One guy I know traced it to his in-tank fuel pump. The computer reads that all of the electronic components of the pump are running at optimal, but a pressure gauge connected to the fuel rail on the intake showed the pressure was 58 psi at an idle and it dropped to 45@ 2000 rpm's. 58 psi is minimal for a big block, 60 is optimal. The book shows the small block should be around 50 to 55 psi for optimal pressure. The drop in fuel pressure causes the engine to lean out under a load such as accelerating and pulling and could cause the engine to burn a piston from the increased cylinder temp. I am not certain how this would cause ignition power loss though, unless that fuel pump has a safety cut out for electrical shorts, real or perceived by the computer.... Have to talk to some friends about that.

Try locking and unlocking the drivers door with the key

it is the fuel pressure regulator that is responsible for running the fuel pump as the pressure varies the regulator tells the ECM to turn on/off the relay to the pump

no the oil travels with the gas and collects in the compressor and the receiver / drier

Remove the breather box, this will give you access to the bulb. Turning counter clockwise and remove.

What code's ? # code's P0 what ? Any BCM - body control module code's ? Did you do diagnostic test's for said code's ? Do you know what a factroy diagnostic flow chart is ? Is the vehicle a 4X4 or 2X4 ? What engine ? Do you know what class 2 serial data bus is ? Do you have wiring diagrams ? Headlamp ON/OFF control is determined by the body control module (BCM) by a signal on the headlamp switch headlamp on signal circuit when the headlamp switch is in the HEAD position. When the headlamp switch is in the AUTO position, the BCM determines headlamps ON/OFF by the voltage from the ambient light sensor. High Beams The high beam headlamps receive voltage from the headlamp HI relay located in the underhood fuse block. The body control module (BCM) controls the relay on the headlamp high beam relay control circuit. High beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamp dimmer switch signal circuit is grounded, the BCM grounds the headlamp high beam relay control circuit, illuminating the high beam headlamps. The right and left high beam circuits are independent and are fused independently in the underhood fuse block. The right and left headlamps are grounded at G100 and G104. The high beam indicator is illuminated when the instrument cluster receives a class 2 serial data message from the BCM that the high beams are illuminated. Low Beams The low beam headlamps receive voltage from the headlamp LOW relay located in the underhood fuse block. The body control module (BCM) controls the relay on the headlamp low beam relay control circuit. Low beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamp dimmer switch signal circuit is open, the BCM grounds the headlamp low beam relay control circuit, illuminating the low beam headlamps. The right and left low beam circuits are independent and are fused independently in the underhood fuse block. The right and left headlamps are grounded at G100 and G104. DTC B2645 The body control module (BCM) monitors the ambient light sensor signal circuit in order to determine if the daytime running lights (DRL) or the auto headlights (ALC) should be turned ON in the AUTO mode. When the BCM senses the ambient light sensor signal voltage is between 1.75-4.9 volts, either the DRL will be commanded ON or the ALC will be commanded ON depending upon the amount of light received by the sensor. DTC B2645 Ambient Light Sensor Circuit

Disconnect the cables again and touch both together for about 1-min to reset computer and body control module. Connect the pos cable first, negative cable last

Check the sending unit?

try reformatting. Windows has it built in. File explorer selct device right click and select format

Your best bet is to call a local parts store and ask this question because some are some are not they can look it up for you no problem.

Miss cud b from worn injector. Sensor from tempgauge mite b bad. Get car scand

that depends if u have a 4l80 or a 4l60 need more info.

There is none, not available. Timing is control by the PCM (Powertrain Control Module)Therefore it can be check with a scanner. There is a procedure when you change or replace a distributor or any engine repair.Hope it helps

52 ft lbs, body mounting bolt.

It sounds like you have a short to earth

http://www.winjetinc.com/pdf/winjet_foglights_wiring.pdf Found this info. Don't know if that is what you wanted? Do you want diagram for 07 Silverado lamps?

Any DTC"S - diagnostic trouble codes ? The charging system on that vehicle is computer controlled . Are You Smarter Than Smart Charging System MOTOR
