k guys, did some searching and havent come up with an answer, basically i need some more advanced diagnosis options.
just finishing my 92 tsi awd build, and i am having some issues with the fuel pump not turning on in the proper order. ive gone though THIS thread, and the only circuit thats not functioning is pin 9 on the relay. i have proper voltage on all other pins, and can jump the fuel pump at my rewire in the back and the car will run.
i have an aeromotive 340 stealth pump, it is rewired, and i did swap out the abs fusible link pack where the battery used to be, for a non-abs one.
the 4 pin connector back at the fuel pump gets the following readings when turning the key:
YL/GR- 12.6v with key on, MPI relay in or out
BLK- 0v "
YL- 6v "
BLK/WHT- .09-.10v "
the BLK/WHT wire doesnt change if i turn the key to the start position with clutch depressed (car cranks over).
any insight would be helpful, just want the fuel pump circuit to work like its sposed to instead of bypassing it or rigging it otherwise. i will upload some pics of the fusible link and MPI pins ive tested
