GMC Jimmy Tailgate Glass- Vandura Wont Start

Question:
2000 GMC Jimmy. The tailgate glass is stuck closed on my truck. The mechanism can be heard firing inside the door when the electronic buttons that open the glass are pressed but the glass does not pop open. There seems to be no way to access the inside of the tailgate unless it is actually open, so i am just curious if anyone knows what might be involved in getting this open, if it sounds like something best suited for a GM tech or if this sounds like one of those things i should just go to a junk yard get a new interior for the tailgate and let any old mechanic tear it out fix it and replace the interior.

Answer:
Ya, that is a real bad set-up. Sometimes we can get the panel off without breaking it, but not always. At best there will be a crack at the bottom where you pull to try to get it off. You would pay probably 1 hour labor for a GM tech to try, then he may break it. So getting a price on one from a junkyard, then doing yourself may be much more economical.


 

 

That way you will have the panel on hand if it does break. Or just go ahead and destroy the old panel if you can find one that is cheap enough. Once it is off, you can then either loosen the latch to open the tailgate or use a screwdriver to pop open the latch. There will be two rods that go from the center outward to the latches on each side of the tailgate. You will need to move the mechanism in order for those rods to move and release the gate.

Question:
THE ENGINE IS TURNING, BATTERY IS OK, FUEL PUMP IS WORKING, AND THERE IS NOT FUEL COMING OUT FROM THE TWO INJECTORS ON TOP OF THE INTAKE OR CARBURETOR. THE CHECK ENGINE LIGHT IS ON FOR SEVERAL MONTHS BEFORE. 1995 GMC VANDURA 2500. Engine size: 4.3L Vortec. Warning lights: CHECK ENGINE.

Answer:
From what you describe, you may have either lost the fuel injector signal, or the fuel injectors themselves are bad. You check to see if you're getting a signal from the PCM to fire the injectors by using a test light across one the injector connectors at a time.

One wire is hot from a fuse, the other is the ground side that the PCM controls. They are big enough connectors that you can test easily. Connect one end of the test light to one terminal and the other end to the other terminal and have someone crank the vehicle.

The test light should flash if you're getting a signal. If there is no flash, you probably have a faulty PCM (powertrain control module). If the test light does flash, re-connect the injector and check again for fuel. If none is being pulsed out of the injector, it could be clogged or the solenoid inside it could be bad or stuck. Check for any other fuel line restrictions such as a kink in the line, clogged fuel filter, etc.
