You can check for spark escaping the system by running the engine while it is dark and looking for arcing, that is a primitive but effective way of checking. Also many times because the terminal that connects to the spark plug is in a sheath it is easy to have the sheath over the plug but not the terminal, make sure all the wire terminals are snapped onto the plugs and coil

You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.

Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)

SOURCE: 99 grand cherokee laredo wont start but turns over

my jeep did the same thing. when you open the hood, on the right hand side of the engine, it was two small rubber hoses, the back hose came off, i think it was the air intake. it was only easy to fix, just push it back on, it should be a small clamp on it.

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.

What would be my problem when my jeep is skipping really bad, i changed the plugs already and had a engine check done on it, wold it be the coils? and how would i fine out which one?


It could be bad coils. That can be checked by running the vehicle with one of the spark plugs unplugged at a time. Shut it off before trying to remove the plug or you may get a nasty shock from any working coil. Good luck!

1999 jeep cherokee 6 cylinder engine light


1.Plugs
2. Vacuum leak
3. Injector fault
4. High or low fuel pressure.
Thats the list of things to check.
This is a #3 cylinder misfire.
There is also TSB about #3 injector needing added heat protection. This could definitely be the cause. I start at plugs and go from there.
Hope this helps.
Thank you,
Lee
