Car Cranks But Won’t Start – What’s Wrong?

This is a very common problem seen in the auto repair industry. For those who don’t know what this means, a crank no start concern is when your car has power to it, and when you try to start the car it will turn over but will not fire. There are two problems that are mostly associated with a crank no start concern.

Starter is Bad.

If your starter has failed, you might get a crank no start concern. If you happen to be stranded somewhere, I would try to tap on the starter. This is an old trick used by those in the know, and sometimes it will work so you can get your vehicle to a repair facility. The reason for this is because when a starter fails, it usually binds up internally. Tapping on the starter will sometimes free the internal parts temporarily and allow you to crank and start the vehicle. If this doesn’t work, you may have lost power to the starter and will have to have the vehicle towed.

Fuel Pump Failure.

Another common problem for a crank no start concern is a bad fuel pump. A fuel pump does exactly what it says, it pumps the fuel from the gas tank through the lines and to the motor. If your fuel pump is bad your car may just crank and crank, but won’t start. Ironically a quick fix for this is the same as the starter. Try to tap on the fuel tank to get the car started. This may allow the vehicle to run on what’s called false fuel for a while, or at least until you can get it to the repair facility. If this method fails, unfortunately it’s time to get the vehicle towed.

Electrical Issues

These days most vehicles will have some form of security system in place. The most simple form of security often causes a lot of problems. If your electronic ignition switch has a security feature on it, it can fail and cause the vehicle not to start. Basically what happens, is the car thinks the wrong key is in the ignition and refuses to allow the vehicle to start. Really the only repair for something like this is to replace the entire ignition switch for faulty operation.

There can be other reasons your vehicle will crank and not start, but in my experience the two most common problems are the car getting no spark (starter) or no fuel (fuel pump).
