Need Help!!!!! Dodge intermittently will crank but won't start

Tried stomping it to the floor and pumping it. It kept acting like it wanted to start but it never did.
I disconnected the PCV valve from intake manifold and hooked up a vacuum gauge. I tried cranking the truck but when it would not start it only had zero vacuum every now and then when it would try to start the vacuum would immediately drop to 5 inches mercury. I could not tell which was occurring first either the vacuum or the starting but the two seem related and maybe causing the other.
I woke up this morning and watching the vacuum gauge the truck fired right up but was skipping a little and vacuum was at 30 cm of mercury. It spit and sputtered a little and then all of a sudden smoothed out perfect at the same time the vacuum went to 40 cm mercury.

Ok well I am almost embarrassed to say but i think it has just been flooding this whole time. It would not start so we decided to pull the fuel pump relay and crank on the engine awhile. We then reinstalled the relay and it started right up.
We tried the wide open throttle while cranking but maybe we didn't hold the throttle down long enough. We were holding it down for maybe 20 seconds but next time i will try a little longer. I'm guessing now that we may just have an injector or two leaking down.

I think I am going to go get some used injectors from junk yard today and try but first I would live to know how to get a strong blue spark. I put a new coil, cap, rotor wires, and plugs but its still just a weak looking yellow spark. Should I buy an aftermarket coil Lil MSD or something?
