here we go again ... intermittent starting problem

[goodoldboy]

yesterday setting off from home i stopped at the end of our drive, going uphill, to change out of low box & as i drove on the engine stopped dead - no warning no hesitation or stuttering, just stopped.Pressed for time i abandoned ship & got off ,returning about 3 hours later.Before trying to restart i pumped the fuel filter bleeder & put 10 L of fresh diesel in the tank & she started first time.Now a couple of months ago i suffered the same thing but about 5 KM from home - going uphill cut out instantly - an assumed it was waxing diesel as we had experienced -6 to -8 for about a week & the truck had been standing.
Sunday i had been out on local tracks for a few hours, including some very steep climbs & descents & it never missed a beat.
KZJ 95 starting problems are well covered on this site , the obvious being the fuel pick up inside the tank & as yesterdays probs coincided with a fall in temps. it would seem to be a fuel problem .but my experience with fuel starvation on other cars have always included hesitation/poor pick up etc so im thinking maybe the stop solenoid?

It does sound like the Injection Pump solenoid is messing up. Over time, especially those who run poor quality diesel, rubbish gets through and accumulates inside the actual solenoid and I assume that is what damages it/makes it faulty. I can't think of any other problem it could be, from what you've described and already done.

Just thought I'd let you know I have a spare Injection pump, Complete, if you're interested pop me a PM

Water in the fuel tank .

There is a water trap in the fuel filter, so I doubt it. There is a light on the dash to tell you when it's full

the problem seems to be temperature related - last night the mercury only dropped to 2 deg & today it started first time . no pumping on the fuel filter bleeder.My local & v.knowledgeable mechanic has suggested fitting a non return valve - a cheap & quick "experiment" so ill give this a go & see what happens.
