i have a 2001 jeep cherokee that when it first starts it runs smooth..2 mins later it starts to rev up rev down might even stall, runs real rough, then sounds like a bad lifter aswell..but the tick will go away at times to..everything ive read is the crank postion sensor..which i did replace..but it was a cheap one from ebay..guessing i should prolly get one from a dealer....problem tho is where the cps plugs in to the electical connector previous owner cut that off so it has to be straight wired in..i wired it exactly how it was before..i dont no if previous owner had it correctly wired tho and i cant find a diagram..just lookin for info on wiring and also if anyone has any opinion on what else could cause it to run like this

 

Doesn't sound CPS related. Can you post a video of what is going on?

 

"straight wired in"
How?

What's the fuel pressure in psi?
Any codes?

 

p1391

 

how do u post video can only see pic..sorry new here

 

Upload to Youtube then post link

 

 

 

right now as its running its not makin the lifter sound the idle was just up and down then started runnin rough shakin and like it wanted to die

 

wherebthe 2 connectors connect underneath the jeep we had to cut the connector off the cps because the other wires didnt have the electrical connector is was just wire to wire

 

That code is for intermittent lose of the crank position sensor. You need to focus on that circuit. You said the PO deleted the connector, what type of electric connection have you made? Wire nuts, crimps etc? The ECU is intermittenly losing signal from the CPS. Check all your wiring and connections. Contact cleaner is your friend. If all else fails and circuit looks good maybe try a Mopar CPS.
