SOURCE: hard start

Its your fuel pump.I had the same plomblem not too long ago.I was spraying either in to start it.I have a 97 chevy truck witch requires 65 psi to start and 55 to run properly.You need to find out much psi you need to start it.You can probaly look in your manual or just make a few calls.My truck had 55 psi and it ran fine i just had to get it running first.Good luck.I wonder if that fuel pressure regulator was a waste of time like it was for me.

SOURCE: 1999 chevy silverado 4.8 1500 will star but not idle

Could be as simple as your fuel filter...after the truck starts..can you keep it runing by gunning the motor?

If you can feather the accelerator to keep the motor runing, I'd start at the filter, and then check the fuel pump

You probably have way too much unburned fuel in your exhaust system (how's your mileage?) or possibly a failed oxygen sensor that is giving false information to the computer.

SOURCE: what is a 5 Volt Reference Circuit ?

a reference circuit is a reduced voltage(less than 12) that is current controled
without it your car may suddenly accelerate smply by you turning
your heater or Ac on (the battery voltage changes )
it's used on many cars for the sensors like the throttle posisition
or Map
if the fault code says you lost it
you got a shorted wire or sensor somewhere on the engine

consult your vehicles engine wire diagram to see what sensors run on 5 volt ref
then start lookin and unhookin
(chiltons avail in most public librarys has a good wire diagram)

Dtc po340 wont start put in new cam sensor still just cranks 42lbs fuel pressure at shrader valve has spark at plugs only code was po340 help


P0340 - Camshaft Position (CMP) Sensor Circuit Malfunction ,did you check the wiring ?
P0340 - Camshaft Position (CMP) Sensor Circuit Malfunction The test fails when the PCM can no longer detect the signal from the CMP sensor.
  • CMP circuit open
  • CMP circuit short to GND
  • CMP circuit short to PWR
  • SIG RTN open (VR sensor)
  • CMP GND open (Hall effect sensor)
  • CMP misinstalled (Hall effect sensor)
  • Damaged CMP sensor shielding
  • Damaged CMP sensor
  • Damaged PCM
Harness routing, harness alterations, improper shielding, or electrical interference from other improperly functioning systems may have intermittent impact on the CMP signal. DR1 DTC P0340: CHECK IF ENGINE WILL START
    Note: Refer to the Pinpoint Test Schematic to determine the type of CMP sensor.
  • Start engine.
Will the engine start? Yes No GO to DR2 . DTC P0340 is not the cause of the No Start. GO to Section 3 to diagnose the No Start symptom. Is the PCM firing the injectors ?
  • Starting Concerns:
    • No Start, Normal Crank
Note: Extended cranking because of a no start can load the exhaust system with raw fuel, damaging the catalytic converter after the engine starts. For applications with Secondary Air Injection (AIR) Systems, perform the following after the no start has been repaired: Disconnect the electric secondary air injection (AIR) solid state relay, run the engine until the surplus fuel is used up, and reconnect the relay (disconnecting the relay may set a Continuous Memory PCM DTC that will need to be cleared).


SYSTEM/COMPONENT REFERENCE (Section 5 Pinpoint Test unless noted)
  • Add-on Anti-Theft Devices
  • Visual, check with customer.
  • Fuel/Ignition
  • For LS6/LS8:
  • GO to KB85 .
  • All others:
  • GO to A1 .
  • If engine is now a no start:
  • If engine will start and run normally at part throttle, check Idle Air Control (IAC) System.
  • Engine will now start and run normally at part throttle:
  • GO to KE2
  • Exhaust System (restrictions)
  • GO to HF1

What is the fuel pressure specs on a Chevy cobalt 2.2 ecotec 2009


I don't know the exact pressure but 55 psi sounds good to me. Most ordinary passenger cars run at about 2 bar with something like a 5 psi increase for acceleration.
A pressure test isn't a lot of use on its own as it is possible it can provide the pressure when no demands are placed on the engine but not deliver the volume of fuel needed when demands are made. A peak pressure test and a flow test would ensure the fuel system is good.

I am wondering if the egr valve is on the same side as the lean bank? Dodgy egr valves are a big cause of bad running.

After a stop, 2003 GMC Safari act like gas filter or catalityc converter is plug. No power at all, then, 5 seconds later I start rolling, vehicle will get the normal power and kick in. Got code 0016 on...


