Question about 2007 GMC Sierra 2500HD

Open Question

I have a 2007.5 GMC Sierra HD LMM turbo diesel. This morning I went to use the auto start function on the key FOB and nothing happened? I put the key in the ignition and everything came on electrically but when I turned the key it would not turn over. Is this a dead battery situation or could it be something else?

SOURCE: 2007 gmc sierra 2500 IAT sensor

Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

As long as there is not damaged areas, and all connections are the same. Should work.

SOURCE: I need to replace the fuel filter on my 2003 GMC

ITS A SPIN ON FILTER, YOU NEED TO DISCONNECT THE WATER SENSOR ON THE BOTTOM OF THE FILTER, THEN USING A STRAP FILTER WRENCH LOOSEN THE FILTER AND SPIN IT OFF.

CHECK THE FILTER HOUSING TO BE SURE THE INNER FILTER SEAL ISN'T ON THE HOUSING AND CAME OFF WITH THE FILTER.

REMOVE THE WATER LEVEL SENSOR AND DISCARD THE SEAL.

INSTALL THE WATER LEVEL SENSOR ON THE NEW FILTER. USING A LITTLE GREASE ON THE INNER FILTER SEAL AND ON THE OUTER O-RING TO HOLD IT IN PLACE, SPIN ON THE NEW FILTER.

OPEN THE VENT ON THE UPPER SIDE OF THE FILTER HOUSING. PUSH DOWN ON THE HAND PUMP QUICKLY UNTIL THE FUEL IS COMING OUT OF THE VENT. CLOSE THE VENT AND PUMP THE FILTER PUMP UNTIL IT FEELS SOLID. AT THIS POINT START THE ENGINE. IF IT STALLS PUMP IT UP AGAIN AND RESTART THE ENGINE. IF YOU HAVE AN ASSISTANT THEY CAN PUMP THE FILTER PUMP WHILE THE ENGINE IS RUNNING AND QUIT WHEN YOU FEEL THE ENGINE IS NOT GOING TO STALL. ABOUT 10 TO 15 SECONDS USUALLY WORKS.

CHECK FOR LEAKS.

BEFORE STARTING THE ENGINE USE BRAKE WASH TO REMOVE THE FUEL SPILLED DURING THE FILTER REPLACEMENT. ALLOW IT TO DRY BEFORE STARTING THE ENGINE.

RATE ME PLEASE.

SOURCE: I changed batteries in my 2003 GMC Sierra key fob

1. Close all doors
2. Insert key into ignition
3. Hold down the power UNLOCK button on the driver's door panel, continue to hold down
until instructed to release in step 9.

4. Perform steps 5 through 8 in a fairly rapid succession.
5. Turn the ignition to the ON position (as far as you can go without starting the engine.)
6. Turn the ignition to the OFF position.
7. Turn the ignition to the ON position (as far as you can go without starting the engine.)
8. Turn the ignition to the OFF position.
9. Release the power UNLOCK button on the door panel. The vehicle should respond by
door locks locking and unlocking automatically. (If locks do not cycle after you let go,
not before you let go of the unlock button, then the vehicle has not entered programming
mode and you must start procedure over. Remove key from ignition, open drivers door
and return to step 1 ). If the locks do cycle automatically then proceed to step 10.

10. Hold down the LOCK and UNLOCK buttons on the remote until the doors lock and
unlock. This may take up to 30 seconds.

11. Repeat step 10 NOW for each additional remote. (Including any existing remotes).
12. Turn the ignition to the ON position to exit the programming mode.
13. Test remote(s).

Park lights come on in a2008 gmc 2500 hd diesel when left parked not running factory remote start just died also any suggestions


lights stay on for short time after turning off vehicle or when you hit lock or unlock on fob as to auto start either fob battery died --fob malfunction--or you have a check engine code --have vehicle scanned because a pending trouble code may not light up on dash but will disable remote start --if it is a fob problem and you lost programming need to go to a dealer to flash the remote start

Try jump starting it. I suspect your battery is dead. After time they don't hold a charge as deep as they once did. Have it load tested to verify. Your lights and other options don't draw nearly what your starter needs.
