconds of starting to get the engine running.
Strange thing is, last Friday it started up just fine, even though it was a lot colder than Thursday.
So today I did some fault-finding. Tested the battery: it measures about 9.8 volts during starting and comes back up to 12 when I let go of the key. Not ideal, but not that bad either.
Tested all glow plugs (pain in the **** to remove btw) and found the one on cylinder 2 faulty, so I replaced it.
Used PP2000 to check for any faults, none came up.
My HDi has the "ticking injector" problem, so I listened to all injectors with a stethoscope and found the No. 2 injector making a lot of noise compared to the others.
Made a screen-cap video of me driving around for a bit while monitoring injector corrections: https://youtu.be/jNYK0n-xzg8 (PP2000 is in Dutch, sorry about that) and I don't really see any inexplicable values.
So fast-forward 3 hours, I try to start the engine to go to the supermarket. After about 10 seconds of cranking, still nothing. Turn off the ignotion and immediatly try to start again and it fires right up after about 2-3 cranks. Can't remember if I heard the lift pump though.
So, what could this be?
I'm considering bad battery causing the ECU to miss some fuel pressure values or maybe a bad lift pump or connection to it. The car runs and drives fine though.
Any advice on the situation is very much appreciated.
