order a new frame assembly , this type of component isn't made to be repaired , just like most components on moder cars

The oil pressure switch screws into the top of the filter adaptor on the 3800 engine. Good chance it is the problem.

Check the tag inside the glove box door or in the trunk on the spare cover for code

bad inner axle joints.

This is common for inner axle shaft joints had a bad worn spot in them so as you accelerate these joints need to slide in & out freely there are binding.

the license plate light is part of parking lights it is power by parking lights.does your parking lights works if yes look for bulbs or wiring in trunk. hope it helps

Without knowing the year of your vehicle, I can only assume that a component, probably the ignition control module is getting too hot. This could be the module is bad or the resistance between the coils and the spark plugs is too high. Check the resistance in the ignition wires to see if they are within specs and check the spark plugs themselves. A new module could solve your problem but, if the cause of its predecessor's failure is not fully addressed.it could happen again.

Tell the technician to sell his tools and but a frankfurter cart!! A real tech does not changed anything unless he is absolutely sure it is the problem. There are many reasons a vehicle will not start. Too many to list but having parts changed until the vehicle is repaired is not the way to do it. You vehicle probably has a 3.8L engine. These engine were known for CPS (crankshaft position sensor) problems. Tell your 'tech' to check for spark, injector pulse and fuel pressure and DON'T PAY HIM FOR THE MODULE. Insist he re-installs the old one to do the diagnosis.

Sounds like the fuel pressure regulator. if you have access to a pressure guage check the pressure when it will not start.

Is there any item got replace lately?
What is the current odometer reading?

=== Let's rule out the fuel pump relay and fuel pump.
Fill up the tank to above 3/4 with Chevron gas and one bottle of Lucas fuel system cleaner. A weak / failing fuel pump will use more current to pump the fuel when the fuel is low (below 1/4 tank)
The fuel pump relay will get hot because of high current draw and damage the fuel pump relay.
After start up,please check the temperature of the fuel pump relay.
============= Next item to check is the GM security key and neutral safety switch,
Use the spare key to start the car.
Check for loose key ring sensor.
===
With brake on,shift the gear selector to N for neutral.
Start the car.
Put the gear selector to Drive and see is the engine stalling.
===
Please do the inspection in the morning so I will have the whole day to follow up on the case.
You can append comment on the post.
I will reply my recommendation via email.

relay switch is bad . it should be located under the hood driver side fender well.

If something is wrong with the speed,then the transition needs repair/replacing.Most likely.

I believe that there are 2, 3, or 4 screws holding the bag assembly to the steering wheel. You can remove the screws from the back of the steering wheel. Be careful handling the airbag. Be sure to disconnect the battery completely, take the battery out of the car.
