SOURCE: 1999 gmc sierra 2500 6 liter ran out of gas now won't start

If you are at or near the 100,000 mile mark then your fuel pump may have failed. If you remove the fuel filler cap and listen carefully at the filler neck while someone turns the ignition key to "run" [don't actually crank the engine] you should be able to hear the fuel pump buzz for about a second and a half as the key is turned On. If you don't hear the pump buzz then odds are your pump is dead. Your pump may have actually failed making it appear as though you ran out of fuel. Not to uncommon. Hope this helps and good luck!

SOURCE: 94 gmc sierra 4.3 v6 manual, won't turn over, can hear fuel pump start when accessories turned on..won't fire, girl who needs help

The first thing I would check is fuel pressure. This type of fuel injection requires a minimum fuel pressure in order to operate. If fuel pressure is as little as one psi below minimum the vehicle will not start. You can try squirting a couple of shots of carb spray into the air snorkel while somebody cranks the engine over. If the engine starts and then dies you now you fpdeffinetely have a fuel issue. If the engine still won't start check for spark. Let me know what you find. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

SOURCE: 2002 gmc sierra won't start, security light came on

The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. Remember too, the TDM controls the security light. Sometimes you can have ALL the symptoms and no lights.

I have a 1999 gmc sierra with (as of 30 days ago cat. converter, fuel pump and filter, cap and rotor) changed in garage. regular oil changes, tune ups as of 8 mths. it has lots of cranking power, but...


If i understand you right the truck has been sitting for two years.If it has been sitting that long without running or moving the gas has turned to varnish...I suggest that you drain and refill the fuel tank,and replace the fuel filter located on/in the frame rail on drivers side.

My truck seems to be running to rich on fuel when starting after it is warmed up, cold starts are fine. 1999 gmc


There is a possibility that your temperature sending unit for the computer is not working correctly. ( not the sending unit for the gage, there are two). If the computer never knows that the engine warms up, it will keep "choking" and over fueling. Thus, the black spark plugs.

1999 Gmc Sierra not charging


Hello;
Sounds like the alternator/regulator assembly is getting weak. The cold wreaks havoc with electrical equipment. Probably need to replace it prior to failure. Hope this helps.
