Having problems with your 2003 Chevrolet Silverado 1500 ?
2003 Silverado 4.3 V6 Powerless
\015 The pickup idles fine. But When you step on the gas it dies or it spits and sputters till it dies. I changed the spark plugs and fuel filter.\015
It sounds like you may have a couple of potential problems here. I assume that the fuel filter you replaced was the one on the exterior of the vehicle. Most GM vehicles have an outside one and one inside the tank. You may need to replace the internal one. One other problem might be your injectors are clogged, which would be likely if your vehicle was acting up for a while now and not just all of a sudden. You might also check your TPS or Throttle Position Sensor and your EGR valve.
You need to have the fuel pressure at the fuel rail checked. Sounds like a bad fuel pump.
