Working on a '00 WJ (Grand Cherokee) that has suddenly lost spark. Has always ran real well but has been sitting a few months with a dead battery. Installed a fresh battery today and the Jeep endlessly cranks but won't fire. I can smell fuel after trying to start it, can hear the pump cycling. Also gave it a quick hit of starting fluid direct into the throttle body and nothing. Not throwing any codes.
Does this sound like the typical 4.0 CPS failure?

No, that sounds like the anti theft device. Try sticking the door key in the passenger door lock, then locking and unlocking the door three times in a row. Then try the key in the ignition.
I had to edit because I hate auto correct!

I'll give that a shot. I think this is one of those "genius" models with only one key hole in the driver's door and none on the other side. Should then work with the driver side door, right?
I don't think there's anybody that likes auto correct. :p

Just watched a video on YouTube about the same issue on the same Jeep. I think you nailed it Redone! The check gauges light and anti theft light are lit up when trying to start it.

It should work in the driver's door, but that switch wears out first, which is why I recommended the passenger side. If the other side doesn't have a key hole though...I doubt drilling one yourself will work.

Let us know if it works! I spent the better part of an hour finding that tidbit for resetting the anti theft after thieves broke into my GC. It'd be awfully rewarding if the same knowledge paid off twice.

Tried the key turn trick and got an acknowledgement from the dome lights when I did it. Battery was low and I ran it out while cranking. Will have to try again this weekend.

Did the lock/unlock trick and I was able to get it running. I haven't run it in about six months and it is CRANKY! Once revved to over 4000 rpms it smooths out and runs normal but anything below that it runs pretty rough.
