There are a number of potential reasons why the Chevy HHR might crank but fail to start. One common culprit that comes to mind is a weak or dead battery. To check if the battery is the issue, you can remove it and bring it to an auto parts store for a free test. Another possible cause could be a faulty ignition coil. Even if you replace the battery, alternator, and starter, the car may still not start if the ignition coil is bad. The ignition coil plays a crucial role in increasing the voltage from the battery and sending it to the spark plug for igniting the gas. If the coil is malfunctioning, the gas may not ignite, resulting in the engine not starting.

If your HHR isn't receiving the necessary fuel, it could indicate issues with the fuel filter, fuel pump, or fuel injection system. Without the right amount of fuel reaching the combustion chamber, the HHR may crank but fail to start.

Here is a paraphrased and rewritten version of the text:
Try these basic steps when troubleshooting a fuel pump relay issue: swap out the relay with another one, inspect the fuses, and if you have starting fluid, spray a small amount into the air filter. If the engine starts, the problem is likely fuel-related. If not, it may be necessary to visit an auto shop equipped with a professional diagnostic tool to further diagnose the issue. -
If your HHR is cranking but not starting consistently, but runs perfectly when it does start, try replacing the fuel pump relay located under the hood.

My 2008 Chevy HHR is having starting issues, and we suspect it's due to the key being stuck in the ignition. We've tried various methods to remove it but have had no success. We've replaced multiple components, except for the engine itself.
