Hi I'm new to the
Form so what I got going on is I have an 01 xj that we picked up with an 87 xj the body was trashed we had plenty of parts to rebuild body we were under the impression that the key had to. Be programmed but turns out the 01 didn't come with that option the guy we picked it up from gave us the original tumbler we installed that no change still starts every time but dies with in the ten sec we have good fuel presser new plugs no vacuum leaks that we can find I'm still thinking its a key prob but at this point I've done just about everything but shoot it with my gun any ideas would be great thank

 

"still starts every time but dies with in the ten sec"

So what goes away fuel or spark? Have you done a compression test? Any codes?

 

It's not the fuel never looses psi tryed to check spark but the coils and wires. All one piece it will stay running on starting fluid thow

 

Ive not done a compression test yet code is a p1686 witch is no skim MSG received

 

"will stay running on starting fluid thow"

Check the fuel pressure with a gauge @ the schrader valve.

ETA: Scratch that ^^^^^^^^^^^^^^

Whole different story, has the key been programmed to the vehicle?

 

46 psi all day

 

The dealer ship said that this one don't have that someone put a dif steering column in that did require it but we have put the original back in and It's tagged no for Elc key

 

Does the PCM reflect the correct VIN for the vehicle?

 

The computer ? Idk I'll have to check

 

Ya the computer needs flashed

 

How do you flash the computer?
