To sum it up, I came back home from tech school the other day and my car ran perfect for 2 days besides failing inspection and being too low and my tint. My dads battery died so while he was charging the battery, he hooked my battery straight to his battery cables with jumper cables to put his windows up and I saw my afr's start leaning out to 15.5. So I hurried up and popped my hood to check if something was loose and my car just slowly died and shut off. I attempted to start it and it turned off but wouldn't start. I then realized my fuel pump was not priming, so I started trouble shooting that. Found out the fuse was blown and thought everything was going to be straight. Went to start the car and the pump still didn't prime. So checked the relay and replaced it for the hell of it to test it and it still did not prime. So I assumed it was the pump, so my wife and I pulled the pump real quick and tested the pump and it's completely fine. So, it obviously means its not getting power? So I'm assuming there's a bad ground? Is there anything else that would cause my fuel pump to not prime?? Would the maf have anything to do with it?? Any help is greatly appreciated. Thanks!
