First check all fuses in the battery fuse block and in the instrument panel fuse block. You might look at the owners manual for a fuse block daigram. Make sure that you have all the correct fuses and relays the correct locations and for burnt fuses. Does the battery have 12 volts?
Check all your connections for burnt wires and make sure all connectors are fully seated.

i think on that car the pcm needs to be programmed another words you need to take it to the dealer to have data down loaded in to your new pcm
