Hello, does the check engine light come on in the dash when the key is turned to on? The eec power relay sends power to the pcm and turns the check engine light on in th key onposition to verify the pcm is being energized.When you are jumping the starter relay is the key on so the pcm can start the engine? Is the red theft lamp blinking fast when the key is turned to on?
Yes, that is the light for the engine that should come one when the key is turned to on since you are having an issue with pcm communication and pin 16 on the data link connector should have power for the scan tool. lower right corner last pin terminal
With the key out of the ignition the light will blink on/of.when the key is turned to on it should stay on steady for a few seconds and go off.if its blinking with the key in the on position it has a PATS antitheft issue, but it wont cause the car to stall.
Ok. so the service engine soon light comes on when the key is turned to on? Does the theft lamp work as it should and you have no communcation to the pcm with a scantool?
Ok, most likely you have a failed instrument cluster which is the module for the PATS system. You can try banging on the dash and see if the odometer display works or not. The Cluster is a programmable module and when replacing must be reprogrammed to the truck and you will need 2 ignition keys to reprogram to the instrument cluster. A local locksmith may be able to do the job for you on your site. if not it will have to go to a dealer to do the instrument cluster repair and repgoram 2 keys, if you have one key you must have two to program the truck to start
The instrument cluster itself is the module, the whole cluster would need replacment. You have to have two keys to reprogram the pats system, the cluster is called the HEC module for the PATS system. Check with your local locksmith if they can program pats keys and insturment clusters.
