So I've been having problems for awhile (Since April '10) getting my XJ to start about every 10th start. Many told me it was the CPS that was going bad and it just wasn't catching cylinder one fire. Logical enough. I changed it out today and guess what happened. Started right up. Now this was around 3:00pm today and now it won't start up with out giving a touch of fuel, then it sputters to life. I'm not sure why that helped because fuel pressure is excellent (Shot to the fender almost). My question is there any other part anyone knows of that would be faulty in this situation. If anyone knows what parts I should start with/check first I highly appreciate it.

 

it sounds like the throttle positioning sensor mine has gone out a couple times the first time it went out i had to give it a little gas for it to start. Its a easy and cheap fix to

 

That was one of my thoughts too. I know they are prone to just dying, but I wanted to see if anybody thought the same. Thanks!

 

yeah it does weird things when ever it goes out the second time mine went out it wouldnt shift until 4k lol and sometimes they wont idle when they go out to

 

does it show any codes not cel codes

 

Nothing on the OBD meter and nothing from the blink method

 

hey man.... x2 tps, but could also be iac.... always make sure your battery is strong and good to go, then start looking at other components.... good luck!

 

I'm more set on saying it's the tps. Battery is relatively new and all new wires connections etc. so I'm pretty sure tps.

 

hey..Anybody knows where the TPS location is? Pictures will help better. Thank you!

 

Having to tip in the throttle to start can indicate a bad throttle position sensor. Located on the throttle body. Not too expensive.

They don't always set a code.

 

its on the back of the throttle body it has 2 star bit screws holding it in
