I just bought a impreza that has a ej20g installed. Fun car. Some drivability issues (idle, no top end: most likely due to bad fuel maps?)
Here is my problem. Usually my fuel pressure guage reads 25psi along with an audible fuel pump hum. I drive to work. Everything is fine. Then on my way home, i go to start it and the hum is very low. Almost nonexsitant and the pressure barely above 0psi. It starts with trouble and can idle for a few seconds. Then when I touch the throttle it dies.
I think its my fuel pump. I need to rectify it asap. Any help is appreciated deeply. I am going to pick up a fuel pump tomorrow if that is what it is.
