I have a 1993 pontiac trans am with the lt1 and i have a starting problem.
When its cold it will start and drive fine but
once it gets warm it wont start at all unless i
pump the gas pedal a couple times and it
will shut off while im driving and if i wait 5
mins it starts again.I cleaned out the throtte
body and changed the fuel filter.Could it be
the fuel pump??
Try adding some fuel injector cleaner to gas tank
