[WB72]

I am a bit baffled.
I have a strong 383 built up and a few weeks ago it started to intermittently run bad, almost like a miss. As i was trying to diagnose the problem, the truck no longer starts. When it was running (badly) I checked the headers with a temp gun and were all similar in temperature, so it wasn't a bad plug.

I have HEI ignition i am thinking it is in good condition, is there someway to check the components?

I have heard it might be my ignition switch, what should I check to verify that?

There is fuel going to the engine, because it doesn't take long to smell the fuel when it is trying to start.

Any help will be very much appreciated.
