[A/S] Thanks for help from Suburban owners

["Tricia & Conrad" <triconholsomback@xxxxxxxxxxxxx>]

Hi All,
Thanks for all the help and advice.
The local Chevy dealer finally found our problem! It took them a while to find it too!  
The main engine ground was corroded.  They cleaned it and replaced the bolt that attaches 
it to the engine. 
Like Kimm said, the dealer charged a lot, but we were not physically able to do the work 
even with our adult grandson's help.
Hope our experience helps.
BTW Good Sam Highway Roadservice sent a tow truck each of the three times it wouldn't 
start, no questions asked!  Hopefully they will renew our service next year.
Again, thanks to all who responded
Tricia & Conrad
