Accidentally ran my gas tank dry. Add two gals and would crank but no start or even pop. Removed and replaced relay (Looked good?). still no go. Towed it home. No fuel pressure on fuel rail. checked connections on tank. They looked good. Pulled fuel line off of fuel rail. Heard relay pop while I was reinserting fuel line. Had plenty pressure immediately. I would guess pump is fine. Is it possible I had a ground issue or an air bubble of some kind? CPS issue? This is killing me. I drive this vehicle up to 200 miles from home. I would hate to get stranded. Any ideas? Thanks!
