OK so i just bought this 1988 jeep cherokee for $500 it had no spark so i changed the cap rotor and crankshaft postion sensor. Now its getting spark and fuel i checked the little valve it shot gas right out i here the pump and it still just sits there and cranks it will not start i have a little organge arrow lite that comes on when i first get in it and turn the key i dont know if that may be a problem it has all fluids in the jeep toped off and before i go on to start changing anything else i would love to hear some ideas.
