It could be or your fuel pump could be weak, fuel filter could be dirty, need a tune up? Lots of things can cause those problems.... If you need further help, I’m available over the phone at https://www.6ya.com/expert/justin_3ae27a9d61d6acd4

Many things;bad wires or cheap,plugs,coils,fuel filter.

Have you replaced the fuel pump recently. If not have the fuel pressure checked.

common problem would be a clogged up fuel filter.

The head lamp assembly should be sealed, you can either replace them or...... remove them and drill a small hole or two in the bottom to allow the moisture to exit. I have done this on a number of vehicles and it works great

Did you change the fuel filter? also did you clean the inside of the MAF sensor w/ MAF spray cleaner?

could be hose are a freeze plug are water pump.determen where the leak is on the floor and go from there

need to replace tha ac door actuator plastic gears in side break and the ac or heat wont switch with the controls

Had that been there,you need a shift lock actuator,the real name is shift interlock solenoid its is located RH side of steering column , under support bracket

follow the steps and fix it. God bless you Start the engine and let it to run for a few minutes to allow the air to cool. Double check the controls to make sure the correct buttons are selected. This may seem simplistic, but human error could be to blame.

2 Adjust the climate controls. If they are working correctly with the right amount of resistance and stopping at the right places but have no effect on the air then it is probably a simple fuse problem. If they are not working correctly then it is probably a control panel issue.

3 Get to the fuse box to change the blown fuse in a GMC Sierra by opening the driver's side door and prying off the trim panel to the left of the steering wheel. The fuse can be removed with your fingers. If the Sierra was purchased new there should be replacement fuses in the fuse box.

4 Check the control panel next in your GMC Sierra. Remove the trim plate bezel surrounding the center instrument panel. Pull of the storage tray and the accessory switch.

5 Unscrew the four screws holding the climate control assembly in place, push in the retaining tabs and pull the control panel out. Unplug the electrical connector. Sierra models older than 2001 have no retaining tabs or accessory switch.

6 Listen for the blower motor while the engine is running and the air is on. There are two different possible blower motors in a GMC Sierra. Both are easily accessed from under the hood. The Delphi will sit vertically, while the Visteon sits horizontally. In both cases, remove the sound insulation panel, unplug the electrical connector and unscrew the three screws holding the blower motor into place.

All these accessories are controlled through a central module called the BCM which in turn activates relays and circuits. What must be done 1st is to have the BCM module tested for proper operation by running an active test on it, it will operate the accessories and report back what it sees is a problem in the form of a message on the scan tool. Also check all the fuses with a 12 volt test light to make sure they are good and are receiving power to the circuit, you could have a defective ignition starter switch as well. Refer to the owners manual for systems that affected relays and fuses locations. If you don't have an owners manual you can download one free HERE after you register with the GM owners site

First off the gas thing might just be coincedence, second sounds like an alternator problem to me. Try this make sure you do not leave any lights or doors open for the battery to drain at night, Make sure your battery terminals are clean and tight, then to test to see of it is the alternator start the engine and with it running disconnect the battery terminals. I can not remember if it is the positive or the negative terminal to disconnect, so carefully start with the positive then the negative terminal and disconnect them from the battery. Be sure to not let the terminals touch any metal while one side is still connected to the battery. If the alternater is bad the car runs only on the charge of the battery, so once the terminals are disconnected from the battery the car will die. If it stays running then the alternator is good. Then I would look at the starter, TO be honest the only way I can truly diagnose the problem is to see for my self. To see if there are any noises, signs of other issues, Or clues that would help rule out the number of possibilietes.Hope this helps

My first guess would be the key switch is faulty.A mechanic would test the circuits at the switch.

Yes could be spark plugs, cap rotor or wires.

Your problem is very unclear, please re-post it in clearer and easier to understand terms. Also you you checked for electronic fault codes in the control modules memory? Thanks for you cooperation.
