I've finally come to restart the 1850 after all the gearbox and body work.
Here's the mystery:
I have spark (although the frequency of the spark seems "odd") - checked with a plug resting on the engine top connected to #1 plug lead. So maybe just a poor/intermittent earth as I'm cranking?
I have fuel to the pump (removed feed pipe - fuel visible in the end of the rigid pipe section)
I have NO FUEL - carbs and pipe work dry as a bone with the pump on the engine.
I have fuel OUT of the pump IF I pump it by hand with the pump off the engine.

All of this was working fine before the engine was removed and I haven't messed with the engine (just removed the gearbox for a strip down)

Engine is turning over at a decent speed and the battery holds charge nicely.

If I didn't have spark I'd have thought it was a jack-shaft problem? But I'm a bit stuck now - how do I have spark but no fuel pumping?!

Thanks Dave I'll check it, weird though as it worked when I pulled the engine and I re-tried it before pulling the pump.
Very odd.

Good shout Dave! I realised (done so many jobs I'd forgot) that I took the pump off when the engine was out to paint the block!
Took 3 or 4 goes to get the pump positioned right and bolted on, but the car is back up and running - thanks!
