Alright guys I got my car all back together and I went to start it and nothing happened. Mpi fuse keeps popping. I've checked a few things and a couple different threads but the information leads no where. Any tip or info would be great.

Did you replace the fuel pump while the car was down by chance? I did this on a 90 GSX several years ago and accidentally pinched one of the wires while putting the metal cover back on and it kept shorting and popping that fuse every time I hit the key. Just a thought.

Thanks for the link I'll follow this. Got it narrowed down to the mpi circuit off the ecu but I keep finding broken wires and more bs than I wanted.

No I didn't replace the fuel pump in this build not yet anyways. I plan on selling it once it starts and runs

It was self inflicted. A stock boost solenoid wiring was under the battery when I tightened it down and shorted to the battery tray causing it to pop.

Same thing happened to me except the solenoid fell down to the axle. It would allow me to start the car and try to drive it and then when the axle turned and knocked the solenoid to just the right spot it would short. PITA to find. We were troubleshooting it in the dark and saw the spark was how we noticed it.

Yea we took the harness all out of the loom and everything and just so happened to see the connector under the battery sticking out.
