Help needed STAT!

I think i might have screwed up some how......:(. i burnt a program to a new chip and installed it into my ecm via g1. apparently it wasnt down all the way, when i turned the key on the dash flickered(guages jumped a bit). so i turned the car off quickly. so i removed the g1 adapter from the factory memcal and placed the factory memcal back into the ecm. now when i turn the key on it goes strait to diagnostic mode (fans on check engine light on)no start. it acts as if there isnt a memcal installed at all. i cant get it to flash a code either. did i get the pcm? memcal? any help would be appreciated.

solved my problem....found a bent pin on the resistor pack on the stock memcal that was grounding a pin. must have been a little careless last night.:shame:
