Fried ecu???
So recently done a engine swap and i took it out for its first drive, was going great till one of my intercooler pipes came off which caused the car to bog down and stop. i got out the car reconnected it.
Now here's the important part on my main relay to get my fuel pump to run i have to have a wiring joining 2 of the pins together which i unplug and re connect every time i start the car (p.s this was a temporary thing was just testing car) now when i get back in the car the wire popped out of 1 pin and hit a ground causing it to spark. After this my car simply would not start and would not prime the fuel. I checked i hadn't blown my fuel pump so i primed it manually by tapping it into a 12v source which made it prime so i knew i hadn't blown that, the next thing is i checked EVERY fuse in the car and found they where all good. Upon running some tests it seems i am no longer receiving power from the ecu itself. I have got a 2nd identical ecu on its way to me will this fix the problem or will it just be the wires leading to the main relay?
p.s the car is a 99 sport with a 94 jdm turbo in it.
Let me know.

Checked the fuse and sadly it is still in tact, also if i may add the engine still cranks but nothing else all the dials still work ect just doesnt actually start and when i unplug the ecu and try to start it it does exactly the same.

Just checking, but are you aware that all of the transparent topped 'cubes' in the engine bay fuse-box are in fact fuses, and not relays? Have you tested all of them to make sure they've got continuity? All of the 'SBF' fuses that you've got in the diagram below. They seem to be the most likely culprits:

Glad you found it.
They're known as J-Type PAL fuses. EuroCarParts do supply PAL fuses, although they don't say whether they're mini or maxi size:

Alternatively, eBay (as usual) has both sizes available:
