procharged 454 wont run
 

so I am cruising along at about 3k rpm when stbd engine starts sputtering and quits.
So far checked water fuel seperator and no water. Fuel pressure from mech pump about 7 psi to carb.
Pumping accelerator pump fuel goes into carb.
Quick checked spark with screwdriver in coil wire and sparks but did strikes me as too orange and not blue enoigh.
Tomorrow will use timing light to verify if spark is getting to plug wire and at the right time.
I did replace cap rotor wires and plugs this spring and have run a few hours since then.
Any sugestions are appreciated.
