Hi all,
I'm having problems with my warm start (doesn't start at all or start but with very low rpms and the engine keeps running 2 or three seconds if I turn it off with the key). Cold start is perfect. Car runs well.
After searching on the web I think it's probably the fuel accumulator. I can check the pressures (I have no way to measure them, unless I get the car to the workshop), change it directly or...
...this fuel regulator have three exits. I'm wondering what is the function of the bottom one. Is it only to return fuel to the tank in case the internal membrane breaks? If this were the case, If I open the line and fuel comes out, would it indicate a faulty accumulator?
Thanks in advance.

Definitely burst diaphragm inside WUR. I had the same issue a year ago.
There is small hose going out form WUR to air filter box and if diaphragm is broken WUR body gets filled with fuel that goes out thru air filter box.

I have already fitted a Zeitronix device with AFR, boost and EGT measuring. So, I need something to tune.
