Hey there I have a question pretty new to the idi world. I have a 1989 7.3 with an aftermarket turbo hooked up to a factory c6 3speed trans. My tach isn’t working and I’m trying to figure out where I should start. I am 99 percent sure the in cab tach is stock but my truck having the c6 it doesn’t have the tach sensor strapped to the IP. Everywhere I look everything refers to the tach sensor for the e40d on the injection pump but my truck doesn’t have that having the c6. Any clues on where I can start? Sometimes on start up it’ll jiggle a little up to 800 or 1000 rpm but never reads over that and once I start driving just sits dead at 0. Thanks for any input in advance!
