XUD not starting when hot - Compression Test

[Harky]

Right so got home tonight to look at her.

Put in three different injectors, and one of the old ones, got her started up. Let her get up to running temp. Stopped her and started again, turned over for a couple of seconds and started. Tried it a few times, all seemed good. Left her running while I did a few other things, fans came on a couple of times but brought the temperature down nicely. Thought right, this is grand, I'll go for a drive, check all else is ok.

Next thing she goes real knocky sounding and vibration, drive 100yards and it clears itself again. Go for a drive up and down the road (sorry private driveway) going the best. Come back to the house, park up, thought I'll check this one more time, no start. Pulled all the temp sensors, still nothing. Ran a wire direct to the stop solenoid, still nothing. Pumped the grenade up hard and it was going soft under cranking.

Also checked timing, cam lined up perfect, bottom bolt on pump lined up perfect, top one lined up but wasn't just square enough to screw in easily, not enough to be a tooth out though imo.

So, yeap, well and truly lost now
