Maybe you guys can help me out . 2007 Suburban (Flex fuel) 35k miles on it . Was running fine then started giving me starting problems, it would not start on the first attempt ,it would take either 2 or 3 times to start . Service engine light came on, Stabilitrak, Traction control kept coming on and off . Dealer said it was the fuel pump and replaced it . Pulled out of the Dealer and 10 minutes later SEL came back on again , Stabilitrak and Traction control lights came on again, but truck has been starting on first attempt . Dealer said the spark plugs must have gotten burnt when the fuel pump wasn't working and gas was running lean , so they replaced spark plugs, but SEL was still showing trouble . They worked a long time on the car and couldn't find the trouble, called GM and after an hour and a half , they concluded that when the Fuel pump wasn't running right , the Computer thought it was running on ethanol and not gas they said they reset the Computer and it's fixed.I'm going to pick it up tomorrow morning and going on a long trip over the weekend ,I'm a little concerned about getting stuck , does what they say happened make sense ? Antbody come across a similar issue in their experience ? THANKS

 

I am have this same issue right now. Did resetting the computer fix the problem. I'm on road trip from wisconsin to new mexico

 

E85 is a scam by the gov't... to get us to buy more presents at xmas...

No, but seriously, I hate E85, and even E10 is destroying many older engine, especially boats that last 20+ years... it's BS.

 

Only reason ethanol is close to competitive is due to both a gov't subsidy on it and a heavy tariff on imported sugar based ethanol.

 

does anyone here actually run E85 on a regular basis in their Tahoe/Burb?
