Starter cranks but engine will not start

Knowing the year motor size and mileage would of made it easier to help so please included it next time. :) Does the car have spark. If the motor cranks and you have fuel and spark then its the timing. If your car has a distubutor you can check if the timing is off using the following method. Remove the cap and observe the postion of the rotor. Turn the motor slowly by either tapping the key or by hand. If turning by hand turn it clockwise. When the rotor is pointing toward the number 1 tower on the cap,check the hormonic balancer to see if the timing marks line up correctly. For example if the timing is 8 degrees BTDC then the markings should be on or near that. If its off by alot then the chain has slipped and needs to be replaced. The only other way the timing come of gone off is if the distubutor is loose. Make sure it's tight first. Good luck
