the car is not getting fuel to the injectors, fuel is in rails, getting spark on 1997 Mercedes-Benz E420

Fuel pump was replaced, after I ran out of gas, was told it was weak, replaced that, now its getting the fuel no problem up to the rails, and getting spark, the test was done capping off a few injectors to see if test light goes on to see if present, no fuel getting to injectors, was running perfect before all this

use a noid light to see if your injectors are working
just not getting fuel to the injectors, when a few were capped with the noid light it was not lighting, same for all injectors, they were not firing, was told they were not getting the fuel to there, so not firing,... read previous if needed please thankyou
