Vacuum you are seeing is about 13inches low. either something is causing the timing to stay retarded or the timing chain is stretched beyond it's limit. Id check the MAP and throttle position sensors as they have influence over timing (and fuel mixture) and check the chain for stretch. Since you had the distributor out, it is also possible that you have installed it one tooth off...that also can ****** the timing.

The firing order is correct on my 97 jeep cherokee sport 4x4 6.0 and it still will not start, why not?


I looked at info for 4.0L engine. I don't know what testing you have done?
make sure battery has a full charge, if it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure, also, check fuel injector pulse. If your missing all three, check cam and crank sensor. Don't replace anything unless your testing points in that direction.
Any applicable trouble codes? What about security system?

My jeep cherokee sport will not start what do I check first?


In a 96 Jeep not many sensors are involved. Basically Fuel and spark delivery at right time should start car if your Starter is able to crank the Engine.
If engine is cranking then the battery is Okay. Check Spark directly at the spark plugs and fuel pressure at the fuel rail. You may pull out one spark plug and check spark out of engine.
Try spraying Starting fluid in Air Intake while cranking. If Jeep starts then not enough fuel is being delivered by fuel pump. If you find no spark at plugs then check circuit for starter relay, Crank sensor/cam sensor problems.
A kill switch or bad Alarm system can also cause this problem.

I have a 1996 cherokee sport. It does not idle when cold. I replaced the air control valve, but no improvement. whats the next step.


If your check engine light illuminates when the jeep is running bad, have the trouble codes read to find out what exactly is the problem. I would guess and say it's the heating element, of the O2 sensor, that is bad and causing hard starts when cold.
