with a fuel pressure gauge is how u check ur fuel pressure. find ur fuel rail. should be a plastic "tire cap" and unscrew it. u'll see what looks like a tire valve/schrader valve and screw ur fuel pressure gauge adapter to it. turn key on KOEO (KEY ON ENGINE OFF) and see what gauge reads. if at first there is no fuel pressure......and gauge reads zero......try starting it. at which time u should have fuel pressure. if it was at zero when u did KOEO........ur fuel pump is bad!!!!!!!!!
