fuel injector query

I took my injectors out and tied them off to the fuel rail to watch the spray pattern. I was alone, so to make spray, I left the key on and jumped the solenoid. My question is that the all sprayed at the same time. Is this normal, they aren't sequential? Thanks in advance Warren

if you just tied it off, then it should be normal.

if its older its group fire. fires four at a time. and when you first turn the key on they all fire for starting.

Thanks mike. That also probably explains why my scanning tool won't go into the cylinder balance test.
