so when i have my eccs relay wired up correctly my ecu gets no power and the fuel pump doesnt prime. this started happening after i replaced my engine wiring harness with a brand new one from wiring specialties. i have talked with yuri and he had told me the wiring for the eccs was mixed up. so i corrected it and still nothing. i can get power to the ecu by just putting one of the red hot wires to the red/black ecu wire but i want to get this fixed correctly, any ideas? btw if i do put power straight to the ecu my fuel pump doesnt stop priming so i suspect i have damaged the ecu and will have another one to test in the next day or two.

any help is appreciated
i want to get my car back on the road already.....
