Hook up fuel pressure gauge to verify system pressure and control pressure. This will tell you if the problem is with the WUR and/or fuel pumps. For Engine type 930/66 (not positive if this is what you have, but values should be close) system pressure should test within 6.0-6.7 bar. Cold control pressure will vary depending upon ambient temps...at 20 celcius, it should be around 1.25-1.50bar. Warm control pressure should be 3.65 bar +/- 0.2

Your problem may also be ignition related or an intake leak.
