I have a 97 with a 4.0. Had a problem a several months ago. It would take 2 crancks for it to start. New fuel pump and fuel pressure regulator and I was back in bussiness! Now start the jeep and with out the puting a little pressure on the gas pedal it will die untill it warms up. It happens when cold and after it's been running a wile. Looking for ideas in what direction to go with dumping a lot of money in to it like the last problem. Has a new crank crase senser. Any help would be great.
