i figured which wires needed to be changed to make coil fire and fuel pump to come on but now there's only one problem......

the anti-theft decoder and the resistor in my key does not match up with the v8 computer.... this causes the engine to crank up for three seconds then shut off..... is there any way i can take my car and computer to a dealership and let them reset my computer to match my old v6 key and decoder?

or do i have to get the decoder and key out of the car that i pulled the engine out of?

i appreciate ANY suggestions
