This is about a 2007 Impala with a 3.9L and 148,000 miles.
I was driving down the highway and suddenly noticed the "service traction control" message came on and the check engine light was blinking. I had driven over 500 miles for the day at this point. I looked in the rear view mirror and saw white smoke coming out the back. The temp gauge indicated the temp was right at normal (i.e. needle was at half way).
I pulled over and popped the hood. I didn't see anything wrong with the radiator hoses. I then saw the white smoke coming out of both exhausts. I tried to start the car and it turns over, but will not fire.
Get it towed and it is dark. The tow truck driver and I see no evidence of a blown head gasket.
1) No evidence of coolant anywhere outside the engine or on ground.
2) No sign of coolant on dipstick.
3) i do not see any oil in the overflow reservoir.
I did not remove the radiator cap yet. Tow truck guy said it seems odd the temp gauge indicated there was no overheating going on although it could be wrong. One thought is perhaps there is a coil pack problem or a fuel pump issue.
I am sick with worry about this and would appreciate amy feedback.
The car will turn over but not start. Tow truck guy said this does not sound like a coil/ignition problem.
