2004 Silverado Died!!

2004 Silverado 5.3L V8 began running very rough and misfiring. Set codes for knock sensor, crankshaft position sensor, and fuel trim lean. Replaced crankshaft position sensor and did drive cycle to relearn PCM. Ran well for a day, then while idling became rough again and misfired. Set knock sensor code again and would not start. Then lost instrument panel, radio, clock, power windows and locks, and OBD 2 port. Antilock and battery lights come on. Now none of it works, vehicle starts but dies immediately. Any ideas?

    Also, I cleaned and checked each fuel injector and replaced spark plugs and spark plug wires as well.

    You say it had codes, care to share?

  • Charles Jul 20, 2013

    As I said, it set codes for knock sensor, crankshaft position, and fuel trim lean

  • Charles Jul 20, 2013

    After replacing crankshaft position sensor it only gave code for knock sensor and then all the other things stopped working including the OBD II port

2004 chevy silverado 5.3L V8 runs rough and stalls


Well, code 336 is for a problem with the crank sensor, and code 171 is for fuel system too lean bank one which is the side with cylinder one. Since you have checked fuel pressure and I will assume fuel volume is good, the crank sensor or circuit could be at fault.

2004 Grand Pix starting running rough all of the sudden. I tuned it up and replaced the engnition module and it still running rough any suggestions?


Electronic Engine Controls WARNING
To avoid personal injury and/or vehicle damage, refer to the service precautions at the beginning of this section.
General Information The Engine Management System (EMS) uses several different sensors and actuators to gather and control various emissions and driveability aspects of the vehicle. These may include but are not limited to:
  • MAP - Manifold Absolute Pressure Sensor
  • BARO - Barometric Pressure Sensor
  • FTP - Fuel Tank Pressure Sensor
  • ECT - Engine Coolant Temperature Sensor
  • A/F - Air Fuel Ratio Sensor
  • APP - Accelerator Pedal Position Sensor
  • CKP - Crankshaft Position Sensor
  • CMP - Camshaft Position Sensor
  • EGR Valve Position - Exhaust Gas Recirculation Valve Position Sensor
  • HO 2S - Heated Oxygen Sensor
  • IAC - Idle Air Control Valve
  • IAT - Intake Air Temperature Sensor
  • KS - Knock Sensor
  • MAF - Mass Air Flow Sensor
  • TP - Throttle Position Sensor
---
Are there any codes that point to a problem with any of the above sensors?

4.3 vortec runs OK cold, runs rough or dies warm


replace the CKP and the truck will need to go to a shop and have the "crankshaft variation relearn" performed. the misfire may or may not go away, and that will need to be addressed also.

High idle stalls at lights code for crank sensor


Crankshaft and Camshaft Position Sensors Camshaft Position Sensor Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:
  • Extended crank time with a cold engine
  • Intermittent rough running
  • Unstable idle
  • Bucking
  • Hesitation
  • Stumble
  • Chuggle
  • Poor fuel economy
  • Stalling on acceleration
Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms: No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit
