and yes i checked both fuse box. I didnt see any fuses blown.

 

Not to disregard a possible moisture problem, try something simple. Disconnect both battery cables and make sure contacts and screw are clean. Reconnect, positive first, negative second, making sure they are seated properly and securely. Changed battery in mine and it worked for awhile then did what you are talking about. It was the connections.

 

Do as suggested, check the battery cables and while you're at it, check the voltage across the battery. I want you to send a PM to Bill Curlee as he's the expert here on the electrical things. If it becomes necessary to open the BCM to remove the moisture from inside of it, here's what you need to do. First, disconnect the battery. Extract the BCM. Now, the next part is important. You need to be electrically grounded to make sure there is no static electricity on you at all. To do this, normally a grounding wrist strap is needed. Place the BCM on a grounded surface...again, make sure its electrically grounded. Open the BCM. Use Iso Alcohol with a q-tip or light brush and clean the entire board, front and back. Do this carefully and completely. If necessary, use some electronic parts cleaner (spray) and hose down the entire assembly. Wait...let it dry thoroughly and inspect for any leftover comtaminates. Clean again as needed. Again, make sure you and it are electrically grounded as static electricity will damage it. Put it together again and and install it into the car, reconnect the battery. If things don't work, you'll need a new one and a trip to the dealer to program it. If you buy a new one, a you'll have to go through a relearn procedure which will get the security to the point it'll allow the car to start, but you'll still need a Tech 2 to program in the RPO codes. Hopefully just cleaning it will take care of business for you, if this is what's causing the problems. Bill Curlee will most likely have some other thoughts to try before going this far, so please send him a PM

 

Disconnect the BATTERY and remobe the BCM (The BIG SILVER BOX) Once its out, place it somewhere that nice and warm. I put mine on top of the living room lamp It will take 5-6 hours to completly dry out. You can rush it with a hair drier but dont get it too hot.

While its out and drying,,,take your battery to AUTOZONE and have it tested. Charge it! Clean your battery terminals with a wire brush and some brakeparts cleaner.

The water is flooding in because the HVAC Air box is full of condenation. Its NOT draining cause the drain is clogged! The drain is on the passengers side fire wall directly aft of the passengers head.

It looks like this:





It accessable from the bottom but can be seen from the top;







If you dont see water/condensation pour out of the fitting when you pull off the rubber boot,,,the drain tube is cloged:

its gona storm for a few days so im gona have to hold up on my car

 

Understood. I'm still here monitoring but will back out while Bill helps you on this issue. If I think of anything while you and he are troubleshooting, I'll chime in.

 

ok i did all that. Dry out the BCM box and unclog the AC dispenser and my car still wont start. Last night I wanted to drive my car so bad. So I jacked up the car and jump start the starter with a screwdriver. And it started up fine. Engine sounded great, The sound of my borlas was still awesomely loud. So i took it for a ride to the next town. And she drove perfect. But when i got home I shut her off and try to start her up and it was back to phase 1 all over again. Dad said he put a meter on the wires that connects to the starter and one of the power wires was not getting any power. (Not sure which one)

 

Is the security light on the dash flashing when you attempt to start it?

 

Have we completly ruled out the battery? I know you said is was new but I've seen new batteries go bad. Was it tested under load?
Just trying to eliminate the easy stuff first.

 

If that security light wasn't flashing, I'm starting to think your TDR relay went bad. Adding to this post of mine: The TDR relay which is right close to the BCM is what sends the signal to the starter solenoid to turn on, therefore engaging the solenoid which in turn, connects power from the battery to the starter motor. The very, very interesting part in this saga is that you jumped the battery to the starter motor and the engine not only started, but it ran, it drove and so on. This is possibly very good news of course. What you should probably do is look through Bill Curlee's posted pictures in the sticky of the Tech section till you find the TDR relay. He points to a couple of wires going to it that you can short and the starter solenoid will engage. One of them is purple but I don't remember the other color. Whatever you do, make sure the car is in neutral when you do this because it will start up and drive away without you. If it starts, shut it back down. Locate the wiring diagram for this relay and put a meter across the coil contacts of the TDR relay and determine if you are getting the 12 vdc start signal to this relay? If you are but the relay isn't closing the contacts or if it is, but not sending the signal to the solenoid, then your TDR is bad. If the TDR is not receiving the 12vdc at the coil contacts then we go back to the security systems.

 

it was the anti theft relay that went bad.

 

Great news glad your back up and running. Remember to keep the udders and A/c drain clear, also each fall I do the radiator to make sure no leaves are clogging it. Now take it for a spin!!!!!
