Could be connection at Battery. Remove and clean both terminals. Check connections at starter motor. Remove and clean all terminals on starter motor.

Starter could be locked/entangled with flywheel. Remote chance. If standard shift put in top gear, give car a push with clutch out and see if engine turns over. If locked starter this will normally free it up. Pushing car backward is recommended.
Could engine be hydro locked. Unlikely but just throwing stuff against the wall.
Have you tried jumping car at point where battery cable and ignition switch wiring come together(relay)next to battery,,,,meaning bypass ignition switch to turn over.
Are battery cables clean and tight at each end?
If this all fails would suspect selonoid or starter itself.

Thanks for the comments/ideas. I thought that too about the engine and sadly don't have a socket big enough to fit the crank pulley bolt and it's an auto so can't put in gear to move it that way. I can move the pulley a very small amount by hand holding onto the pulley itself, which suggest the engine is OK. As mentioned it was running a couple of months ago no probs and the engine oil is clear and relatively new. I might try the bypass idea you mentioned to take the starter relay out of the mix but the fact that it's clicking suggests the relay is doing what it should. I might take the one of the batteries out of my truck as well and try that on there, I know they are good batteries on that

You might take off the 2 cables off of the starter & clean the 2 (large/small) terminals with a wire brush then clamp a red jumper cable on both of em and the black jumper cable end to the nearby starter ear then connect the other ends of the jumper cables to your truck battery setting on the ground by the Dr front wheel & see if it cranks. this'd keep the "connection" sparks from messing up the starter threaded studs which it would if you made your last connection at the starter. This'll take the batt/starter/eng lockup out of the way.

Almost sounds like a bad battery that shows it has a good charge...If not I think I would pull all of the plugs if it was me and see if it will turn over freely. You never know a float may have stuck and it could be hydraulic locked...
...FAFO...

First step would be a voltmeter on battery. 12.5 volts as it sits. Crank car. If it stays 12V or so, the starter isnt kicking in and dropping it down. Check for 12V on small terminal of starter. If 12V there and 12V on big terminal, starter is issue. If not 12V on small wire, relay or wiring is the issue. If it drops to like 10V or less, starter is getting voltage on both terminals, drawing power and trying to go. Still might be starter, or battery may just be weak.

I would not put WD40 on your cleaned cable terminals. Holler with any news

Just did the first bit of this, battery off the charger holds just over 13v, then drops to 12.5 when I crank the first time. This then creeps back up on its own to around 12.6-12.7v, when I crank it drops to about 12.5, which suggests the starter isn't drawing power from it enough to crank it over?

Went thru the same kind of issue. The very last thing that I checked was the end of the neg battery cable that connect's to the intake or block. Mine looked ok but I turned the end so that the little teeth ground into the intake and it cranked like never before and this was after restoring the car.

OK, managed to get out and do a few more tests.
Battery seems fine as mentioned, so lets assume for now this is OK, holds charge well and recovers quickly once I've tried to crank the engine, which suggests its ok.
Checked power to terminals on the starter
Small terminal 0 volts when nothing is happening and around 11.5v when I turn the ignition key, so relay must be working OK.
Large terminal reads the same as the battery, about 12.5v and then drops slightly when I turn the key, down to say 12.2(ish)
The clicking is deffo the starter jumping out, I can see this from under the car with the dust plate off the bottom of the bell housing. I turned the engine over manually using the flywheel, so its not locked.
What I did notice though is the starter pops out (clicks) but doesn't engage the flywheel teeth, it pops out and then goes straight back in, which would suggest the solenoid is OK as well otherwise it wouldn't jump out at all, right?
I'll check connections etc now as well but these were all fine last time I started it and its not moved since, so can't imagine why they would be bad all of a sudden?
Any ideas?

Just been out and cleaned the end of the terminal where it joins to the engine block, all lovely bare metal now on all joining faces and still it just clicks Looking more and more likely I'll need to take out the starter I think, which is a pig because of the header being in the way...
