Details

On certain vehicles, a combination of a low battery condition and fuel in the upper intake manifold while the ignition key is activated at engine start could cause an elevated rate of manifold over-pressurization events.

The operator may experience a loud bang / intake backfire that could rupture the intake manifold, resulting in emitting dust from under the hood and a no-start condition.

If this event were to occur, and if an ignition source were present, an engine compartment fire could occur.

Correction: Dealer will replace the fuel pressure regulator.
