Message	Strange problem here... My fuel pump does not build pressure until 4,100rpm. I have around 45psi until 4,100 and then it jump to 60psi. I tried to bypass the fuel pump control unit and pump runs fine. In this way pump builds pressure from idle. Just for info: boost is 9psi at 3,300rpm and 14+ psi at around 4,000rpm.
