Thanks Archon! That does not match with the pin diagram I have, and actually looks more like what my PCM pins match up to....busy all morning, but this afternoon/evening, i'll be taking a more in depth look at it.

Happy St. Patty's Day!
Was a hectic week, but I finally got around to testing more voltage today. Everything in above posts was still holding the same. Replaced the TPS, still same on 5V wire.
Testing every pin on PCM for every 5V source, I couldn't get any of them to read above 2.5 V....all grounds ...

short video of trying to get a read on TPS...

for the record: I am trying to track down some place that can look at the car, without overcharging me....
(last place said $99.95, just to hook up their OBD reader, and diagnose...not even repair anything)
Funds are getting low, trying to conserve for parts vs. labor if possible

Just bought the ...

also, why do you think I cannot get to 5V on anything?

ok, so hoping i'm posting this so anyone can follow along...

tested the following, with engine in "ON" position, and grounded to the vehicle, and here's what I got:

Connected Disconnected
EGR: 3.83V 3.82V
MAF: 3.83V 3.83V
MAP: 35.64V (yes this is right!) 3.87V
TPS Wouldn't stop bouncing 3.81V
IAC ...

had moved over to a different post...turns out I had a really bad battery...all replaced now, but car spent 5 days dead with driver window stuck down (before I realized I just needed the battery). Also, had a TON of rain over the weekend, and my list with all voltage readings I'd gotten from ...

on a side note...i do have a brand new battery, with a new 3 year warranty on it...and i also have very nice, very clean grounds all around my car, as well as a cleaned up starter...

pulled starter...was dirty. cleaned it up, had it tested, starter was good.
got curious and took battery somewhere else to get tested again...3 dead cells...thankfully, it was still under warranty, so got it replaced....
now i'm just back to my original issue of a P1635 code....grrrr!!!!

Still looking into things on the car, BUT, I found out some rather disturbing news...

Apparently, my friend who repaired wires to the PCM did NOT disconnect the battery? I don't know why he would forget something as basic as that?

So, he spliced and soldered 5 wires, covered them with heat ...

OMG thank you! See? I knew there was a very simple solution that my overworked mind was overlooking...I'd been using my locking pliers on other things, and I think that's why I couldn't see the bigger picture!

Working on my car, and we have upwards of 30 mph wind gusts in the area, and my hood keeps blowing shut...a few times, closing on top of me...lol

Car will not start at all, so moving it to a less windy area out of the gusts is not an option.

Any suggestions on better securing the hood open?

(I'm ...

Today's adventure? Reconnected battery, just to see...small spark when connecting neg..nothing coming from the starter, still no lights or any other accessories...no fan kicking on...I hear a short "buzz" type sound that lasts less than a second coming from somewhere near the battery when i try to ...

very small spark when i connect the battery. no wires smoking anywhere...have checked all fuses, and double, and triple checked, and none are blown. have checked relays, and i cannot get anything from any relay at all...testlight, and nothing, no vibration from any relay, no warmth, no buzz...yet if ...

the grounding strap and surrounding areas were a bit dirty...cleaned them up, pulled out the battery and cleaned under there as well...

the battery itself is testing ok....by ok, i mean, when i had it tested yesterday, it was staying between 12.2 and 12.8
today, i noticed it's down to 11.6, and ...

problem has turned into stuff other than 1635 code issue, so I moved over to electric forum to scout out suggestions there

on an added note: I'm all static now as well! Shocking most everything I touch! It's rather annoying

Will try to keep this on topic as best i can...

here's my first post with background info on how this all started..
http://www.pontiacbonnevilleclub.com/forum/2000-2005-other-than-gxp/topic37744.html

Now, if you didn't read to catch up...brief breakdown and onto "current" issue...

Several wires ...

Doing some more thorough checking, here's what' i've discovered...

TPS stays high (min of 7V) on 5V while connected, and no voltage at all when disconnected....swapped out TPS with a new one, and same thing...5V ground wire to PCM is one of the wires that was shredded by the previous owners ...

Re-checking things today....
5 volt wire on TPS is flying all over the place...can't get a steady voltage
MAP sensor is staying a constant 4V
EGR is staying between 7.0 and 7.4V
most other sensors are staying between 4.6 and 5.2V

Also, oil pressure gauge on dash is staying low...sometimes causing ...
