Random no start condition: it will start and immediately die, only seems to do this during warmer temps (June- September) I wait approx. 20 minutes and it will start and stay running. Has not happened to me during winter months. It has had this problem since purchased in 2000. It had remote start disconnected thinking this might have been what was causing the problem. I have replaced the fuel cap, had codes pulled there were no codes, fuel relays were checked, fuel pump seems to be working properly. It happened yesterday after work at 5:30 pm, temps were in the mid 80’s. I noticed yesterday that the security light was on when I drove it on errands and at lunch, it started fine both of those times.

temperature related would lead me to think either the temp sensor is faulty or the IAC – Idle Air Control Valve is sticking. Neither would produce a code.
Do you think the security light being on has anything to do with it?
not if it acts the same when the light is out.
If it didn’t start acting this way until the security light did come on and stay on, then yes.
