Where are the spark plugs


Locate the spark plug wires in the Cherokee cylinder head. In the 4.0 liter engine, the spark plugs are below the coil rail assembly. On the 4.7 liter engine, the spark plugs are located under each corresponding engine coil.

You are wanting to build a "franken-jeep" and you are wanting somebody to tell you how to do it? I have 2 words for you... GOOD LUCK! You should probably try a Jeep forum someplace where they talk about doing stuff like that all the time.

1996 Jeep Cherokee Sport, 4 cyl, check engine returns obdi error code 72. Is this the catalytic converter? Car runs great, no other problems.


The code refers to the catalytic converter efficiency. It can be a plugged converter. leaking exhaust, vacuum leak, fuel pressure problem, or even low compression. You really need to have the ECU read with a scanner that will give you the POXXXX code instead of the 2 digit code. This will help diagnosis the problem much better.

Where is the crank shaft positioning sensor located on a 01' Cherekee Sport with a 4 liter? What are the symptoms of a faulty Crank shaft positioning sensor?


Look at the area around the crankshaft pulley. It's bolted to the block and senses the crank position. If it fails, You won't have an ignition spark. Good Luck, Ned

2001 jeep cherokee want start


Dont worry about wire checks at this point. If the "no bus" message went away after disconnecting the sensor, then the sensor is bad. Replace the crank sensor and all will be good in the world again.

If the data link is not talking to the computer check your ground at the computer and at the data link connector to see if the computer is even alive ground pin 3 on DLC with the key off then turn key to the run position if it flashes the check engine codes record them, if no engine light, does the engine light come on when you turn the key on then go off? if not, check fuses if not check power for pin on computer, if it has power you have a bad computer. But TEST THE GROUNDS IT IS THE BIGGEST FAILURE For these rigs or any manufacture. check that you have power also at the DLC too. if not you need a digital ohm meter and a subscription to http:///.www.alldatadiy.com and start reading the campaigns on that vechile for computer and trouble tree for dead DLC and computer. I don't have that subscription or I could tell you more where to look, if you need anymore help let me know. Also if the crank sensor could cause it not to run the fuel pump but so can the cam sensor. You need to find out if the computer gets it's pulse for the pump at the computer if it does then you need to test them both. There are three wires a ground a colored power wire and a wire to go to the computer you can test these sensors with a meter to see if there is a pulse to each. sometimes the fuel pump gets it's signal from the coil pack so it's important to have the subscription, you can do a search for each item and test them as needed and has a wiring diagram.
