Beams is in - but won't start Options

[S8S8]

I've just finished converting my Aussie ST204 to Beams power using an ST202 SS-II clip, but I can't get the engine to start.

The engine turns over, but won't fire. We're pretty sure the problem is the fuel pump, as there is no fuel pressure. The relay on the ECU is operating, so the issue seems to be somewhere between there and the fuel pump. It was working fine with my old 5SFE just last week, so I'm sure it must be a wiring issue rather than an issue with the pump itself.

There are issues with wiring to the new instrument cluster too. It's way off, with all to wrong lights coming on for the indicators and high beam etc. The dash lights don't work at all either.

I'm not so worried about the dash issue at this stage, but thought I'd mention it on the off chance it could be connected with the non-starting issue.

Any assistance would be greatly appreciated.

I know you guys are far more experienced than me, but here's what I don't understand: If I have replaced everything from the donor car into my car, and the engine started fine in the donor car, why would I have to repin or rewire anything? Obviously if I was using my original interior loom or whatever, but literally everything has been replaced.

Here's what's been changed so far:

Engine & gearbox
ECU
Engine wiring loom
Front chassis loom
Both interior looms
All dash parts including climate control & cluster etc.
All fuse boxes, relays and whatever else was attached to the car

Basically the donor car is completely striped bare and everything is now installed in my car. The only things that haven't been changed are the bodies.

So with that being the case, why would anything need to be rewired or repinned?

But anyway, I have more bad news to report! I finished swapping over the front chassis loom today (what a job!) and now I don't get any ignition lights. I've checked all plugs and fuses etc, but can't find any issues.

I'll take a pic of the pedal box from the donor car tomorrow, but I can assure you there is no switch on there like with my car. Is there anywhere else this clutch switch could be located on an ST202?

Thanks, I really appreciate your time.
