HELP !!! Motor Swap...Injector Problems!!!

I recently picked up a 87' GA 2.5L ATX with a engine that had been replaced. The engine had only 13k miles and was a BRAND NEW replacement, I got the car because it was completely rusted out. Don't know what the person was thinking after the $3,400.00 bill to put it in. I pulled out the motor and proceeded to put in a 91' GA 2.5L ATX, everything went fine until I went to start it up.

When I turned the key to the 'on' position the injector dumped so much gas in the throttle body it created a little pool of gas. I though maybe it was a freak thing, but when I went to turn it over it did the same thing while cranking. I tried swapping throttle bodies and injectors until every combination was tried and the same thing happened every time? I looked everything over and couldn't find anything I missed during the transplant. I am stumped and don't want to keep throwing parts at it because its just a BWAH(beater with a heater). Any info would be much appreciated!

Thanks,
Justin
