What is wrong
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.
What the dealer will do
Dealer will replace the fuel pressure regulator.
