My truck starts excelant first thing in the morning.I drive 6 miles to work. When I go to restart it an hour later, it turns over but won't start. If I give it gas it will start but sputters abit till clears out.I've tried the 10 second key on, off wait and key back on 10 secs. It will start right up most times ( 6-10).A new fuel was put in app. 2 years ago.

Hi:
This could be caused by many things. As a result, I recommend having the computer scanned for trouble codes at a nationally recognized parts store. They will do it for free, and it will help direct us in the right direction.

Let me know what you find.

Joe

Jacobandnickolas,

Fuel pump tests 60 lbs warm, fuel regulater good, Took throttle body off and cleaned. Idle air control test ok, Throttle postion sensor tests ok but could it be out of calibration?
