WFT no spark on #1 till higher rpm

WTF could be wrong now .. fasturn HSR 300+ign and coil . msd dist. new wires new plugs new ign module.. I went to check timing again just to be sure when idling 1# has no spark .. so i put a different wire on same thing .. clip timing light on #3 timing light light works great.. Now when i rev the engine to 2000 the dam #1 wire starts working.. Any ideas maybe a bad coil? or what else could it be??? Thanks

The coil works or it doesnt. It cant narrow down one cyl to ignore

If the other cyls are firing correctly, check for a damaged cap/rotor

Try clipping the pickup near the dist and see if it works. My POS timing light works like this.
