Question Answered: How to fix a no crank no start?
April 04, 2015, 06:20 PM
A grocery list of the possibilities isn't what you need. You could guess a thousand dollars worth of parts without fixing this. Shops don't just say that there is nothing wrong, they know there has to be a problem with the car otherwise you wouldn't have brought it in. When a problem is random in nature there can be some clues that can help narrow the focus but even then it isn't a good idea to shoot from the hip, problems like this take a good game plan performed by a patient, trained specialist. One routine is labor intensive and that means connecting all of the required testing equipment and being ready to attack the problem when it occurs having pre-planned the testing routine. Another is to make themselves available to have someone drop what they are doing and come to you as long as you are close enough to them when the problem occurs so that they have a chance to start the diagnostics and begin to narrow the focus on the issue before the vehicle manages to start.
Question Answered: I have Error code p2271

The code description is O2 sensor stuck (biased ) rich, which would be a high voltage bank #1 sensor 2 as you correctly identified. It's noteworthy however that this code isn't listed for your vehicle in service information. Bank#1 is the passengers side (right hand) and the down stream sensor is after the catalyst near the transmission on the passengers side.
Question Answered: My airbag light came on will GM replace this at no cost to me?

The airbag light coming on means the computer see's something wrong with the system and it needs to be diagnosed. The first step is to retrieve the trouble code that the control module has set and then the tech has to test the circuit that the code was generated for the same way that the module tested the circuit. It is unlikely that this is going to be for free and it is up to you to have the system repaired ASAP because it is a safety system.
Question Answered: After recall for excessive key weight car still stalls while driving.

The recall dealt with the mechanical aspects of the lock cylinder being able to be turned easily under certain circumstances and essentially allowing the car to be turned off, not "stalling". The symptom you are describing has to be analyzed during an event and it often happens that it may take a number of events during which a technician makes strategic measurements in order to prove what part of the engine control system is causing the problem. It can be very tedious work and it requires that the technician have a very patient, disciplined approach. This kind of problem can be the most difficult to solve that a technician ever deals with, and oddly enough they are rarely paid for the time that they spend doing so and that's why they have stopped investigating it. Nobody can reliably just guess what is happening, it must be proven.

What code is setting? Does the light come on right away or after you drive for a while, or does it take more than one trip?

Maybe that is supposed to be U1411? If you are using a remote start the instrument cluster might not be turning on and you end up with the engine running while the computer thinks there is no fuel in the tank. Therefore "fuel level implausible" which is what the code means results. There are of course other issues that can happen such as data-bus communications failures or loss of the fuel level signal. More diagnostics with a professional level scan tool may be required.
