Starting Problem (runaway starter/starts and dies)
Thread bump in hopes that ACR Man - OR someone - has the answer.
I have two 5.7l 2008 Tundras and I live in Nebraska. One is a CrewMax that I've owned since 2009 and my wife drives it. The other is a TRD I bought in September of 2013 to replace the 1999 Silverado that I drove. We've never had a problem with the CrewMax BUT I HAVE THIS EXACT SAME STARTING PROBLEM with the TRD. In my case it occurs only during the winter - it occurred several times last winter and has just begun again.
Initially I thought that it was a problem with the transponder key so I swapped keys and that didn't help. Next I thought it might be a problem with the anti-theft system because I had similar problem with a 1999 Chevy Malibu that required me to pull the key, wait 10 minutes and then it would start, but there's no flashing code prior to this phenomena to indicate that. So the next "keep it simple" thing I think it could be is the shift from summer blend gas to winter blend gas here in the North. So I'll do a fuel filter change and switch gas stations to see if either help. After that I'm at a loss.
I've spoken to the dealer (they do my oil changes) and to a local private shop that's done my "heavy" mechanical work for 30 years. The dealer "has no idea" and wants to me bring it in - my gut tells me that they know WTheck is going on but want the service charge. The local private shop hasn't seen this problem.
So please, if anyone has the answer to this mystery please help ACR Man a senior citizen from Nebraska out.
Kind regards and Merry Christmas,
Doug - Old man from Nebraska.
