Got this 69 Dart today but is it 68 ?

I like the blue.

Ok, here is how you go about checking where your problem is:

A combustion engine needs three basic things to start:

1. Fuel
2. Air
3. Spark

If you are getting all three of these, the engine should start, you may have to adjust the timing if not.

1. Fuel
Cycle the throttle linkage and check to see that gas is squirting in the carburetor. If not try putting some in a cup or jar and pouring it down the carb with the throttle open before cranking to start it. It may then start and then die within a few seconds. If a car has been sitting for a while, you may need to do this a few times to get the fuel system "primed". If it doesn't fix the fuel problem after a few tries, then consider replacing the fuel pump.

2. Air
As long as the throttle works and opens up, you are getting air.

3. Spark
Check to make sure that you are getting spark. To do this, I like to take a spare spark plug and pull off one of the spark plug wires (longer works well), then put the spare plug into the spark plug wire boot and then hold the bottom electrode of the spark plug to a good ground. Have someone crank the engine and check for spark (or leave the key in the "on" position and use a trigger start". Are you getting spark?

Yes: reconnect the spark plug wire back on the plug that you took it off of and try to start it. If it doesn't start or is sluggish, remove all spark plugs and either clean or replace them.

No: Pull the coil wire off of the center outlet in the distributor cap and hold near a good ground with a slight gap and then crank the car over. Look for spark jumping to the ground. Are you getting spark?

Yes: consider replacing the distributor cap and rotor, then connect everything and check for spark at spark plug.

No: Take a test light and verify that you are getting power into and out of both sides of ballast resistor. You may need to replace the ballast resistor and then check for spark at coil wire and at plug.

Hope this helps you track down the problem.
