I was having trouble with the car making low power, low RPM and backfiring. Car would idle fine.
I put a fuel pressure guage in the fuel line at the rear of the fuel rail.
30 psi at idle but only 15-20 psi at 2000 RPM. I changed the fuel pump. I now get 30 psi at 850 rpm idle, 30 psi at 1000 rpm, 30 psi at 2000 rpm and 28 psi at 3000 rpm.
I am trying to find out what the correct system pressure is.
Anyone know what pressure the regulator is supposed to be set at?
