Do the simple things and eliminate those first..maybe find the answer therein. Do you have an electric fuel pump (with 2x2, I assume you do?). If so, what is pressure setting pounds !
BTW...this may seem elementary, BUT make a check list and check off 'things' as you go along and like a map will keep you on track and possibly lead to solution. If you are like some of us with older/fuzzy brain cell, maybe helpful  |
