Model year. Whatever the title says.

 

Did you replace the CPS with a dealer unit? Sounds like your initial problem is with the IAC but I'm guessing you installed a cheap CPS

 

Alright so when my xj is off and on a slight incline is leaks gas. I thought it was the hose but its not. The steel line that goes into the fuel pump can be moved back and forth so its leaking from there. Can I just rtv it and call it a day?

 

Hello, im new in this forum and im portuguese so sorry for some bad language...i have a cherokee classic and at some time that i have a problem wish i know becames from " fuel arriving in the engine " case the jeep doesnt respond when i acellerate it , or yes respond in begining but after i accelarete a little he doesnt gett the velocity he should, now i dont know if it will be the principal injector or the fuel pump or even something in fuel deposit , but becase i toke off deposit at short time ago i dont think so. Someone can help me how can i have sure about this problem , testing the injectors wish i dont know how or testing the pump wish i dont know too? thank you all guys

 

Start by checking your fuel pressure off the fuel rail.

I can't remember what its supposed to be. Someone else might chime in on that.

 

Short version: Jeep isn't accelerating properly. He wants to know how to check fuel pump and injectors.

Joaopaulo, what year is your Jeep, 1984-'01?

 

my jeep is from 2000..and he accelarete right , the problem is he doesnt respond at some point , like my jeep can go to about 160..170 km velocity.......now he goes only about 120km, there is something not woarking that doesnt let the right fuel in the engine.
About the fuel presuure i never heard about where is that or where can i see that

 

You need a fuel pressure gauge, and you hook it to the fitting on the fuel rail.

 

ah ok , so you mean i do that really in the fuel deposit of the jeep right? im not sure i undestand what is the fuel rali you said here

 

Ok im sorry, i think i undestand now, i need to gett a fuel pressure tool and do it near where is the injectors...i just dont know how to do that but thats a begining..thank you

 

Do yourself a favor and get a hanes Manuel.

 

hey guys i have a 99 sport w/4.0 and its somewhat new to me. I started to get a ticking from the cap and rotor, took it apart and the connections were pretty corroded and worn so i decided to do plugs wires cap and rotor. I went with accel found the tune up kit pn:tst16 copper tip plugs, brass connections on cap, 8mm wires runs great but when it warms up im still getting a light ticking from the cap and rotor, could it be the coil since i didnt change it all advice appreciated. is this an issue or normal for these 4.0s

 

Are you sure its the cap/rotor area?

 

when i put my hand there while its running i can feel it there and nowhere else even with an extension to my ear its the only palce i can pick up the ticking

 

Any known running issues?
