When I try to start my 95 yj it cranks but won't turn over right away. If I just turn the key to the "on" possition & wait I will eventually hear the relays click & then the jeep starts. Some times this can take up to 7 or 8 minutes depending on how long the jeep has sat. I've replaced; fuel filter, distributor, rotor, fuel pressure regulator (seems to have gotten worse since then). I hate to pay $300 for a new computor & that not be the problem, like wise I don't want to replace fuel pump & that not be it. Any indeas???
