1999 Sport 4.0, Auto trans.
New Crank Position Sensor (Mopar).
New Plugs/wires/distributor cap/rotor/coil.
Made the mistake of setting TDC to the exhaust stroke on cyl #1 when I pulled the distributor to drill out the broken cap screw. So I did get a crank/no start from that. On the advice of someone on another board, I swapped the ignition wires 180 degrees (1 over to 6, etc.)...and it started fine twice. Daughter drove it the next day...started fine, drove great (the hesitation from 4 to 3 shifting was gone...still not sure why).
Then yesterday morning...she calls and says it won't start...crank/no start. She tried it twice...then took another car.
After working on another car (I got home after 7pm...got to the Cherokee around 8:30pm), I decide to check it out. Pop the hood...make sure the coil wire was fine (it was). Crank it...no start. Turn the key (buckled belt, lights off, door shut) so I can hear the fuel pump run on turning the key...it did twice. Check the schrader valve on the fuel rail to ensure it's getting pressure...I get a spurt.
Try one more time...catches...then it acts like it wants to die (drops to around 500rpms before I push on the gas...hold it at 2k RPMS for a few minutes (call my Daughter to come move the other car so I can move the Cherokee up near the garage to work on it)...let off the gas, it's idling fine.
She says 'there's a 1/4 tank of gas in there' (but it's pretty damn close to 1/8th tank)...can low fuel cause an issue like that?
If the check valve is weak/not working...how long does it take to get the gas back to the engine?
Thanks for any ideas!
