no fuel to carb on crank

Make sure the fuel evap control is intact and venting properly. The 1/4" tube coming from the tank --up into the engine bay--and interfacing with the carbon can system IS THE VENT on those cars. Also you must have the proper "pressure vacuum" fuel cap. If any of that is disconnected/ plugged/ etc etc you might be pulling a vacuum in the tank, causing the think to "suck" fuel back.

Latest shop manual I know of for free download is the 73, and there might be "some stuff" different RE the evap system, but you can download it from MyMopar
