I would recommend replacing the idle air control valve. Refer to any of the many YouTube videos on this subject and you shousl have no problem replacing it. It is availabe at Rock Auto, Parts Geek and most good local parts shops.

Driver side door is used most.Check for broken wires...

Do you have the 4.3L engine with spider fuel system? That system is noted for problems. Key on engine off, fuel pressure, 60--66 psi, use a fuel pressure gage. It needs that pressure to start, after it starts, it will run with less pressure. There could be other issues? Engine cranking, you have spark at the plugs and fuel injector pulse?

it will be burnt wire and around the ignition switch burnt wires are obvious but be smart only an accredited auto electrician should be used to locate the wire/s so don't let your boyfriend start or it will cost more in the long term and will still not be fixed

Check under the hood fuse box for trailer and vehicle fuses.Use a test light and check all fuses in place.Turn ignition and light switch on when checking fuses.

Sounds like you have a bad ignition switch, not the lock cylinder but the switch itself. Electrical power should continue to go to the gauges and to the ignition module even with the key in the Start position.

Usually not. If it is shuddering while accelerating it's usually a plug wire. If you have a check engine light on then start there

Too many possibilities. You need to have a scanner that does abs systems used on it and see what the codes are. This could be anything from a faulty wheel speed sensor to a bad abs module.

You'll need to get into the door panel. It's held together with clips and screws. Find the screws in the arm rest or ? remove the screws and starting at the bottom, pry the panel away from the door carefully using a wide screw driver or ? once removed, yoll see that the window is inside the door reinforcement. It generally runs on a rail, under which is a scissors lifting arm. Sometimes the window detaches from the metal rail and can be epoxied if its loose. Use a good '5 minute epoxy' from an auto parts store, mixed well and using a popsicle stick, mix two parts together well and smear onto the metal rail which is under window assembly. Let it sit for awhile, usually 24 hrs, until well hardened. This might fix it forever. But NOW, you will have to reassemble the door panel, pressing the clips in place and replacing ALL screws that you removed. This is not the only way, but the quick and dirty way! It usually works in cases where the window bottom has separated from the scissors rail.......Cheers

Emma, Take the nozzle out a little and lower the back of the handle a little. This should stop the back pressure which makes the pump cut out. Gerry.

I had the same problem with my Impala it has to do with the security system failing. Its a very common think in GM cars. I found a part that helps bypass the problem all together.

Hope this helps ya out Do It Yourself GM Security bypass

If you have totally and completely confirmed electrical fire spark plug and wire sad part is it could be a valve or injector

Have alignment done

Fuel filter,crank shaft sensor.

The problem is probably caused by the Body Control Module (BCM) malfunctioning. This module is located under the HVAC assembly (RH side under dash). If your heater core was leaking onto it, or you damaged it during your repair, that could have caused the problems. Start by disconnecting the battery for a few minutes and then reconnecting it to see if that resets all systems. While the battery is disconnected, you can check the condition of the BCM and the three connectors (make sure they are seated properly and the contacts are not corroded). You should also scan for error codes to see if that sheds light on the problems.

modulator possible loose or faulty connection ---modulator shorting out --switch going bad ---or transfer case selector switch faulty also check fluid in transfer case

No other lights on ,dome, courtesy etc... Battery Rundown Protection/Inadvertent Power In the event that any of the interior lamps supplied voltage by the inadvertent power relay and ground from the courtesy lamp relay were to remain on when the ignition is OFF after a period of 20 minutes, the BCM will deactivate the inadvertent power relay turning OFF all of the lamps on that circuit to prevent total battery discharge. Only when the ignition switch is cycled back to the RUN position will the BCM reset the internal timer and reactivate the inadvertent power relay. When the inadvertent power relay is not energized, the BCM utilizes the inadvertent power courtesy lamp supply voltage circuit to monitor for a courtesy lamp switch request signal. If a courtesy lamp switch is activated, the BCM will receive the signal to energize the inadvertent power relay by grounding the control circuit. It maybe your radio ! It may

This is fairly normal for most all older vehicles. Things just wear down. On yours(4.3 engine) I would look to the distributor/ignition. Before the timing.
