Engine problem my 2001 toyota avalon will not start. When I put the keys in and turn it all the way up, all of the lights will come on but it would not start. I have to try like 8 or 9 times to get it started. the battery is new, We even changed the spark plugs to see if it was it, . and still having problems starting the car. anyone please help.

If the engine is the same as my 2002, they are a Hemi-style which go right into the valve covers, hidden under the individual coil packswhich can be removed by loosening one nut I believe. After you remove the nut, pull straight out and you will see the Spark plug cap is attacked to the bottom of the coil pack, use an extension and a spark plug socket preferably with a rubber grommet inside it or you will play hell getting the plugs out of the wells once they are loose.

You have to use a scanner and pull the code out that is causing the check engine light to come on. whatever code/codes you find are probably related to vsc light.
Good luck and keep me posted
