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

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

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

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