Hi Everyone, My 2004 Jeep grand Cherokee in-line 6 died while on the freeway. Got it home plugged in the scanner and got a linking error. Started disconnecting sensors and still got a linking error. In addition to this my gas gage will not move and my check engine light takes about 30 seconds to come on. Changed my CPS still no start. I also checked for spark during cranking no spark. Anyone have some Ideas on how to get the engine started.

 

Check your fuses. I dont know the Grand, but thats where i would start. Fuses. Here is a link to the Grand Cherokee tech forums. You might find more of what you are looking for there, but we are all happy to help.

Moved to Grand Cherokee Tech. Fuse suggestion is a good one. On the 1997-2001 Cherokees the Chrysler CCD bus is integrated into modules like the remote keyless entry. If that's been acting up you might start there

 

Hi , I have checked all the fuses under the dash and in the PDC. All of them are good. I have also swapped the relays with no change.

 

IDK if this helps, but the ignition has to be on to Start or the link will not work. That is, when the chime and warning lights come on.

 

Yep, plugged the scanner in then turned on the ignition. I even went so far as disconnecting the fuel pump to see if I could get the scanner to work.
