Hello, I have a 1986 Jeep Comanche, 4 cylinder 4x4 5 speed that i just bought used. The battery is brand new, same with cap rotor wires and the alternator i just bought. the jeep kept draining the battery and it would basically shutdown completly. i put the new alternator on thinking it wasnt charging the battery, but it continued to drain slowly then completely die. im thinking the next option is to replace the voltage regulator. any help would be greatly appreciated.

Check the spring tension on the advance weights in the distributor. May be weak or the pivots may be sticking. Best way to test is with a timing light. See if the timing advances and returns correctly

buy a repair manual at auto parts store... it will tell you what you need to know... like how and where to adjustment bolt is...

The factory aluminum wheels on Jeeps tend to become fused to the rotor and drum surfaces. A lot of can spray rust remover and a lot of tire kicking, after removing all the lug nuts, that will loosen up the bond between the wheel and rotor surface and the wheels will start to come off eventually, lots of kicking, alternating between the top and bottom of the tire.

check your plug wires there could be faulty then if not come back to me

You have spark on the coil wire but not coming from the cap. You replaced the cap right. Did you replace the rotor too. Sometimes the rotor burn in the center and the spark goes right thru it in to the distributor shaft.

I sincerely apologize for the late response...Due to the bad economic situation this site has had a substantial (+50%) increase in the number of questions being asked in the last four months.

I am not sure if you have the 2.5L or 4.0L. However I have included both below.

For the 2.5L (4-cylinders):
Firing Order:
1-3-4-2
Cylinders:

Distributor:

For the 4.0L (6-cylinders):

Hello Macstff ;

1985 jaguar xj6 4.2 L Series 3
Firing Order 1-5-3-6-2-4
# 1 Spark plug at the last cylinder next to the firewall .
# 6 Spark plug at the front of th Engine nearest the fan .

The Rotation of the Rotor within the distributor cap is " Counter Clockwise

The Vacuun Advance Diaghram ( metal ) is more in line with the # 3 Spark plug wire .

Looking from the top near the Passenger side fender . If we know that the Number 3 Plug is more inline with the vacuum advance then moving " clockwise the next plug would be the # 5 and after that would be the # 1 plug

This shold get you on your way providing that nothing else has been tampered with . I hope that this has been helpful to you .

if its a 2.8 the firing order is 1-2-3-4-5-6 and the distributor rotates:clockwise if you lose this look ontop of your intake manifold and it has it stamped on it by the number to intake.

6 cly firing order is 1-5-3-6-2-4
8 Cyl firing order is 1-8-4-3-6-5-7-2
4 cly firing order is 1-3-2-4
