GM question? Problem !!

Small Block said

A lady bought a 01 Camaro with a V6 and she has lost confidence in it as sometimes it will not start. Nice car but she can drive it for a while, to the store or down town and everything is fine but then she comes out of the store and gets in and tries to start it but no dice. It's an intermitant thing. It's been to the dealer and put on the computer but they cant find nothing on the codes. It sounds electrical and she's tired of giving these guys $75 just to look at it. That dont include the price of fixin it if they did find something wrong. Any ideas guys. I know on our Mopars the electronic box has jacked with me in the past. Is something getting too hot? Shoot me some ideas and i'll try and help the gal out of a bind. Thanks.......OH and go ahead and give me some GM raggin....I'm ready.

We had gotten a blazer for our son before I bought his 69 dart. On test ride it ran fine. One time we went to restart and nothing. Was told to wait 2 min and try again. Started and ran fine. Happened again before we left but took longer wait. On the exit ramp to our home it quit. Towed to dealer. CFI Unit.
One of the versions of the centralized fuel injection system has an injector with 6 legs (hoses) for each cylinder for fuel. Lots of people call this a spider or spider injector. $900.00 at the dealer. Was told the way these go bad is they intermit. won't start after warm up. When it fails you turn key off and wait a couple of seconds and try to start. As the unit goes into more failier it will take longer and longer wait to restart. When it's really getting ready for complete failier it will start dying while driving and then finally won't start at all.
1 year later it started doing it again and we sold it! They can be had for about $350.00 if you do yourself. It's under the part that looks like a intake manifold. I'm suprised it's not showing up at test at the dealer.
That was our great GM feeling!!!!! Was absolutly the last time, never again, shitolet!
Just an idea...:-D
Good luck!
