Maybe double-check your ignition wiring? You are turning key off but the curciut isn't being broken.Find a wiring diagram and check and see if you have any wires crossed to solenoid. Good luck :D

Suggested Repair

Recheck the ignition wiring so the circuit opens when the key is turned off. Compare the connections with a wiring diagram and look for wires crossed at the starter solenoid.

Conversation Summary

A 1995 GMC C1500 4x4 with a newly installed engine starts and runs, but it will not shut off when the ignition is turned off, and the dash lights stay on as soon as the battery is connected. Pulling the coil wire stops the engine. Replacing the starter solenoid did not help. The expert advised checking the ignition wiring and comparing it with a diagram for wires crossed to the solenoid, since the circuit is not opening with the key off.
