Cranks but will not start

Hello,

Even though the lights come on, the battery may not have enough power to start the engine.
You should first get the battery tested, in case this is bad.

The second item needs to be checked is the starter. As when you do a rolling start you bypass the starter to start the car.

Please let me know of any questions.

Thank you.
