well a simpler way of checking the connections at the injector without removing anything is backprobe the injector wires at the ECU with the key on, they should all read near 12v, if one is low or reading no voltage then there is a faulty connection or dead injector.
applying a quick sharp intermittent ground should give an audible "tick" from the injector.

hah I gotta remember which oneso f the wires on the ECU are the ones for the injectors
I know the 4 grey and red / diff colors are some of them. hah

Nat,
No need to pull the engine. Even though you still have all the emission and sequential stuff you can still get to all 4 of the injectors with a little effort and patience. I would recommend pulling the UIM off and disconnecting the secondary rail from the LIM. This can be done in 10-15 mins even with all the sequential stuff. Once you have the rail lifted a couple inches up away from the LIM, jumper the FP termninal and one of the GND terminals in the diagnostics box above the positive battery terminal(Black 1"x1" box). Turn the key to on position but dont try to start the car, this will keep the fuel pump running and pressurize the fuel system. The reason to do all of this is to see if one of the secondary injectors are leaking externally all the time. I have had several leaks from cleaned injectors. Start with this before digging in deaper and tackling the primary rail.

If you want to hear the injectors with the car on, a mechanic's stethoscope works very well. You can clearly hear the injectors while the car is running, and hear when the secondarys turn on as well. It takes a little working to get the probe on the injector body, but it isn't too hard.
I'd advise any serious mechanic to have a stethoscope. I've diagnosed many squeaks, ticks, and other things using it.
