We've checked the spark plugs and wires..it's getting gas.. it will turn over but it won't crank
If it has spark gas and air going into the engine then you must have a mechanical problem with the engine like a timing chain or belt (depending on engine) that has failed or the fuel is not being injected into the engine. have you tried spraying starting fluid into the air intake to see if it fires up. By the way "won't crank" to a mechanic means the starter isn't spinning the engine over, do you mean to say will not fire up?.
Just because it get fuel,but does the fuel injector pulse? Add fuel in the throttle body if it wants to start your problem and solution will resie in bringing the fuel injector to working level

The MOST LIKELY cause of your problem is a failed distributor module. (inside the distributor) The symptoms you described can also be caused by many other things like loose or corroded connectors or even a failed Powertrain Control Module (PCM)

What Else Could Be Wrong?
SOURCE: The reason I'm checking the timing belt is that
unplug the fuel injectors, check the olhms on all. the readings should all be the same, around 11-11.5 olhms. Any readings that are higher is a sign of a bad injector which is what your problems sounds like., putting to much fuel to a cylinder causing different fuel amounts to each cylinder and causing it to backfire out of the throttle body , excess fuel . Also remove the throttle body and clean with cleaner and a toothbrush after replacing any injectors. Or there's a simpler answer and that the cambshaft is worn-out/round causing the lifters not to open enough to let in all the fuel. A worn belt would not cause misfires only on select cylinders but rather jump timing, slipping a notch on a gear and possibly bending a valve or valves and this cause a loud clacking or a really a sign to quit running the motor because it's broke! Good luck.
