The assembly line data link won't give me any information when I plug in the obd1 it only informs me that no information is available from the ecm (computer). The service engine light is on and I can't scan the engine to detect where the fault lies. Also my transmission is electronically controlled and stays in second gear without shifting into drive. I just installed a new computer with no change in the system. How can I scan the engine or get power to the scanner plug under the dash. If a bad ground is the problem can I run a new ground wire to the computer and if so which of the terminals are the ground terminals. Are there schematics available that outline the wiring diagram of the plugs?
have the same problem?
