as you have already read in the title, my car wont start. 1998 jetta mk3 2.0 5spd. when i put the key in the on posistion, i dont get the check engine light like youre supposed to. the bulb didnt burn out, i know this for a fact and it come back on ever once in a thousand tries. whenever the CEL isnt on it wont start and whenever it is on it will start. sometimes when it does start it runs rough, others its pretty normal. i tried to put my scanner on it when the CEL was out but it kept coming up with a comm error and when it is on, i get no sort of codes or anything. any ideas? it didnt start happening untill i started banging out my sound deadener from the floor and under the dash. i cleaned my battery posts and cables and the ground to the trans and starter connections. startin to get frustrated. any help would be nice. thanks in advance.
