my scan tool is reading a "P1389 manufaur control ignition system or misfire" What the hell is this. I looked in the Haynes manual and it reads "An open condition detected in the ASD relay output circuit". Please help. The truck turns over but I am not getting any fire at the coil. It is a 98 3.9 stock Dakota

 

its a bad pcm or a open asd relay output circuit
