'66 dart 270, 225 /6. points ingnition

I checked the spark first with a timing light clamped on each of the six wires. I also ran each one through an in line spark tester.

I put on a new coil, a new ballast resistor and even tried a new volts regulator.

I pulled one plug and checked for compresion (thumb over the hole, don't have a compresion tester) and felt pritty strong.

I don't think its timing cause it ran perfect the day before and nothing was touched. All vacuum lines look good and are connected.

tried priming it myself with fuel but nothing
