With the key in the ACC position, second turn of the key, I push in the brake pedal the pump primes. I hit the hazards, the pump primes. Use the turn signal, pump primes. Obviously something is definitely wrong.
The thing is I havent touched my fuel pump in like 2 years. During my build I didnt touch the fuel pump at all. The only wiring I touched was having to hook up gauges and hooking up the EMS. I did do repinning on the EMS for MAP and IAT sensors. I saw that on the EMS there is a Fuel pump relay pin but never had to touch it and never did.
I connected my old ECU and the problem did not occur. So its only happening when i hook up the EMS.
Anyone run into this problem and help me figure why my Fuel pump primes when an accessory unit is used (i.e. brake pedal, hazards, turn signal, and radio when turned on.)

Check your battery are wiring, i.e. your engine swap wiring and make sure that you still have the ECCS Relay WIRE contiguous on both sides
It is a RED thin wire with a BLACK STRIPE
