Hi I'm new here I just bought a 07 nitro sxt 4x4 3.7l and I'm having the issue with the starting problem. So far I've seen people mentioning camshaft position sensors crankshaft position sensors one person is already mentioned replacing the starter another one mentioned replacing injectors I know it's not the battery or the connections all the grounds are good I've had to replace one of the grounds on the engine. Has anybody found an absolute fix yet please help.
