Engine Performance problem
1993 Jeep Grand Cherokee 6 cyl All Wheel Drive Automatic 299000 miles
93 GC Limited 4.0 is hard to start
if I just turn to run position I will not start
if I turn to on 3 times then turn to start it fires right up and then shut off and then start right up on first crank
but if it sits for an hour or over night it wont start
ive changed air filter, oil filter, oil, fuel filter, fuel pressure regulator, plugs, wires, cap, rotor
next is either o2 sensor, crank or cam shaft sensor, feul pump, or ecu
not sure what to do
any help would be great!
have the same problem?
