Trying To Find The Easiest Way To Sus Out Fuel Problem.

[ricknismo]

You guys know an easy and cheap way to work out which fuel issue is the one causing the problem...ie

Fuel pump or injectors or regulator.

Rather than rip each out and have them checked???

What is the problem?

Fuel pressure gauge will tell you if it's injectors or pump/regulator problem.

Blocking the fuel return from the regulator will tell you if its pump or regulator

Regulator problems tend to be there all the time at all rpms's and power outputs

Pump problems get worse (lean out) as the rpm increaes

For injector sizing problems, simply look at the duration.

Yeah, kinda need to know what the problem is first

[ricknismo]

In my mates car as you build up revs, the duty cycle of the injectors goes up conciderably..ie normally at that boost level about 60%...his goes to 95% anywhere above 5000rpm.

pressure gauge, see what its doing

my bet fuel pump dead, or reg next, but reg has a massive fuel cloud generally associated
