Okay it started with theother night turn on headlights and the truck starts shimmeying and sputtering like no fuel flow mind you it is equipped with electronic fuel injection now it sputters when headlights, turn signals, or hitting brakes even dies when i stop here clicking from engine control module on passenger side could it be the efi relay or could there be a short somewhere alternator was replaced last month the only time check engine light ever comes on is when driving and using turn signals please help me solve this headache.
