Having problems with your 2003 Chevrolet Suburban 1500 ?
Engine cranks don't start it is firing filters are good i was told it was the airflow sensor
I have had the same issue. Not enough fuel pressure from the pump. Replaced pump and all is good. Just to be sure you can install a gauge to verify pressure
