...well that is a puzzle, do believe that your hazards should work at any time...I should suspect undervoltage to the lighting buss because of a old battery and/or a weak connection from 1/0 battery cable to ground and back to the engine...this connection is responsible for 300 cold cranking amps needed for starting~ the under-voltage is the cause of your problem...bad battery and weak alternator and lack of 300 CCA connections is the cause~
Blinkers do not work while driving...BUT if you turn truck off and turn ignition to AUX. they work just fine??

My husband recently changed out the fuel pump and now it acts like it's out of gas. Now the starter or ignition system acts like it wants to start, but it doesn't.
