The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Inspect for any air leaks near the MAF sensor.
* Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
* Check the voltage of the MAF sensor
The fuel pump and the MAF sensor are not related.
Check the fuel pump relay and its ground.
check fuel pump prime connector(see diagram).
Check the hot fuel module ground, as fuel pump gets it power from the relay through that module, make sure it has good ground.
check connector between FP relay ,Hot fuel module and fuel sensor/oil pressure.(see diagram in your email for details)
