does it turn over?? check coils or coil packs.

behind head light,, on passenger side, on fenders underside ,remove head light completely,, drill 2 inch hole into protective shield, this will expose switch

fuel pump may be out but you have to drop the tank to fix it

IF IT IS A I6 CHANGE THE CRANK SENSOR

This is usually a sign of the battery wires not connected completely or the ground has become frayed and needs to be replaced.
