I’m looking for some advice on my quest to get to the bottom of my cold starting issues.
Symptoms:
Under 7degs C - car will start then immediately stop after about 3 seconds
Repeat about 10 times, will eventually keep running
Over 7degs C - car will start 2nd time and keep running, 1st time it nearly starts
After reading fault codes I’ve changed:
Air Inlet Temp sensor - sensor head missing, car now runs better but fault remains
Glow Plug on cyl 4 - was open circuit, car starts a little better
Glow Plug Relay - no change after this
Yesterday I tested the fuel filter pre-heater - open circuit
How critical is this? Does this only come into play in extreme cold?
I’m noticing air bubbles in the fuel line after the filter, no leaks apparent on filter housing. Could this effect cold starting? Doesn’t effect running once started
I’m thinking of buying a proper Vida/dice setup but I’m unsure if I will find out anything more from it
Any help appreciated,
Craig

Vida is a good idea.
What about fuel pressure? How about cycling the ignition on and off a few times to position 2, ie not starting it but ignition lights on to force the fuel pump to prime each time then see if there is marked improvement? If it does, at least it would give you a direction to look into ,whether that be the pump, injectors, fuel filter assembly ... Even so Vida is your friend.
