heres the deal. After driving around on a hot day i shut my car off and then it wouldnt start again. It cranks well. All the dash lights stay on in all the ignition switch positions. I can hear slight ticks from the fuel pump(not sure how loud it should be but it makes noise) I changed the main relay to a new one. the car started once and then woudln,t start again. I can hear the relay clicking when i turn the key. I how ever have no fuel pressure.(fuel pressure gauge- only thing previous owner did right). anyone have any other ideas?

 

o and there are no error codes on Ecu

 

Pull the back seat and check for voltage reaching the fuel pump wires there. If you have voltage but pump won't run, pump would be bad. Also the pump is grounded behind the seat, check that wire.
