Adaptronic + aromotive fuel pump wireing
In need of some guidance, I blew a main engine fuse last week due to a short in the alternator. iv have fixed all shorts.
But when I blew the fuse my fuel pump stopped working. The ground and power wire from pump relay was wired directly to the ecu. now the pump only works if I use a chassis ground to the fuel pump relay where the ecu ground use to be. but it seems like the fuel pump is always working at 14 v or what ever the car is putting out. isn't it supposed to raise with rpm from 5-14 v? so the pump is not always pumping Max pressure. my car is running extremely rich now at 10.1afr at idle! and I really think it has something to do with this. Could someone just tell me how this pump is supposed to be wired with the adaptronic ecu. I have pinouts but it doesn't tell me anything about what ground to use. The original ground from relay was wired to the (1W- AUX output six) which drives the lights on the dash.. and power is still wired to (3d- AUX Output 5) any advice is greatly appreciated |
