If you have a 0 reading from cylinder 2 that means there is no compression from it and you need an enfine rebuild.It seems that there had been damage to the engine.Have it hooked up to a computer and check diagnostic code.Overheating of an engine can be very costly and damaging, rememeber that always.

Zero-compression or lost compression indicates that there is a fault in the integrity of the cylinder involved. In your case, #2.

Rough running after overheating is a sign of engine damage. Most often a warping of the cylinder head. This is also manifested by the lack of power and fouled plugs.

Have your engine checked by a qualified mechanic immediately to thoroughly assess the extent of the damage in your engine's internal components.

Hope this helps.

2005 Jeep Cherokee miss fire on fifth cylinder


Pull the spark plug to see if it is oil fouled, preventing firing. If it is, you may have a mechanical problem in cylinder 5- do a compression test to check for low compression in that cylinder.

If plug is clean or only showing black sooty deposits from unburned gas, the problem could be either in the secondary ignition (plug, plug wire, coil), or an injection problem. Try a known good spark plug and spark plug wire, also a known good coil, if plug and wire wasn't it. If checking for spark, you need to see a blue snapping spark when cranking engine to verify good ignition. A weak or orange spark, or intermittent spark is an ignition problem.
To check injection circuit on number 5, you can purchase an inexpensive "noid light" at parts stores. It plugs into the injector connector, and if circuit is good the noid light will be blinking when cranking the engine over. It is rare for injectors to fail, but if circuit is good and no gas is getting into the cylinder, injector may be bad or plugged.
Good luck.

Spark plugs worn,fouled or not gapped properly.Fault in the fuel or electrical systems.Faulty spark plug wires.Vacuum leaks at intake or hose connections.Uneven or low cylinder compression check compression.

2001 jeep grand cherokee limited wont start after oil change and gas fill up


was the gumout for gas or oil they look simular other than that make sure you havent fouled your plugs pull them take a good look if wet or soaked get new ones and try it also you may want to take out all your plugs and turn it over to see if your getting to much fuel You may want to change the fuel filter first just to put that out of mind its usually the simple things fuel filter makes the most sense

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.

My 2004 ford freestar with the 3.9L has been fouling out plugs with some consistency. they look to be oil fouled did compression test and they 1)195 2)200 3)200 4)205 5)200 6)205. any ideas od why they...


You need to have the rings replaced. Do the compression check again on a cold motor with this exception, add a small amount of oil to each cylinder. First do the test on the cylinder and record the pressure then add a small amount of oil and redo the test and compare the compression. I am attempting to identify if the problem is rings, valves or head gasket. I am concerned about cylinder 1. The compression is within range however the readings you provided indicate uneven compression. If after you add the oil the pressure evens out across the cylinders the problem is rings. If you get the same readings during both test the problem is the Head Gasket or a need to have a valve job done. The fouling is caused by oil getting past the rings or seals. Use regular oil in this test preferably in a hand oiler. Two to three squirts should be enough. DO NOT USE WD40 OR OTHER SPRAY LUBRICANTS. Those will damage your cylinder walls.

Oil on spark plug


The most common cause for oily spark plugs are worn rings in that cylinder or valve guides. Have compression check done on your cylinders to verify if the #6 cylinder has low compression. If compression is low only recourse is to have the engine overhauled.

Need ignition firing for 95 4 l. engine


1-5-3-6-2-4


ALL Jeep 4.0 motors use this firing order. Any year, any model, high output or not.


Also, the spark plug wire placement on the cap, in a clockwise direction from the post nearest the engine block is: 6-2-4-1-5-3. (to the left side of the number 6 post, there should be a hold down screw or strap for fastening the distributor cap to the distributor.

95 5.2 in grand cher. one cylinder low compresion even with new heads doesn"t use oil either like bad rings do


Try a leak down test, similar to a compression test, but fills the cylinder with air and regulates the amount of air escape. This may help.

Where are the spark plugs located in a 4.7 2001 grand cherokee?


On the 4.7 V8 engine, each individual spark plug is located under each ignition coil.
Prior to removing spark plug, spry compressed air around base of ignition coil at cylinder head. This well help prevent fireing material from combustion chmber.

Review your Service Manual for Jeep WJ Grand Cherokee.

Hope helped (remember rated this help) Good luck.
