Check for loose or corroded ground wire even if the bolt seems tight I would remove it and clean the surface. Make sure the mounting surface for the starter motor is clean free of rust it is very important since the body of the starter provides the ground for the motor. Check you ground and positive battery cable make sure is not corroded if there are signs of white stuff (corrosion by battery acid) on the tip of the cable more than likely the entire cable is bad corroded, corrosion causes resistance to the point of causing that problem. Make sure the engine is not seize up get the necessary tools to try to rotate the engine by hand, it should be hard but smooth you should be able to do it with one hand if you have to lean or pull with a lot of force for it to move then you have bigger problems. Hope it helps Good luck|||With out possible help, I wonder how you changed the starter. Any way, assuming there is sufficient fuel, battery charge, clean air filter. Try push start the vehicle. If it does, check the flywheel else check the spark.
