I set up a pipe running from the TB to the turbo outlet to see if it would run and it did. I let the engine warm up and took the fuel pump fuse and all the spark plugs out to do a compression test that came out great. I put the fuse and plugs back in and didnt touch it for 2 days. I just tried to start it again the same way and now the fuel pump will not come on. Hopefully, that is the only problem. Any ideas, the fuse isnt blown and I tried other ecus that also wouldnt run the pump.

It's not coming on at all, not running the car? Or you're not hearing it come on?

I'm guessing it's with the fuel pump itself then. Release the fuel pressure and double check the wires for the fuel pump in the tank. Maybe they're loose or are disconnected. It could also be the main harness.

I doubt it's anything major. Double check the wiring(s) and let us know how it turns out.

Weird, I just simply opened the fuel pump cover to make it easier to hear it and swapped the fuel pump fuse which wasnt blown with the one for the horn and it started up fine. Thanks for the help.
