hi guys need some help. recently my vehicle lost a lot of power
i would say about 50 % so this is what i did .i bypassed the switch over valve for boost enrichment ,so the vacuum line goes from intake manifold to at ALDA (boost enrichment diaphragm) still no power . checked boost pressure 12 psi
my question is , is it the diaphragm ,or internal fault in the injection pump ,need some help thanks .
