You can do it in chassis but you will have
the trans out to do the seal. It is much easier to pull the engine at that point. The 6 cylinder is not that bad to remove.

The 6 cyl engine uses a coil strip for all 6 cylinders, and the 8 cyl uses one coil per cylinder. So I assume you have an 8 cyl engine.
You are saying one coil has power but is not firing ?
Have you switched it with another cylinder to eliminate the coil as a possible problem ?

The 6 cyl engine uses an adjustable pulley to keep the belt tight.
The 8 cyl engine uses a tensioner that is spring loaded.
You have to loosen the mounting bolts and turn the adjusting bolt to move it on the 6 cyl.
You use a bar or wrench to move the tensioner.

Have the codes cleared from the computers memory.Good Luck and have a good XMASS.From Ernie At RedDeer, Alberta Canada.

if you cant rebuild then off to the tranny shop

My moms fan switch went on her 01 gr cherokee and had the whole fan and relay replace, when is doesn't come on the fan motor is bad and won't regulate power, so the mechanic says, Please rate is thanx

go to autozone they will check codes for free

a bad cam sensor will cause vehicle to shut off while driving, and cause a hard time starting. but this usually sets a trouble code p0340. scan vehicle to see if any codes come up. after it is fixed, erase codes with a obd2 scanner. if you do not have one, you can go to any auto parts store and they will erase codes for free.

p0306 is a #6 cylinder misfire trouble code..have seen a faulty injector on 6 cyl model,plug and/or coil on v8 models
