I'm sorry you have had to spend so much money. I know that hurts. I have done nothing. I'm at a loss. But since you mentioned the security system, that leads me to wonder what would happen if you pulled a fuse, if there is one, for the security system. I'm not sure how you would check that. Did you your mechanic give you any tips?? Thanks Don

thanks for the support. the security sys. is one that is installed by chev. people. i asked my mech is we could bypass it and he said we could, but that the engine would have to be re-wired. he also said something about that the system shuts down something in the engine (he knows what it is--I forgot!!) if it thinks it is being stolen. he has checked with a few of his mech. friends and everyone is at a loss on this one. i thought i'd get online to see if anyone had any suggestions on what to do. what a mess!! darn those chevy people!!!

I've also heard about relays getting too hot and causing the stall, but I think that would need to checked out by Auto Electric people. This seems to conform to the fact that the stall usually comes after the van has been driven, parked for a while, then is being driven again.

i spoke to a master mech. with gm last night for about 2 hours online. he said it all sounded very strange to him and i need to get a code for him to help me any further. this means it needs to rain or get humid again causing my van not to start, and having it towed in to get the code out. what fun!!! i will check with my intown mech. about the relay thing. thanks again for all your support!

I have a van that turns over but won't start when it gets cold outside or if the weather is rainy or humid. I have changed several parts and it has been at the dealership several times. They are now telling me it is no long under the warrenty and I am still having the problem. Any help would be much appreciated!

Hi Their
  Did you ever figure out what caused this? My 02 Express, 4.3 V6 Vortec is doing the same thing. Sometimes runs for days, sometimes when sitting at the lights it stalls, then wont re start. If you wait for 10 minutes or so, starts right up and drives great. Maybe 3 hours latter, same thing. Computer shows no codes or errors. GM Dealer has no idea as they can't get the van to stall on the road test. Sometimes runs for 3 or 4 days. Sometimes stalls 3-4 times a day. Dosnt matter if its raining, cold, sunny, snow makes no difference. Fustrating as hell.

I have a Savana and I love it when it runs! I talked to some one from GM today and they told me that they have not received any other complaints like what is happening with my van. But my father-in-law has a half back which is the same vehicle and the same problems as mine. He is very smart when it comes to these types of problems and still can not figure it out? I would be very careful if you purchase one.

I noticed my key was wiggling in the when trying to start up. I had the van towed when it stop on me. The mechanic said it sound like a shortage within the steering. I noticed they had tighten up the inition switch, and so far after 3 month it has not stop. I have always thought something was wrong within the key inition switch.

If you have a Autozone near by you can stop by and borrow their code reader. They loan it out for free to anyone. This way you don't have to get your van tow and you would be able to get the code for your mechanic. Lately I have been having similar problem with my 1998 Express 2500. Seems like for no reason at all it will refuse to start then after a period of rest then it will start up just fine. Have not figure out the problem yet. I try tighten up the battery terminals and that was okay for about two weeks then this morning it refuse to start again and I have not had time to look at it yet. If you have any further progress please keep me posted and I will do the same.
