the problem i am having is my fuel pump isnt priming....it stoped priming before i tryed a new base map..i figured it might of been my old map that caused it to stop..so then after the new base map it didnt fix it. so i straight wired the pump and it works.....so then i used a volt meter and checked the plug that goes into the pump and there is no power getting to it...i checked all the known fusses that would control the pump. is there a "special" fuse that i might need to check...or would it be the aem causing it????i have searched through 35 pages of "fuel pump not priming"...any body have any ideas????? please help im getting so frustrated......

 

fuel pump prime is not required, the stock ecu doesn't do it.

it should be a setting in the cal post it or send it bbyevo@hotmail.com

 

ill send it to you...thanks man

 

also if i switch between maps it still doesnt prime...it doesnt matter what map im using....

 

I have seen this once.
I was on my friends car.
His fuel pump primed sometimes and sometimes it didnt.
It was solved by uploading the 1.19 firmware again.

 

i just strait wired the pump while it was in the car and it started fine...soooo its either the ems program or a fuse/relay( i checked all that i know.....does any one know were to find the wiring scimatic of the fuel pump

 

im about to try and upload that software agian

 

alright i pulled the pins for the ecu and pin number 22 has voltage coming from it....here is the diagram i went by..... http://www.roadraceengineering.com/e...-ecuwiring.htm

let em know what yall think......

 

new thread started found diff prob........thanks all
