My truck want start
my 2002 f150 want start.put in a
silenoid starter battery altenator.
After one day battery is drained.
What could it be??Also the check
engine light is on
Rebuilt starters could be bad out of the box but that would be a long shot. Jump start the car to get it running. Use a multi-meter and make sure the alternator is charging at least 14 volts, or slightly more, to the battery. If the alternator is charging then suspect a parasitic drain, but it would have to be rather large to kill a new battery in one day.
