not sure about the sulfur smell,but when my truck acted like that it was the pick up coil in the distributor. i am not familiar with 2 digit codes,but you could find out what they mean at Ford Fuel Injection

when u pull the vacuum line off the egr valve there should be vacuum on the line if u rev up the engine right? i never had vacuum at all and iv got codes for the egr valve position sensor and valve not opening .

well i think my cat is clogged i checked the vacume at the tree with the engine running at idle. around 18 hg when i spike the throttle the vacume drops to zero. when i rev up the engine to 2000 rpm i get no vac at the egr valve line . so i think i have a faulty egr vent controll valve its 2 days old.when i had the vacume guage on the tree with the engine. running 'hot 'when it usually dies the vacume droped to about 15 hg just before it died. so im gona swap some parts on this thing and see what happens tomorow.

to kill a cat, u must have multiple problems. this might not be easy. Better get a Haynes manual and save FTE to Favorites.
Start with basic timing, pull SPOUT jumper out see if timing is close. Erase codes, and keep checking as you troubleshoot. These trucks spit out occasional codes, even when running well, KOEO codes can be weeks or months old.
Check vacuum lines, vac lines control engine emissions systems
Don't start throwing money away. Check one thing at a time, and be damn sure it is broken b$ swapping it out. Fix one thing at a time!!!
Don't strip the engine down to the block and rebuild. You may have a misfiring cylinder, dumping raw fuel intpo the cat, possible bad wire or broken plug! CATS hate raw fuel..it tend to make them glow red and melt.
You can pull spark plugs and smell check for fuel, and see if any plugs are fouled too..very good test.

As cjben said, I believe you have a bad pickup coil, aka stator assy, aka ignition pickup inside the distributor. I believe it is easier to replace the whole distributor. And for future reference, when you have that many error codes, disconnect the negative battery cable for a couple of minutes to reset the computer and erase error codes. New codes will present themselves after a short drive.

ok so with ignition on i poped the cap and rotor off and wiggled the cup or disk and u can hear the fuel pump and relays powering over and over again basically cuting power out to ignition so im guessing as u huys said the pickup is gone?

It sounds like your pickup is working.When you turn the key on you should hear the fuel pump come on for a couple seconds. When the computer gets a signal from the pickup (from engine cranking or you moving the dist shaft) it turns the pump back on. Have you checked to see if you are getting spark? I would suspect the ignition module over pickup coil, I've replaced a bucket-load of them over the years and maybe one or two pickup coils
