My xj won't start. Its a 2000... engine and electronics are completely stock. 4x4, 4.0 lt., auto.
Here's the what happen. For the past year I've had an intermittent stumble when hot. It happened maybe once every 2 months. The engine warm. turn the key. stumble stumble stumble. You take off and its fine. No smoke, no back fire.
So today it ran fine as usual. I drove it around all day with not even 1 glitch. I come home for dinner... Shut it off. I came out 45 min later and nothing. It cranks and cranks. Now, the guages don't register, the fuel pump won't prime (I jumped out the fuel pump and it DOES work.)
So I cycled the key 3 times and (where the odometer is) it reads "no bus". I hooked a snap-on Diagnotic computer to it. And It says there's no comunication with the PCM. Its never been under water. All connections are clean.
Has anyone had this problem?
Does the PCM need to be replaced???
