Not sure I fully understand your exotic use of the language but if the pump runs when the AFM flap is pushed in the fuel pump relay/circuit *has* to be working. You may want to think about how pushing the flap in differs from when the engine is running and pulling it in. And I think you and the other guy from Queens should team up. Think of the possibilities...

u know its kind of funny that they dudes that think they now everything and the ones that have nothing better to do with their time, so its either ur a dick or just a guy with too much time on his hands, so its either u help or just ignore my trend. If i open the flap its direct power to the fuel pump and the cor is suppose to act like a switch in between, so if its not getting and power with the power on ignition then something is wrong...its either main efi, cor or pump relay.....but now i notice that i get no oil pressure on the gage so i am wondering and i know the nerd will problem no this, but if i get no oil pressure, does the ecu think that the car was in a accident and shut off the power to the cor?
Ok, you win. It's possible the ECU thinks the car was in an accident and shut off the COR. In doing so it also shut off the auxiliary electric priming pump below the center valve cover. That in turn will prevent ignition because, you know, a lack of oil pressure would be bad. To reset the COR you'll need to locate the G switch (accelerometer) and jumper pins 29 and 54 for 3 minutes with the EFI fuse removed. It's above the steering column next to the wiper control relay. If you have a power driver's seat it must be all the way forward when doing this...

sorry, how exactly am i suppose to reset the g-switch? and isn't the wiper control relay on the passenger side of the car?

I love all your sounds.
I think I actually reset it by accident one time by slamming the passenger door too hard, but my car is N/A, so it may not apply to you.tsparks01;1258323 said:

i am not sure of what exactly what i need to do here, you want me to find the g switch and jump the pins 29 and 54 for 3 min? but what does it look like and how do i jump it exactly?
