I have an 88 chevy 1500 with the 350 tbi. I have the problem with the coil not sparking. I have replaced the coil and rotor button and still no spark. I read on here that it could be the pick up coil or the ignition control module, but it said I wouldn't be getting fuel to the TBI if it where either of those. I am getting fuel into the TBI. Just no spark at all. What do I need to look at here?
How long since a tune-up? Any applicable mil codes? Did you check for primary voltage at the coil, pink wire, goes hot when you turn on the key. What about the coil wire and distributor cap? I forgot to look for esc module?
