Okay guys, Finally got everything together and Went to start the car, nothing. Dash lights are on, fuel pump isn't priming, there's only one click coming from the fuse box each time I try to start it. Checked all my grounds. I have 3 grounds on the motor, and It still won't start. Tried jumping the starter and it would turn the car over, but fuel pump still isn't kicking on. Had somebody come over to try and fix it somehow he jumped the starter and killed the power inside the car, now Nothing is working on the interior. Used a multimeter and everything in the engine bay is getting power, fuse box, fuses, etc. Fuse box inside the car isn't getting any power at all, and neither is the main relay. Any idea on what this issue could be?
