So, you are hearing all the same noises as usual when trying to start your car.

But, the one big difference is the engine will not start.

Knowing this information does help narrow down the list of possible problems.

Consequently, If your engine turns over normally but will not start, you have already eliminated the battery and starter from the list of possible problems. Hence, the battery is making the starter turn properly.

No Spark – When Your Engine Cranks But Fails To Start

If the engine turns over but will not start, check the basic things first:

  • The computer in modern vehicles monitors and controls a good number of sensors and actuators. Scan your computer memory for trouble codes before you do anything else. Even if the check engine light hasn’t come on, you may find a pending code that can guide you in your diagnosis.
  • False input or lack of input from sensors like the crankshaft position sensor (CKP) or camshaft position sensor (CPS) can prevent the engine from starting.
  • Also, a bad throttle position sensor (TPS) may cut off the spark to the cylinders.
  • Check for a blown fuse that may be preventing a circuit from working properly, like the fuel injection or computer system.
  • If the car doesn’t start with the automatic transmission in “Park,” does it start in “Neutral”? Sometimes a car won’t start in “Park” but starts in “Neutral” because of a problem with a neutral safety switch.
  • Do you think there enough fuel in the tank? It’s a common situation when the fuel gauge isn’t working properly and the car runs out of fuel with the fuel gauge still showing some fuel left.
  • Is the “Security” or key-shaped light in the instrument panel stays on or blinking? Does your car have an anti-theft system that for some reason doesn’t allow the car to be started?
