New engine, won't run!

Uhh...are you absolutely positive you're getting fuel?
Will it start and run when a dab of fuel is poured down carb?
I've seen guys chase problems only to find out that either the fuel pump isn't pumping, clogged filter, vaccum leak or the carb has a stuck float.

Or there is air in the fuel line and the pump isn't getting any fuel to the carb.

hmm, - if the timing`s correct - and the distributor positioned corecctly, too. Fuel is there, - THEN I think it should be a defective spark module in the dizzy.

I have had exactly the same prob - I couldn`t imagine that I might have problems with the distributor because I actually HAD SPARK on the plug....

After I replaced the module it ran.......

Especially if it's a dual tank truck....if the fuel valve has a small, internal leak and one tank is empty, it's basically a vacuum leak and no fuel is drawn from the tank with fuel....
I just fixed this problem on my own truck after much frustration trying to find the issue...
