Crank the engine for 5 seconds while observing the fuel pressure you should see a minimum of 1050 bar, if the pressure exceeds 1050 bar refit all the connectors and remove the leak off bottles.
Start the engine and warm up then refit the bottles, run the engine for 1 minute and check the bottles all the amounts should be the same, if any bottle is significantly higher this will need the injector replaced. If the amounts are all similar run the engine for for minutes after this measure the fuel in the bottles. Use the lowest amount and times this by 1.4 this gives the maximum volume allowed if any injector exceeds this try to input the correction value and retest also make sure the engine management software is up to date.
If on the 5 second crank the fuel pressure is lower than 1050 bar check the amount of fuel in the tubes to the bottles,Do one or more clear plastic hoses contain no fuel and one or more have a recorded value greater than 20 cm in length?
If yes Install new fuel injectors for those injectors with recorded values of greater than 20 cm. Retest Do all of the clear plastic hoses contain fuel? Yes assemble the vehicle. test the system for normal operation. No install new fuel injectors for those injectors with no fuel present in the clear plastic hoses.
If after the original test the answer is no then do all of the clear plastic hoses contain fuel and one or more have a recorded value greater than 20 cm in length? Yes install new fuel injectors for recorded values greater than 20 cm. If the answer is no, Are all of the recorded values less than 20 cm and one or more clear plastic hoses contain no fuel? Yes install new fuel injectors for those injectors with no fuel contained within the clear plastic hose. If no install a new fuel pump.
