Need help on a starting problem

[RitchieDon]

After battling this problem all winter long, my mechanic finally found the problem. The plug that goes into the Engine Control Box on the passenger side is bad. When the ignition fails, you can push down on the plug & everything lights up. Problem is when you release the pressure, everything shuts back down. He tried to fix the connection but it can't be repaired. I'm going to have to replace the control box. He has checked with all of his sources and can't find one so he called the local dealer and they haven't come up with one either, yet. If anyone has one or knows where I can get one, please let me know. There are 5 different sets of numbers on the box and my mechanic told me that of the 5, you never know which one the people he has talked to will want to identify the part so here they are:

8093755992
09375599
3.5L AUTCAL
SN# 09376671
8255995083648340

He also said the part may be a little pricey so I'm looking for the best deal I can find.

Thanks Maugan but I was really hoping someone out there with a parts car could help me out without having to pay for a new unit. My mechanic tells me that this is a part that rarely fails. Mine is probably bad because the previous owner had a roll-over which most likely put a strain on the wiring harness and caused a weak connection in the control box. The part I'm looking for is located in the compartment in front of the shifter and below the CD changer. I really need some help here. The people at work are riding me pretty hard because I have a "fair weather vehicle". I know the VX can blow all of them away but it's no good if I can't start the thing.

Glad you isolated the problem area.
Looking for someone with a parts car is like...well, like a needle in a whole barn full of haystacks.
Your best bet is to locate a salvage yard in California or...a (shutter) dealer.
Good luck.....John

Latest update on this ongoing problem. Hotsauce helped me out with a new ECM (Thanks again, Hotsauce) but unfortunately, that turned out to be not the problem. After installing it, I'm still having the same problem. The weather is now warming up here & I probably won't be able to resolve this until next Fall. I have reset the wires going into the plug but it failed to start again early this week. I am still suspicious of the ABS light that comes on. I hear it "ping", then it goes off momentarily & then "pings" again & stays on. The sound is coming from somewhere behind the glove box. Problem is, when the temperature warms up past 35 degrees, everything works perfectly. This is going to drive me nuts all Summer & is going to get real expensive replacing parts like ECM's, etc.

During the cold weather, Try removing the 40 amp ABS fuse & see if it will start. Do due to the large amount of current draw by ABS (Normal) & reduced battery capacity in colder weather a problem may exist in the ABS circuit resulting in excessive current draw.
