87 chev fuel injected timing issue

[c10 custom]

Hi everybody i am having an issue with a 1987 chev truck 305 fuel injected
the wire that you have to unplug for the timing does not have power on it
and when you set the timing on the distributor to 0 degrees and then plug the wire in it doesnt do anything what i did was take a test light hooked to the positive battery terminal and touched the bare wire of the unplugged timing wire while the engine was running and the engine stalled out im not sure what to do any help would br great thank you everyone
