Yes, 180 PSI is for ALL of them, cylinder #1 included.

I tested the injector signal with the connector unplugged because I have no test jig to test it out "in-circuit".

Yes, I did the tune-up in response to that problem. I've replaced everything in the ignition system: plugs, wires, rotor, cap ect. I tested the cylinder #1 plug by putting it on the metal part of the engine block and the spark was identical to the other cylinders: big & crisp.

I'll bring my oscilloscope in the garage saturday and I'll test the injector "in-circuit" in order to determine what is the problem, I'm suspecting now the ECU not "pushing" enough current to energize that injector. I'm not raving too much to do that test because I'll have to splice-out the injectors wires to be able to "read" the signal at least on 2 of them. Yuck

keep you posted
