Default Now what did I break?

I have a 94 TA with a corvette lt1 and a turbo 350, ported vet heads, lt4 hot cam, long tubes, 2000 stall, that about it. I had the injectors tuned to dump as much fuel as possible, stock lt1 injectors. today i was crusing at about 3000 to 3400 rpms, suddenly i realized no matter how much gas i gave it the car did not move, nor did the rpms jump. however the engine was still running. shortly after realizing this my car backfired and shut down. my friend suggested the inginition modulator, or possibly my O2's. Any other ideas?

Why the hell would you have it tuned to dump as much fuel as possible?

Because it is a corvette motor and they need extra fuel for all that extra power.

ok he didnt have them tuned to dump as much fuel as possible, he sent the computer to MadZ28.com and had it tuned for his mods and have noticed that if it primes the car does not want to start and sitting at a light it smells like gas pretty bad.... He had it wrong but not a big deal... the Dealer just called and said the opti is full of oil what the hell would that be... all the seals and **** are new on the timing cover and he's not leaking any thing...

there is a o-ring seal on the water pump drive and if you dont know its there and install the water pump good chances are you tore it. If you do this it will leak oil all over the front of the engine and opti if its not sealed.
