Need help ... car won't start

I'm new to this forum but not to mustangs ... have a Mach 1 and a Bullitt in the garage. Picked up a 94 GT convertible driver off eBay with lots of miles but "ran" great. Drove 300 miles home and no problem. Trying to "clean it up" a bit I Gunked the engine and used power washer to finish the job. Since then ... problems. The scenario is that the engine will start although horribly mis-firing. After running for 10 minutes it got to sounding pretty good so I shut it off and now it won't start. If you put the gas pedal all the way to the floor it will start but immediately shut down. I've checked for water everywhere ... even running a hair dryer into distributor, and all intake related electrical fittings and still the same problem. All vacuum hoses appear to be intact. Anybody have any ideas where to look? Appreciate the help. Thanks!!

Thanks for the reply nmcgrawj. 35 lookers and 1 reply seems a little strange. Perhaps I'll take your advice and seek assistance elsewhere. Finally got it to start again today after sitting over 24 hours. Same darn thing ... rumbled and sputered for a few minutes, then smoothed out and let it idle for 25 minutes. Turned it off and won't restart. Huge smell of fuel coming out of the exhaust so apparently fuel is flooding one or more cylinders. Injector problems maybe? I don't have a clue. Again, thanks for your thoughts. JP

Thanks to the miracle of WD40 ... and you gotta love the new swivel straw nozzle ... I sprayed a good amount down in the distributor on the PIP and the beast came to life albeit still a bit ragged but at least starts right up. Still bought a new MSD unit from Summit ... the basic Ford replacement ... so should be a full up round by the weekend. The answer was as Nate pointed out on corral.net but still my thanks for your comments.
