Removing the injectors just for checking is not recommended. Why?

The "O" rings on each injector will be damaged on removal and unless you replace the "O" rings with new,,,,,,,,,,you just created another problem

There is no sense to attempt to come to a reasonable conclusion if getting into areas when it is not necessary just creates another problem.

 

Update. replaced all vacuum lines map sensor egr valve. Regard me listing to the injectors spraying it was only 2 out of the 6 so replaced them it turned on for a couple of seconds but bogged down and shut off so far going in the right direction getting closer to victory fuel pressure is still at 55psi
