Hello again so now my cherokee is doing new evil things. For starters it's been running a lil rough and some times after start up it will fire hit about a grand on the tach then sputter and die. It won't start for about 15-20 minutes after that. I just did a tune up (plugs,wires,cap,rotor,coil and filters) and it still does it. It is however running a little smoother. Help I'm stuck at the store and my boss is wondering where I am

Make sure that you have the proper fuel pressure at the fuel rail. For your year you should have 39psi at the rail. Also make sure that you have a good blue spark.

Yep^^. And when you want to spend some quality time familiarizing yourself with the Renix Jeep and reducing potential failures in the future, click on the pink link in my signature and do what's suggested in posts 1, 3, and 4.

Thanks for the help guys. I was showing 31 psi at rail so I replaced fuel pump, fuel pressure regulator, all my relays (just for ****s sake) now I have 39 psi at rail went with all factory parts cost a lil more but heard horror stories bout aftermarket cheaper parts
