Engine turns over but does not start / have no communication between scan tool and DLC / also have no spark or fuel when cranking / all dash lights come on with ignition switch except engine light. Checked relay and fuse both OK. Checked power and ground to DLC OK. Checked purple data wire for opens or shorts. Data link wire to radio has been disconected due to aftermarket radio. Any sugestions, Dan
