check the cap and rotor. make sure the 3 wire connector is on. make sure the power wire is in the right spot and not the tach spot in the cap

When i took the old one apart the red wire was on the right and the yellow wire was on the left, so i put them in that same placement on the new one. If thats what your trying to tell me, would i be looking at points-type ignition or HEI ignition?

I think i may have found my problem, i was going by points-type ignition because when i took it off wire #1 was on the left side of the tach cap i was sure, if the plug wires were in the wrong order could that be the problem? I know the firing order around the distributor is right, it could just be in the wrong spots??
