Why does my Acura MDX start then shut off?

Possible Causes for Acura MDX Starting and Then Shutting Off
There can be several reasons why an Acura MDX starts and then shuts off. Here are some possible causes based on the search results:
1. Bad Gas: If your MDX shuts off a few minutes after you last filled it up, bad gas could be the issue. Gas can go bad with age or if it has been sitting for an extended period. Old gas can contain deposits that cause the engine to shut off. Draining the fuel tank and replacing the gas may help in this case.
2. Intake System Issues: Check all the hoses in the intake system and make sure the clamps are tight. If a clamp comes loose, it can cause air rushing in and lead to the engine shutting off when slowing down or stopping.
3. Ignition Switch or CPS Failure: While the failure mode of an ignition switch or crankshaft position sensor (CPS) tends to be more gradual, they can still cause the engine to shut off. Ignition switch failures are usually mechanical and occur when operating the switch, while CPS failures can be intermittent and initially cause the engine to run badly.
4. Battery, Alternator, or Starter Issues: Problems with the battery, alternator, or starter can also prevent the MDX from starting or cause it to shut off. If the engine cranks slowly or doesn’t crank at all, a weak or dead battery is a likely culprit.
5. Electrical System Faults: Faults in the electrical system, such as a blown fuse or immobilizer error, can disrupt the starting and running of the vehicle. These issues may require further diagnosis and repair.
It’s important to note that these are potential causes based on the information available. To accurately diagnose and resolve the issue, it is recommended to consult with a qualified mechanic or take the vehicle to an authorized Acura service center.
