'97 XJ won't start...and no codes
Hi,
I have a 97 XJ that won't start, it turns over, but just won't fire up. Now, ordinarily, i wouldn't bother posting with something of this vague nature, however-- I can't pull up any codes. Not even a 55 will appear, so does that mean the computer brain is dead? The jeep was fine last night when I parked it, i filled up completely yesterday on gas...fuel pump? If it was something along those lines, wouldn't I still have at least a 55 appearing when i try for the codes? Any help would be appreciated, thanks Sandy phantom_milkie@yahoo.com |

On the older ones, this is a mesh strap from the rear of the engine head to the firewall. There are more computer grounds on a bolt by the dipstick.

It will not always code. (it only codes if coil opens up not usually if the sensor is weak and not triggering right. When it is bad, you will not get any fire at all. Check it before you go on a wild goose chase like suggested above. If sensor is good then go to plan "B" the goose chase but the CPS's do go bad with age and can fail suddenly. ----------------- TheSnoMan.com |
