having trouble starting my suv
I have a 2002 ford Explorer,that is giving me trouble starting.most of the time it will start but every couple of days it will crank but not start.But once we jump it.it starts right up,and is good for a few more days.I had the battery checked it's at 100 % we checked the alternator by removing the cable it stayed running so the alternator is good.I put new battery cable connectors on.I've been told to change the fuel filter,so thats my next adventure.I really need help I am disabled and I have no one to help me so I am watching videos to do this on my own,So I could really use the advice on what it might be.
