78 Grand Marquis Won't Start

Hiya. I could have sworn I posted this yesterday, but I guess not.

I have a 1978 Grand Marquis, with a 460 v8, and it won't start.

The carbeurator, voltage regulator, and all the wires are pretty new, so I don't think it's any of them. I checked the fuel line, and fuel is getting to the carbeurator, so I don't think it's the fuel pump. I checked the battery, and it has a full charge.

It sounds like it wants to start. It goes "Vrum vrum vrum" (I don't know how else to describe it), but it won't start up.

Anyone have an idea of what I should check next?

Thanks,
Emily

Is your duraspark box completely bitched? It's usually on the drivers wheel well under the hood. I replaced this when mine was getting uppity and all was well after. Then I just changed everything to MSD because I like to spend money. Also make sure that horse shoe looking clip on your coil is seated properly.

Best of luck.

The stunning silence either means it works or you gave up. :-)

Indeed. He said the wires and such are pretty new so he didn't think it was any of them. If the engine is turning, and fuel is getting to the carb, then the next thing to do is actually CHECK to make sure you have spark at all the cylinders. If not, then check all ignition parts. Also, it's a 78, they still had distributors. Check the distributor to see if it came loose, turned, or is generally out of the proper timing position. Gotta get old school, heheh.

If you're still reading this, if you have an old spark plug still, pull off a boot, I guess from #1, put it on the loose plug and ground it to something away from the carb or battery and crank it over and see if you have any spark.
