So you have fuel pressure at the rails?
When you take the inlet manifold off and crank there is no fuel coming out of the injectors?
Do you have the fuel lines the right way round? FPR is on the return side, that's a common mistake.

Re: KLZE runs fine then dies and have no fuel plz help!!
fuel lines are correctly mounted i have fuel pressure at my rail
but my spark plugs are dry
i think that my injectors wont open
if i detach my fuel relais the car starts but runs extremly rough and when i touch the gas i dies
i mesured also the vaf
open 200 ohm
half way around 740
and deeper in it decrease

Re: KLZE runs fine then dies and have no fuel plz help!!
Does B+ exist at the fuel pump terminal with the ignition on? (not jumped at the diagnostic box) If NO, it's the fuel pump relay.
Is there fuel injector operation sound when cranking? If YES, and the fuel pressure is good at the rail, it's probably the ECU. If NO...
Does B+ exist at the correct terminal of the ECU with the ignition on? If YES check the voltages at the ECU injector terminals. If voltages are low, the ECU is bad. If NO, you're losing battery power somewhere after the Fuel Inj relay.
Check that you didn't blow the Fuel Inj relay. I've done it.

Re: KLZE runs fine then dies and have no fuel plz help!!
It means do you have Battery Positive power (12V) at that point? You would measure it with a multimeter or voltmeter.
