Need help, Dart won't start...

First things first, did you LOOK into the carburetor and verify that it's got fuel? Accelerator pump is your friend. Try to catch some and inspect. It's not water is it?

Second, pull a plug wire, hook up a spark plug and ground it, crank motor? Spark?

Is the distributor rotor turning when you crank it? Did the 318 run when it was pulled?

When I see this:
1971 Dart Swinger I just finished putting in my 318 (original /6 car). I checked the coil and it's good, ballast resistor is good, battery is good. I have new spark plugs and wires. It will turn over but won't fire, doesn't even try. Gas is pumping and I tried priming the carb, no fire.

Some background: The car then I got it wasn't running took out the 225 and put in a 1971 318, still has points ignition. I put new points and gapped it to correct gap and new condenser. My guess is something isn't right in electrical. Any help would be greatly appreciated.

The first thing I think is, "ok, HOW did you check these things??" you looked at it, it hasn't been stolen and is still present?

Did you break out a multimeter? If so, what values did you get? Where do you have voltage, and when, and how much? or did you merely touch and squeeze these components to insure that they aren't simply illusions?

SOooooooooooo many times..."yeah the battery is good. I checked it." ok. What is the voltage? "Oh it has plenty of that."

?? really? How much? "oh, plenty. I looked at it and it's fine"....

measure it. "Oh, it's got eleven, and about 6 when I crank it...."

BTW, 'new' does not mean "good". VERIFY that thepoints and related parts are functioning correctly. Got voltage at the points?
