Did the test running the motor for 1 minute

I went ahead and connected the compressor gauge to one of the injector lines so disconnected nr1 pipe and cranked the motor to see what pressure builds up my gauge has a max of 12bar reading (so it would be stupid i know as these rails have 300 -1600 bar) i cranked the motor for 10 seconds and the gauge only went up to 6bar and stayed there so ran it again for 10 seconds same story ..very very low pressure

Gallon of petrol needed and matches will be a good solution

The injector classification is done problem still persist

Got a gauge to measure the rail pressure gauge only reads to 200bar but on crank it takes a while to build up pressure when the engine is not turning the pressure drops at a steady rate not keeping the rail pressure is a concern ..

It does go to max on this gauge but after 5sec on the starter if you wait 10sec theres no pressure if you crank again it must buil up from 0 pressure again

Pressure going down when the engine is not running is normal. How long is "a while" to build up to 200 bar? Mine takes about one second (or slightly less) of cranking to fire, which is 250 bar. It certainly is not instant. This is normal. If it is 3 or 4 seconds (or more) then there is a problem.

For sure 3 to 5 seconds not 1 or 2
