Check all of your FACTS (Fuel, Air, Compression, Timing, Spark)

Check for +12v at the distributor when cranking.

Verify you have the correct TDC and not 180* out. If you remove the valve cover or are lucky enough to have the oil cap over #1 valves, you should see the #1 intake valve closing just before TDC, and the exhaust valve moving just after TDC. Movement should be nearly immediate when turning the engine by hand.

Verify that you have a squirt of fuel from the accelerator pump when the throttle linkage is cycled.

Verify that the throttle is cracked slightly (throttle lever resting on idle screw - no gap)

Perform a compression test to verify a healthy engine if needed.
