Thank You, horseydug. I think its starting to make sense to me now. So tomorrow I'll re-check the draw and be sure the doors are closed.




This is getting stranger by the day: This morning I went out and measured the current drain. With the Courtesy Lamp relay pulled, the Courtesy Lamp fuse pulled, the Luggage Compartment Lamp pulled, and all doors closed, it measured 3.6 milliAmps. Kewl!

Open the door and the milliAmps jumps up to 16.4 milliAmps (Don't know what that indicates since the Courtesy Lamp fuse was pulled, but the electronics musta initiated something.)

With it reading 16.4 milliAmps, I closed the door, and the current drain drops immediately to 11.7 milliAmps. (I'm assuming the CTM is doing something.) Then about 30 seconds later, the current drain drops to 3.6 milliAmps. (Again, I'm assuming the CTM finished whatever it was doing.)

Then I installed the Luggage Compartment Lamp and repeat the process, and get the exact same readings. So far, so good!

Now comes the kicker - I install the Courtesy Lamp Relay, crawl out from under the dash and check the DVOM at the battery. Its now 0.0 milliAmps! Close the door = 0.0 milliAmps! Open the door = 0.0 milliAmps! Yesterday it was reading 155 milliAmps. Must be I 'fixed' the sumpin!

So I hook the battery cables back up, ground the STI, and try and pull the PCM codes. I can hear the solenoids and engine fan doing their dance during KOEO, but the check engine light doesn't flash, not even the '111' pass code. I've pulled the PCM and done the Pin-point tests to check out the wiring harnes for VREF, STO, STI, etc. All meets the pin-point test specs. (At this point the shop manual calls for a new PCM, but I've been told someone has already put another one in.)

So I say, what the heck - I unground the STI, turn the key to on (CEL lights!), crank and crank, (CEL goes out, meaning it see a PIP signal!), and it fires a few cylinders, but not enough to override the starter. So I disconnect the MAF, crank and crank some more, and it starts!!! This is first time I've heard this engine run! (Its been flatbedded to two different Independant repair shops and a highly regarded Ford dealership in the area, before it was flatbedded to my place for one last attempt to save it from the crusher. )

It doesn't sound pretty in there - reminds me of an old Ford diesel tractor when it idles - maybe I should start another thread for that problem.

Then, just for S&Gs, I shut it down (the noise was deafining), ground the STI, and run KOEO again. Solenoids and fans do their thing, and the CEL starts flashing!
I get the 111's folowed by 157, which is a MAF code. Why is KOEO working now! Does the engine have to be at operating temp for the PCM to code the KOEO?

Sounds like I fixed the electrical problems Now on to the mechanical noises!
