The engine compression may be low in the cylinder. If you have spark and fuel, all you need is good compression. Have the whole engine compression tested to get a general condition of the entire engine. If the compression is low in the cylinder, have a cylinder leakage test done to see where the leak is. It may be the piston rings, intake/exhaust valves, or a head gasket. If you need assistance, have a professional technician run these tests and accurately fix the problem with your spark plugs.
