too much fuel
i purchased my first sc 400 95 a few months ago.it stalled later and i took it to the shop.no lights on dash and no hard or soft codes shown either.so i decided to do a full tune up.water pump.belt tensioner,caps,rotors,plugs,timing belt,etc.this made the situation worse.so now the shop added that it might be the ''low coolant temp sensor'',so that was replaced.no reward!!!!!!!!!!!so i even went on to do injen intake and new mass air flow sensor,no reward.only thing left is the two coils and and two ignition modules on drivers inner fender well.i've spent so much money and still my car doesn't run right.apon start the car floods out like its not burning the fuel fast enough so the plugs flood right out.wheels,front/rear after market lights,glassed radio face,led through out front and rear with low hids and fogs,carbon fiber hood and trunk;i went to far to fast.i'm so far in that i don't know what to do.any suggestion,please feel free.....

If it's flooding, could be clogged fuel pressure regulators. If they're not letting excess fuel bypass, you get high pressure at the rails (easy to check) and it'll run rich, especially at cold startup.

Please tell me what you mean by hard or soft codes?
My engine light stays on when my key is in the on position----it stays on after all the other lights go off---but when u start the car the engine light goes off immediately-------is that a "soft" code?
Please elaborate----thanks------and good luck with your issues.
