This year has been problem after problem with this Nova. Here's deal car starts but will not stay running. You keep your foot in it stay running for little bit. Then shoot flames out carb and quits. I tried several Holley 600 v/s/carbs but same problem. I tried 750 Holley v/s it stayed running , idle real nice but no power. I pulled plugs thought they would wet. Nice tan color and dry. No vacuum leaks. What gives. Is it possible for mechanical fuel pump gone or going to hell.
