Well, I had the no spark issue and I changed out the ignition control module, which fixed it, now it's acting up again. I changed out the pickup coil and ran the codes. Seems to run better with the pickup coil replaced, but I need help with the codes. It's a 4.9L 5 speed BTW.

211 - PIP Circuit
212 - Loss IDM to PCM or Spout circuit ground
327 - EVP Or DPFE Voltage Low
542 - Fuel Pump Secondary circuit - PCM to ground.

Any ideas on what these are and where I should start looking? The book was kinda vague.

 

Anyone? Can't figure this out.

 

Come on, surely someone knows, this check engine light is driving me nuts. It hasn't died on me since changing out the pickup coil, but I do have a random miss, usually occurring in 5th gear around 45MPH.

 

You did not mention if you disconnected the battery for a little while, then re-connect it. This might help to reset the CEL. Might be this simple if you say the trouble of no spark is o.k. now.....Ernie

 

^ good point, we all have to remember, after a repair is make, codes have to be erased, they don't go away automatically. The computor has to be cleared.

 

Done that, the battery gets disconnected any time I work on a car. The codes remain. Oh and the check engine light flashes.
