Have you cleaned the fuel distributor - especially the fuel plunger rod and matching cavity?
Have you verified the CIS injector flow pattern?
Does this happen with full or empty fuel load?
Have you cleaned the siphon screen on the fuel tank?

Ivan,
Install the CIS gauge and measure:
- CCP (cold control pressure) electrical plug to WUR disconnected.
- Check the system pressure.
- Install the WUR electric plug and start the motor.
Have you done a smoke test to verify the absence of unmetered air going into the system? I would be curious to know how the CSV and fuel injectors delivered fuel looks like during the initial start stage. You want a mist-like V patterns and not a jet-like flow spray pattern. Keep us posted. Thanks.
