Thanks: I did not do the obvious, and it has caused me a lot of headaches. This morning I tried to start after yesterdays sucess, and once again a very hard start, but it started, wheras before the fuel line problem was solved it would not start at all.

So I checked the glow plugs and yes 4 of the five where DEAD. so I replaced them, now the funny thing is I put in two new ones less than a year ago and they were also dead. So anyone reading this. "CHECK YOUR GLOWPLUGS, I don't care if you think they are fine, CHECK THEM NOW!!!!!! not tomorrow,not think about it, NOW!!! NOW!!! NOW!!!

This is an easy way:

1. with a voltmeter and the GP's connected, turn on ignition, measure the voltage between a good ground connection and the lead going to the glow plug, check ALL of them for voltage, if the voltage is present (12V) all is good so far. it shows you are getting power to the GP.

2. Disconnect the wire from the 1st glow plug. (With the ignition off.) put your volatge meter to OHMS setting, or better still if you have one the checks diodes with a beep sound, use that setting. Place one lead of the meter to a good ground, and the other to the connector (on the glow plug), and check for continuity, it will beep or it will show continuity in the OHMS setting. If the cuicuit is OPEN, (ie no Continuity) the glow plug is bad. do this for ALL, and I MEAN ALL glowplugs. I am sure that this is 90% of all hard start, cold weather problems. Hope this helps for anyone having hard, cold, starts. CHECK YOUR GLOWPLUGS, NOW!!!!! Do NOT take for granted that its too obvious, CHECK THEM NOW, Also I would stick with BOSCH!!!!!!!
