Hello all. Thanks for having me on the forums and thanks in advance for any help you may render.
Some time back, my 2007 TrailBlazer threw code P0449. I ran with it for a several thousand miles with no noticeable negative consequences beyond diminished gas mileage.
After a little research both online and at the parts store, I sprung for the Evap Vent Solenoid (<$25.)
Despite having to wiggle my sizable self under the back of the TB, it was one of the easiest parts swaps I have ever done. One vac hose, one electrical connector, and the whole thing went on a metal piece that didn't even use any bolts or screws. Piece of cake!
I disconnected the battery for a few minutes, reconnected, turned the key to run for a few minutes without starting the engine, then turned the key to start.
It didn't start. It wouldn't start.
The engine will turn, but will not start.
Here's what I know for sure:
1. Other than being due for an oil change, the TB had no other problems or symptoms I know anything about.
2. I checked my electrical and vacuum connections on the new part, they seemed fine. I took the new part off and put the old one on. It still wouldn't start.
3. Through all this, despite the close quarters, I did not abuse the vacuum line or electrical wires, and I don't believe I pulled on them in any way that would have caused a fault.
4. I have disconnected the battery for over a half hour, reconnected. No change in the problem.
Any helpful information, insight, or wild guesses will be much appreciated.
Thanks
Billy
