did you really put a rotor back in? Sounds silly but I have seen it happen more than once.

Is the dist cap on completely. had some that did not set back on the distributor very well. Usually got some popping though but still a point to check.

have you tried to check for spark directly from coil? Power to coil?

what kind of car and engine?

If I was in your shoes, based on what you are telling us...this is what I would do:

I would locate the timing mark. I would remove the distributior cap and see that when the engine is rotated to point to number one cylinder at the distributor tower,l the timing mark says 0.

I'd also check the compression.

(What did your plugs look like for color when you replaced them? Were they sooted up with black?) Have you tried repulling the plugs to see what they look like now, after you changed them?

The stuff I mentioned is where I would start...for starters. These are a few real basic things to know to rule out many things.

I had a car where, of all things, the car ran fine one minute, and then didn't the next time. I ran the checks I just said. I was also getting backfire through the throttle body injector every 2nd (or something) revolution of the engine. I concluded a valve hangup or stuck problem. In minutes I had my valve cover off, and found the problem; one roller rocker fell off and was down inside, unharmed, due to lack of hydraulics to the lash adjuster. I was able to force the roller rocker back on with giant channel locks and I was on my way. And have had no similar instance since, in thousands of miles on a 231,000 mile 4-banger engine that runs like a top
