B230F LH 2.2 no run after cam swap

I've attempted a DIY cam swap in my 240 with a B230F motor. Not starting post assembly, I did pull the timing cover off to double check cam timing lines up...

More of an overview pic holding camera high so we can see which direction the leads are going to spark plug wise. Don’t need plugs just dizzy and most of the leads.

Cant be too careful at this stage of the investigation.

Next step, have an assistant turn motor over just a little, while you have a hand on the fuel pump to feel for a buzz.

I also did a long crank with injectors unplugged, car seemed to fire up for a sec or two.

I happened to be under the bonnet of a 240 just now and also noticed your distributor looks fairly advanced compared to mine.

You have setup your timing belt correctly, but the last person to touch it may have got the aux shaft pulley off by one tooth, then advanced the distributor to compensate. Now you have set it correctly and the distributor is just way too advanced. A timing light would reveal all, but short of that maybe just mark the current position then move it toward the centre of its adjustment range and see if you notice any difference.

Unless the photo is tricking my eye, I think @Anthony is onto something, because the leads do appear to be in the wrong order. It looks like you have them 1-2-4-3, rather than 1-3-4-2.

They need to match up to this:

Well @Anthony and @jamesinc were on the money.

Turns out leads 2 & 3 were the wrong way around. I've corrected that, did the clear flood procedure and it fired right up to a smooth idle.

In my defence, the handwritten 2 and 3 looked very similar Image description

Thanks everyone who contributed knowledge. I'll have to complete reassembly then road test with the vx3 cam.