The power-train (ECM) supplies a 12-volt reference circuit and a low reference circuit to both the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor. The CKP sensor sends a signal to the PCM with each revolution of the crankshaft. The CMP sensor sends a signal to the PCM with each revolution of the camshaft. This diagnostic (DTC) monitors the CKP signal and the CMP signal to determine if they are synchronized. If both signals are not observed by the PCM within a narrow period of time, the PCM will determine that an error has occurred and DTC P0016 will set.

How do i change the crank positioning sensor on a 8.1 liter chevy silvarado?


Crankshaft Position Sensor: Service and Repair
Crankshaft Position (CKP) Sensor Replacement
REMOVAL PROCEDURE
IMPORTANT: Care must be taken when removing the crankshaft position (CKP) sensor. Use penetrating oil and allow to soak around the CKP
sensor before removing the sensor. Twist the sensor to break the O-ring seals loose. When removing the sensor, pull the sensor straight out of the
engine block at the same angle the sensor was installed. Failure to be careful may result in sensor damage.
1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle.
2. Disconnect the crankshaft position (CKP) sensor harness connector at the CKP sensor.
3. Remove the fuel line bracket and retaining bolt.
4. Use penetrating oil and allow to soak around the CKP sensor before removing the sensor.
5. Remove the CKP sensor retaining bolt.
6. Prior to removal of the CKP sensor, rotate the sensor back and forth.
7. Remove the CKP sensor at the same angle at which the CKP sensor was installed.
INSTALLATION PROCEDURE
IMPORTANT: Inspect the CKP sensor O-ring for wear or damage. If a problem is found, replace the O-ring. Lubricate the new O-ring with engine
oil before installing.
1. Install the CKP sensor at the same angle at which the CKP sensor was removed.
NOTE: Refer to Fastener Notice in Service Precautions.
2. Install the CKP sensor retaining bolt.
Tighten
Tighten the bolt to 12 N.m (106 lb in).
3. Connect the CKP sensor harness connector.
4. Install the fuel line bracket and retaining bolt.
5. Lower the vehicle.
6. Perform the CKP System Variation Learn Procedure. See: Testing and Inspection/Programming and Relearning

fdb4314.jpg

Crankshaft Position Sensor: Service and Repair
CKP System Variation Learn Procedure
IMPORTANT: For additional diagnostic information, refer to DTC P1336.
1. Install a scan tool.
2. With a scan tool, monitor the powertrain control module for DTCs. If other DTCs are set, except DTC P1336, refer to Diagnostic Trouble Code
(DTC) List for the applicable DTC that set.
3. Close the vehicle's hood.
4. With a scan tool, select the crankshaft position variation learn procedure.
5. Observe the fuel cut-off for the engine that you are performing the learn procedure on.
6. The scan tool instructs you to perform the following:
^ Apply the vehicles parking brake.
^ Block the drive wheels.
^ Cycle the ignition from OFF to ON.
^ Apply and hold the brake pedal.
^ Start and idle the engine.
^ Turn OFF the A/C.
^ Place the vehicle's transmission in Park (A/T) or Neutral (M/T).
^ The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. The scan tool only
displays the condition that inhibits the procedure. The scan tool monitors the following components:
- Crankshaft position (CKP) sensors activity - If there is a CKP sensor condition, refer to DTC P0335 or DTC P0336.
- Camshaft position (CMP) sensor activity- If there is a CMP sensor condition, refer to DTC P0341, DTC P0342 or DTC P0343.
- Engine coolant temperature (ECT) - If the engine coolant temperature is not warm enough, idle the engine until the engine coolant
temperature reaches the correct temperature.
7. With the scan tool, enable the crankshaft position system variation learn procedure.
IMPORTANT: While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is
returned to the operator and the engine responds to throttle position after the learn procedure is complete.
8. Slowly increase the engine speed to the RPM that you observed.
9. Immediately release the throttle when fuel cut-off is reached.
10. The scan tool displays Learn Status: Learned this ignition. If the scan tool does NOT display this message and no additional DTCs set, refer to
Symptoms - Engine Mechanical. If a DTC set, refer to Diagnostic Trouble Code (DTC) List for the applicable DTC that set.
11. Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.
