have a 1993 isuzu V6 3.2 liter engine, car starts normally, after one or two turns in the morning
in the late afternoon, it often takes three or more attempts and even then, the initial revolutions are barely audible until the revs stabilize after 30 sec or so
have always filled at the same station, use regularly a small amount of fuel additive to keep injectors in shape (since car was new, so for 13 years)
plugged up filter? broken fuel pump? anything else to look for?
