So I got a 95 civic hatchback with a gsr in it. I replaced the starter,check all ground, good battery and change main relay but still nothing. The car is weird because it would start 1/3 (1 outta 3) times but most time it won’t start. The car easily starts when jumped by another car so I’m very confused. It starts sometimes but won’t start most of the time and start easily when jumped so please help me.

 

need more details, is the starter cranking the engine but the engine won't run or is it not cranking at all?
