Question about 1992 Jeep Wrangler

1 Answer

Changed the dist. cap and rotor, now it won't start.

I replaced the distributor cap and rotor on my 1990 jeep cherokee 4.0 and now it won't start. I put the old parts back on and it still wouldn't start. There is spark at the plugs and fuel at the rail. The ignition coil checked out good. I used a Haynes manual to make sure the wires, cap, and rotor were all put on correctly. What could it be?

Need a wiring diagram for spark plugs for a 1995 jeep Cherokee sport


V6 engine: firing order: 1 2 3 4 5 6, distributor rotates clockwise. Left bank of engine (driver's side), cylinders 2, 4, 6 (#2 at front of engine). Right bank: 1, 3, 5 (#1 at front of engine).
Inline 6 engine: firing order is 1-5-3-6-2-4. Distributor rotates clockwise.
The number one tower on the dist. cap should have a mark or numeral 1 on it. If not, turn crankshaft to top dead center of compression stroke on number one cylinder, the 0 degrees or "T" mark on the crank pulley pointer. If you are on the compression stroke (not the exhaust stroke), the rotor under the dist. cap will be pointing to the number one cylinder spark plug wire tower.

if that distributor has ever been out, it may not line up on #1. check to make sure the coil wire is connected tight on both the coil and the cap.

1996 Jeep Grand Cherokee 4.0 4 wd - changed wires, distributor cap and rotor - now it will not start? Did verify the firing and that all were plugged in correctly.


If the wires are in the correct order, also make sure that you used the correct starting point, otherwise the base timing can be off by as much as 60 degrees. Turn the engine till the crank damper timing mark is pointing to 0 or tdc on the timing scale. If the rotor is pointing towards the engine, turn one more time. #1 is roughly when the rotor is pointing towards the passenger headlamp. Order is in the direction the rotor turns when cranking. If the engine was running with no problems before the change, only other thing could be that you inadvertently unplugged something or the security system armed. Other possibility is that if you did the change due to a running problem, whatever was causing that finally failed.
If when you remove the cap again you find that the rotor is damaged, check the dist shaft for side play.
Are you getting spark?
