I have a check engine light on.

Thanks, I am trying that now... I'll let you know how it turned out. OK, I pulled the battery for 30 min., reconnected and the light is still on. What would I look for electrically at the plug to tell if it's that, A voltage or a resistance between a pin and ground?

you need to check for 12 volts at one plug with the key on and the return is the pcm. you need a shop with a scan tool that can turn the solenoid on and off to verify the pcm commands. Roy
