Thread: Fuel pump primes with headlights...

from the aem software you want to select configure out puts. this will allow you to take another unused out put and make it do what you want. you have switched ground and switched power. iirc the fuel pump is at hs11 right now. so you will clip the factory wire and move it to another out put on the aem and then configure the out put to be a fuel pump. if you read the embedded instructions for the aem unit you are using it gives you a wire diagram and a list of outputs that can be configured. it also tells you if its pw,hs, or gnd.

Excellent. I gotta swap in another pump since we think mine took a dump. No matter how much fuel we tried adding, the wideband read lean as all hell. I'll try to play with it before work. If not tomorrow I will get it figured out. Thanks a lot for the help man!

sure thats not a regulator problem? (wideband going lean no matter the amount of fuel added)

regulator problem or fuel map/injector setup problem. It could be a lot of things really. He needs to verify fuel pressure when in boost with a cyberdyne or some other brand electronic fuel pressure gauge if everything else is ruled out.
