glow plug relay not working truck is blowing smoke beyond your wildest imagination now the weather is cold or hot outside on day one and my truck now has codes for one of the fuel injectors shorted injector wires shorted under the valve cover and my Truck ran on a bank. Not to mention my driver's side gasket was leaking so much oil I thought it was a hole in my valve cover! Please don't do the job twice like I had to use motorcycle parts and get the job right the first time
