Stops running going down the highway strong gas smell let it run out of gas and now it won't crank
Check your fuel rail for pressure... If none turn key on.. if still no pressure you have a faulty fuel pump

Fuel pump is in tank, but ck the crankshaft sensor front of engine near pully for proper connection

Your PATS security system is faulty...check the BCM up above the glovebox...Seems I've told you this before?
SOURCE: Fuel leak (smell is in the passenger vent) but cannot be located.
sounds like it could be a leaking fuel rail. you should fix this very soon. if it is it is a fire hazard. that is if it is under hood and not underneath. look under vehicle and check for wet spots.

The rear leveling trip switch is located on driver's side near rear air shock on the frame. Check for leaks in air line.
