Car wont start PLEASE HELP!
I have a 98 c5 which drove fine all morning. Then came around evening and was parked for about 30 mins. I tryed to start it again and nothing happens. I thought it was the starter but thats a negative. Jumped start the starter and their was nothing wrong with it. Oh was driving that morning I noticed i had water squirting out somewhere on the passenger side. Somewhere behind the glovebox or something. I tryed looking for the spot but couldnt find it. anybody have a clue? My battery and alternator is brand new bought like 4 months ago. I think im not getting enough power but not really sure. The light under the hood and radio shuts off when i try to start it but the lights inside stays on....i have codes to post up later thanks

Sounds like your condenser drain for your air conditioner is blocked, do a search in Bill Curlee's sticky in the tech section.
Found it for you ...Post #3 I would read the whole thread on leaks, great info

OK... now you need to read Bill's write up on leaks (post #3). You need to dry out the interior and make sure you put a fan inside the car to dry out the electronics under the passenger foot well. You will also need to make sure the condenser drain is clear. If you have access to a lift it makes the job of cleaning the drain tube easy. If not you'll have to jack the car up and use jack stands to reach the tube to snip off the end. You can reach it and try and milk it clear from the top, but the best solution is to remove it and clean the tube and as mentioned, snip the end off. You're in a warm damp weather area and this will be a problem till corrected.
Your first code may be due to moisture in your BCM , also the RDCM is Loss of Communications with BCM , dry everything out and clear the codes they're all H (history) .
PS. When finished make sure there's a puddle of water on the ground under the right front fire wall, after running the air conditioner.

True. If the BCM gets water into it, nothing is going to work. Get that entire area carefully dried out and the source of the water fixed immediately. If you found water on or in the BCM, there are further options that might become needed such as cleaning it out. Doing so involves a lot of seriously careful efforts and knowledge BEFORE you attempt it. Let us know what you find first.

Turning in soon but check the udder from the cowling, it is located on the engine side of the firewall near the battery housing. Mine was clogged and water entered the cabin in all the wrong ways.
405.620.1297 in the next few minutes or tomorrow. I might be able to cut down on the trouble shooting.

Ok i air out the whole passenger pit. But im still getting the same result...NOTHING!
Anymore ideas of what it could be? I still think im not getting enough power because the starter is not cranking. The car is not turning over at all.
whats that box on the left for? Because i think moisture got in that. when i try to start it i hear that box clicking. Is it soppose to be clicking?
and whats that vent on the upperleft side is for? I had something in that so i dont know if that was the problem for the water leak inside.?

Ok, lets back up a bit. First, pull your codes and report all of them and be sure to add the H or C parts of the codes. Second, is the security light on the IP Cluster, flashing or steady then goes out? When you turn the key, do you hear a single click in the passenger footwell? Does the starter do anything at all such as a click? Put a meter across the battery with the key off and measure the available voltage. You need at least 12.5vdc there for the car to even think about starting.

28-TCS C1255 H
40-BCM B0507 H
B2587 H
B2592 H
A0-LDCM U1064 H
A6-SCM B0856 H
The security light stays flashing like normal when i have the door open and the key is not in the ignition. If thats what you meant. I hear one click when i turn the key to "START" and another click when i let the key go. I hear one click when i engage the key to "ON" position. And One more click when i take the out of the ignition. The starter does not make any noise at all. I dont think theirs any power going to the starter. IS their a starter relay in this vette? if so, where? or my soleniod could be bad?

There is a relay on the passenger side floor board that i replaced when i had my no start problem. I believe its called the tdr relay. Its been a long time but i do remember it has something to do with the starter. I found a pic of it. Its just above the BCM (Shiny metal box on the left)
C1255 H-EBTCM internal malfunction. Small problem but probably not related to the no start.
B0507 H-RH DRL Relay Circuit. Again I dont think is related to the no start.
B2587 H-Column Lock/Unlock Drive (A). I dont know too much about this one. Hopefully someone will help out with this one.
B2592 H-Column Lock/Unlock Drive (B). Same
U1064 H-Loss of Communications with BCM. This is the Left door control module. Again i dont think this has anything to do with the no start.
B0856 H-Unfortunately my collection of codes doesnt include this one but its the seat control module.

If the security light remains flashing when the key is in the ignition and its turned on, the car will not start. Its telling you that the key's chip was not read by the BCM. Now its still possible that the BCM is having issues. Not sure if you said this already or not, but did you check "all" of the fuses on both fuse boxes? The loss of comm with the LDCM is possibly important in this case. Please check inside of the driver's door's accordian tube for a wire there that possibly will short to the frame. I'm not sure that it would prevent it from starting up though.
As mentioned, the TDR relay is what actuates the starter solenoid. DO NOT Close those contacts manually unless the car is out of gear because the engine will turn over!!! I suggest you check the TDR relay and listen/feel if its turning on when you turn the key to the start position. If it isn't turning on, then we need to back up to the BCM again. Was there any water on it or possibly in it?
