Yep, that’s probably your culprit. Real simple to fix man. Just make sure the car is off.Pull the fuse, from the add a fuse to that green fire, make sure you have 2 10 amp fuses in there, plug it into the fuse box and see if that fixes it. Save you a lot of money. If it’s not that connection there’s probably a relay somewhere. If not, then maybe your pump is dead or your stock pump is causing a ton of resistant which i doubt. Did you hear the pump in the trunk running at all?
