i have a 1989 dodge truck with a 318 motor, the problem iam having is iam not getting voltage to my 02 sensor, i have good ground on the motor and chassic. can any body help

You need a schematic.. Check the 5 volts at the computer & trace which line feeds to the O2 sensor. Sorry I don't have a schematic

I agree with Lynn... :)

Use the "AllData" if you dont have a service manuel...
