43.5 psi would be nominal. You can go as low as 38 psi and still remain within the ballpark. I run an adjustable fuel pressure regulator running close to 50 psi with stock 24 lb/hr injectors. I am not suggesting you do this using the stock ECM though. I am using MegaSquirt II version 3 for fuel management so I can handle the increased fuel delivery. Shoot for 40-44 psi with the stock ECM. Hope this helps!

Why does my 1991 corvette idles then stalls touch gas stalls?
it could be the tps sensor, map sensor, idle air control vavle, in jection problem, or something simple as a fuel fiter dirty, check the fuel pressure with a fuel pressure guage that you can pick up at any auto parts store
Where is the pressure test port on the fuel on 99 Chevy suburban?
under hood, on fuel rail which is connected to each fuel injector there should be a valve that looks like a tire valve. That is the shrader valve, test fuel pressure there.
What do i check on 1985 grand marquis if turns over but wont start have power to coil but no spark?
i am a land rover master tech,the first thing to do is make shure you have a good battery.test the fuel pressure and if there is no fuel pressure the fuel pump will take out the crank sensor leavig vehicle with no spark. so if you have good fuel pressure and no spark it sound like your crank sensor is bad.common problem. i hope i was able to help you.
Where is the fuel pressure regulater on a 2000 Grand Prix GTP?
it is mounted to the fuel injector rail where the high pressure comes from fuel pump and pressure is at a set psi per engine there is also a vacuum hose that raises the fuel pressure about 8-10 psi when load is applied on motor to give a boost of power
Buick 3.3 v-6 will not start good fuel pressure and spark will start with starting fluid?
Fuel pressure should be around 40. If the injectors are not getting power it will not start. Start with a crank sensor first.
