Hi
i put a new distributor in my 1999 jeep tj 4.0 liter and i cant get it to fire
i have had it barely start and spudder my timing mark was lined up and i was top dead center and my rotor was on number one on the cap if you have any info it would help leaving for school on sunday thx scott
 

Did you install it per the instructions in the FSM? It should only go in one way, and it starts before the rotor is on #1 as it spins when you lower it into the block.
 
4.0L 6-Cylinder Engine: Pre-position distributor into engine while holding centerline of base slot in 1 o'clock position .Continue to engage distributor into engine. The rotor and distributor will rotate clockwise during installation. This is due to the helical cut gears on distributor and camshaft. When distributor is fully seated to engine block, the centerline of base slot should be aligned to clamp bolt mounting hole on engine .The rotor should also be pointed at 5 o'clock position.
It may be necessary to rotate rotor and distributor shaft (very slightly) to engage distributor shaft with slot in oil pump gear. The same may have to be done to engage distributor gear with camshaft gear



The distributor is correctly installed when:
  • rotor is pointed at 3 o'clock position (2.5L engine), or at 5 o'clock position (4.0L engine)
  • plastic alignment pin (or pin punch tool) is still installed to distributor.
  • number 1 cylinder piston is set at top dead center (TDC) (compression stroke)
  • centerline of slot at base of distributor is aligned to centerline of distributor holddown bolt hole on engine. In this position, the holddown bolt should easily pass through slot and into engine.
No adjustments are necessary. Proceed to next step.
  1. Install distributor holddown clamp and bolt. Tighten bolt to 23 N·m (17 ft. lbs.) torque.
  2. Remove pin punch tool from distributor. Or, if plastic alignment pin was used, remove it straight down from bottom of distributor. Discard plastic pin.
  3. If removed, install camshaft position sensor to distributor. Align wiring harness grommet to notch in distributor housing.
  4. Install rotor [SIZE=+1]CAUTION: If the distributor cap is incorrectly positioned on distributor housing, cap or rotor may be damaged when engine is started. [/SIZE]
  5. Install distributor cap. Tighten distributor cap holddown screws to 3 N·m (26 in. lbs.) torque.
  6. If removed, install spark plug cables to distributor cap. For proper firing order, refer to Specifications section at the end of this group. See Engine Firing Order.
  7. Connect distributor wiring harness to main engine harness.
  8. Connect battery cable to battery.
