Default supra 2.0 twin turbo non starter

My mate has just got his hands on a wide body black GA70 with a sunroof

It won't start up at all fuel pump runs on engine cranking and using diag block it just keeps cranking and cranking

There is 1 fault code and its 34 checked all that area and all is sound

plugs getting fuel and sparking the car will start with brake cleaner up the intake but cuts out one dry any help would be very greatfull

If the code 34 is persistent you've got a wiring problem or the sensor or ECU has a physical defect. If it were just a boost leak you wouldn't see it until the engine had been run.

Have you made sure you've got spark when cranking?

Check for a signal on the STA input at the ECU while cranking.

I can't offer much in the way of specific information, the 1G never made it to the 'States' in any form and I don't know of any online resources for the 1G. This forum is largely US-centric (not by design), there is a UK specific Supra forum (mkiiisupra.net) where I'm sure you'll find more 1G-GTE owners and resources.
