Will not start with out staring fluid
coil and ballast resitor is less than a year old.
WHAT YEAR/ MODEL, and POINTS OR ELECTRONIC ignition??
They might be ONE DAY old and still have a problem
In addition to the suggestion about looking for the acellerator pump shot, check your spark quality.
Get a helper to crank the car WITH THE KEY, NOT jumpering the relay. (This operates the resistor bypass circuit.)
Remove the coil wire from the coil, and "rig" a probe. You can use a clip lead and a screwdriver, or your 12V test lamp.
Ground the clip, and hold the probe up at the top of the coil tower. Have your helper crank the engine, and look for a nice, fat, blue spark.
If not, you have issues, wiring, coil, resistor, or the bypass circuit is AFU. Your suspects are the bulkhead connector, connector at the IGN switch, the switch itself, or the coil.
If you have points ignition, could be bad points or condenser.
Could be low voltage to the IGN system. Use your meter, at the coil + terminal. With your helper cranking the engine WITH THE KEY, measure the voltage, should be very close to "same as battery" and in no case less than 10.5V
IF the spark at the coil tower looks OK, move on, pull and inspect the plugs. Use your ohmeter to check the COIL wire as well as the plug wires. The "old" rule of thumb used to be 1000 ohms per every foot of wire, but in practice, they are usually lower.
Inspect the cap and rotor, condensation, oil, junk, dirt, carbon tracking, etc. take a CAREFUL look at the rotor AND the UNDERSIDE of the rotor.
Problems such as this are almost always the result of:
Poor engine condition, low compression, burns oil, worn cam, timing chain, etc
Poor engine tune, ignition, carb
Poor / stale gas or contaminated gas
