OK here is where I'm at. I took my truck to a big garage (city) and had a friend hook up a bazillion dollar scanner to the computer. NO codes, none whatsoever. I'm still having to spray starting fluid in to get it running. IAlthough the battery seems OK, I'm replacing it.I am (almost) completely convinced that this is the problem. I just can't find anything wrong or anything bad. If this fixes it, I am gonna have this stored in memory FOREVER. I talked to probably 10 mechanics who grilled me over this, and they are buffaloed too. Only thing left is the friggin battery.Every question they asked was answered with a "I did that". It runs fine once started...so it HAS to be the battery, right? I'll post tomorrow once I have that done.
I just want to thank EVERYONE on this board who have helped me on this problem. I'm a LOT more familiar (although I don't know if thats good

) with this 4.3 Vortec now. I'm gaining some confidence.
God, PLEASE let it be the battery...otherwise I'm completely lost.
Thanks guys....
Jon
