I am installing an 1UZ VVTi but have troubles with the fuel pump relay's control.
I like to use the FPR function, where the ECU grounds the Fuel pump relay by to start/cut the fuel pump. (I skip MREL function)
I wire the pin 4 in the 22 pins' connector to relay coil , but ECU is no grounding that pin. If I ground it, it starts.
Any idea guys?
