Question about 1999 Ford Mustang Cobra
Im getting spark and injector fire and also I have a brand new fuel pump in it with good fuel pressure and injector fire Im suspecting the computer but im wondering if the maf air flow sensor would do the same thing thanks for the help
Well if it is flooding, either something is shorting out the injectors and causing them to be wide open, or one injector is stuck open, or you have a pressure regulator leaking liquid fuel into the intake.
Are all of the spark plugs wet ?
Can you start the engine if you disable the injectors ?

It might but what exactly are the codes. Before you change the Mass air flow sensor, try cleaning it first with a can of mass flow cleaner.
If your running a oil K&N filter, there could be some oil residue on the sensor. Start with that and change the filter or clean it if it's a K&N.
The O2 sensor's could be bad also, you really need the code's to be sure what sensor is giving you the faulty signal.
Good luck and hope this helps.

The fuel delivery system uses an electric fuel pump to provide high-pressure fuel to the fuel injectors. The fuel pump is located at the rear of the vehicle, mounted in the fuel tank. It can be accessed by removing the rear seat.
The fuel tubes leading from the fuel tank to the engine are under pressure during vehicle operation. When the engine is turned OFF, the fuel in the fuel tubes remains pressurized for long periods of time to provide quick start-ups. Fuel not used by the fuel injectors during operation is routed back to the fuel tank through the fuel return tube.
The fuel handling components are protected by three fuel filters. A replaceable in-line fuel filter is located inside the engine compartment between the fuel tank and fuel injection supply manifold. A serviceable filter screen is located inside the fuel tank at the fuel pump inlet. A non-serviceable filter screen is incorporated into each fuel injector.
I can get you trouble shooting tips if you want them.

it's your upper intake manifold gasket. it has a crack in it and needs to be replaced. your getting to much air and not enough gas. mine did the same thing.
