I have a 95 cherokee sport 6cyl 4.0L, and it wont start. just got a new battery, new rotor and distributor, new crank sensor, sparks are working, no check engine codes after fixing these things, its cranking and there seems to be fuel pressure on the fuel rail valve. but it dosent start. and i have left the jeep out and it seems the car drained my new battery, there where no lights on and the keys where out. i've done over 1300 in repairs since i got it 8 months ago and I'd hate to see it die so soon! any suggestions?

 

also, this has been a gradual problem; it used to not start immediately sometimes, but when i hit the gas itd start up, then slowly id have to leave the car in the on position for a few minutes before it would start. for the past few months, IF it would start, id have to leave it on over an hour most days. then i got the new battery, and that didnt help it. now it does nothing
