Need Fuel Pump Power-Feed Help Please;
Posted: Fri Apr 01, 2005 2:04 pm
So, I finally took time out this week to get the GoTech installed...
All's fine and I could actually start it right up with Domingo's pre-loaded 3.0 map...
Problem is that with the AFM disconnected, you don't keep a constant power-feed to the fuel pump... (Alfa has a emergency/security feature that only allows the fuel pump to be powered while you are either cranking the ignition - actuated by cranking the key - after which time the door in the AFM takes over and it's movement actually triggers the "fuel pump feed circuit" within the AFM...)
With the AFM now completely removed, the action of cranking the key actually provides enough fuel to be injected at start-up to run the car for a few seconds, but as soon as you release the key back to the simple "on and running" position, there is no power feed to the fuel pump.
What/where would be the best way/place to jump to the fuel pump from up in the engine bay somewhere - still somewhat actuated and deactivated by the ignition on/off....? (I realize that in the unfortunate event of an accident, the pump would maintain pressure to the system), but for now, that'll have to do....
I still have the stock ECU in there, but it's not hurting anything as it's only function now is to drive the cold-start injector as well as the fuel pump power-on feature at start-up. I wish I knew which of the AFM harness' pins to jump to actuate the fuel pump's "on-running" status, although, I will probably remove all of that crap soon!
Anybody?
Thanks in advance.
