Non start 1.9D

[modmytop]

    Hi all. Just joined and am desperate for help. I inherited a low mileage 70k miles, 306 1.9D, May 1997. It has been starting and going lovely until the other night when I used it for a short trip. Came back to it about 3 hours later and while it turned over, it didn't fire. In fact it didn't even splutter. I couldn't see any smoke from exhaust.
I believe it is a Bosch pump. It doesn't say so anywhere but it seems to resemble other pictures/videos I've seen. I'll upload a pic when I work out how.
Though it sounds like lack of fuel, I checked voltage on glow plug busbar. All OK. Changed 3 glow plugs last winter so they should be OK. Measured 12V at stop solenoid. But no fuel from injector pipe when one cracked open. Also checked timing belt OK, by looking through cover at pump pulley. It was turning when cranked.
Took stop solenoid out. Surprised to see the shaft didn't have a spring. It didn't operate when I stuck 12V across it. So I cut off plunger and refitted. Still no joy!!!! Charged battery over night in case it was low. Tried this morning same thing.
This pump has some wires to rear. Are these to advance the timing? 
What else can I try?
Cheers Bri
