You need three things to make the engine run: Fuel, spark, and compression.

Which one don’t you have?

Does it every start? Does it not turn over at all, except for the occasional time? Has someone checked the battery connections (removing and cleaning the contacts at both ends or each wire? Remember to check the ground cables as well as the + cables. How was the battery checked?
