poor starting 90 - getting there
Matt_H:
we seem to be getting a bit better at starting the 90 in cold weather or after a day of not running, so far
battery replaced - turned over much quicker and doesn't die after tryign to start on x'th attempt
timing belt replaced - runs smoother as timing was out a bit
fuel lift pump replaced - once running no longer takes 30 seconds before throttle does anything at all.
Now when really cold, like minus 2 like it has been for the last few days first thing in the morning it takes between 2-5 goes to start, it turns and fires maybe a few revolutions then it dies. Same again, when I first repalced the lift it was normally the second time, but now its 4th or 5th however the weather is much colder. Should I be suspecting the glow plugs (which I normally fire up for 20 seconds or so (tdi converted from td so on manual key switch).
One other thing worth mentioning is that when the car is warm and switched off I can pump the handle a couple of times - it then goes floppy which I'm told is the normal pumped up symptoms, leave it 10 seconds and I can do at least one handle pump before it goes floppy again - also on release you can hear a faint sort of squeak like the pressure reducing in the system.
I've tried pumping the system before starting (both with fuel solenoid open and closed) neither seems to make a difference, is there anyway air can leak into the system and cause bubbles of air. Once warm she runs perfectly and if I try again at lunch time or early evening again fine no problem... as she is my main form of transoprt I've not been able to try mid day without an early morning run.
This is driving me wild now so your help gratefully appreciated!

Hangover:
Maybe the water loss is connected to the poor starting.

wet with what?

If you are loosing a bit of coolant into one of the pots, this could cause poor starting, not very likely but worth a look when checking other things
