What's the temp gauge reading, and did you check to see that the coolant was at the proper level? Let me know. After you run then cool then run a bunch of times and when you know the level is good, and the engine light is not off, pull the negative terminal on the battery for 2 min< turn the key on, turn the key off. Replace ground and fire it up. Let me know what happens.
