I recently got my car back from the paint shop. I started the car and pulled out of my garage and then turned it off so i could do some work. I started it back up instead to let her warm up and it wouldnt start. The car would crank over but i noticed my fuel pressure gauge is reading zero. We let it sit for a couple minutes and noticed my fuel pressure when back to 20, normally its at 40. As i try to start the car i watch the pressure slowly drop to zero. I tried to listen for the fuel pump when i turned the key on and no noise... so maybe thats the bust, but could it be the main relay?? how do i check if my relay is shot. I tested the connection to my fuel pump and it was only get 6.4v... I need to fix this before monday because the car has to drive cross state for a big inspection and if i cant make it it will take a month to get another appt and get it back on the road. Please help.
