Chevrolet Truck stalling out

Asked by GuruVG6CT Sep 25, 2018 at 10:40 PM about the 1999 Chevrolet Silverado 1500 Extended Cab 4WD

Question type: Maintenance & Repair

Any ideas why my truck is stalling
out. If able to get it to start when I
mash on the gas it's like it floods
itself out. Won't take the gas pedal.
Have replaced the fuel pump, fuel
filter,throttle sensor,mass flow air
sensor. Don't know what to do next.
Please help asap. Thanks

Before replacing any more parts, scan for fault codes and see what's really going on. My guess is that the spark plugs are shot or some other ignition problem...weak spark.
