Won't Start

84, 5.0, 4V, mechanical fuel pump, won't start. If you put some fuel in the carb it will try to kick but won't stay running so I know I have fire.

New fuel pump and fuel filter. Fuel is coming out of the line at carb, what next? Car did sit for awhile, about 90-days and was fine before that.

Any ideas of easy things to checki?

Thanks... that was what I was hoping was not the case.

How hard is the Holley 4180 to rebuild and then set-up on the vehicle? I have rebuilt simple carbs before, but I thought I heard that the Holley's take a bit more skill to get thge rebuld and set-up right.
