Added more gas still wouldn t start got it towed home and turned the key and noticed the fuel pump wasn t cycling on, ended up replacing it with a new one still it didn t cycle on either. Took the new fuel pump out and plugged the old fuel pump back up just to see if it would cycle on and it did . Would this be a bad wire or something and if so would anyone know where I could find a wiring diagram to fix this issue?
