for seveal months, my low fuel light has been going on and off even though i have a full tank of gas. now my check enging light keeps going on and off. i took it to auto zone and they put the machine on it and the code is p0452. fuel tank pressure sensor condition. connectors, wiring, hoses and fittings are ok. so, does this mean that i need to replace my fuel pump?

  no, code numbers never identify bad parts, just a failed system. you need a shop with a scan tool, smoke machine and voltmeter to manipulate the system and pinpoint the failure. it is a time consuming job.

• Transmission shudder?
  ...ly in my 2005 Silverado (4L60E reman by Jasper, under 10k), feels like a miss but don't have a check engine light, checked for trouble codes anyway and didn't have any. Does this sound like a tranny problem?
