any trick remove injectors

Any tricks to remove the injectors . can they even be unplugged without removing stuff first

It's a tight place, but you should be able to remove them alone.
Get new injector seals and install them even if the old ones look good!

And don't forget to bleed the fuel pressure

I pulled one out and changed a leaking inlet oring now no leak but engine is only running on 5 cyl Could air need bleeding?

Did you check the connection?
If you have a technician stethoscope, you can hear it clicking. If you don't have one... 3$ at Harbor freight!

Could be a piece of dirt that entered the injector and plugged it.

Since it's not a completely close system (there's flow), no need to bleed the air, it's pushed out in a few seconds.

When the connection is in tight places, one of the connector pins can be pushed out a bit because there's no room to push it dead straight, and make bad contact. I'll check that first.

Make sure that it's the cylinder on which you remove the injector than is not firing, coincidence can happen

I can hear it clicking when holding a long screwdriver to it like a stethoscope. There was a small flat spot broken from the inlet o ring . I,m afraid its ended up down inside I,m going to pull the 3 from the side with the air filter and send them out for cleaning and flow testing If it fixes it great . I will consider digging the other 3 out depending on the flow test results before/after

Great, I hope you can figure out the solution

Before you spend more money - ask about the upgraded injectors. At some stage the # of holes was increased and that gives a much better 'cone'.bInexpensive generic upgrades are available. The Bosch filters,O rings and retainers all are available inexpensively
I found it very useful to make a test rig to check flow before installing them

I looked at the end of the leaking one removed and it has 4 holes suggesting it already has the updated injectors. I didn,t bother to note the part number though as I wasn,t expecting a running problem upon reassembly.
