How uch fuel pressure are you suppose to have in your car? My gauge reads about 34 PSI and when i get it some gas about 40 or so. IS that right? ANd when i give it almost full throttle like 60 psi

Thanks!

really? that seems kinda low...i don't know though, I have an SPI and I get around 50 at idle and around 40 giving it gas...

uve got a 2.0 right? the injectors are rated at 19lb/hr.

the ecu aims for 37 psi at idle, but can be pushed higher, like 55.

the stock pump can handle up to about 400rwhp.

Your fuel rail pressure should be at 40 psi at all times(acceleration, idle ect)and have a deviation of around +/- 1 psi, under acceleration and deceleration, the pressure at the fuel pump will vary a little with the fuel rail pressure, but the fuel rail pressure is the only important one.

Nemesis ive got a 2.3 with 48lb injectors.(Turbo).
Thanks for the info!

Welman thanks!
