The brake lights works fine when my head lights are turned off. The tail lights are brand new. Turn lights works fine when lights are on. Just the head lights don't work. Everything works when the head lights are turned off.
where is the mass air flow sensor located on a 1991 Isuzu 2.3L pickup engine? Picture if possible. New fuel pump and filter. New head and intake gaskets. Starts and runs for about a minute then dies and won't restart for 1/2 hour or so.
