1 fuel pressure

ch3ecm fuel pump and fuel pressure regulator

2 faulty ecu or wiring to injectors

3 glogged injectors (I doubt it though since all of them are messed up)

Get a 9 volt battery and jump the leads on the injector and see if you can hear it click. If it clicks, than the problem is electrical.

I checked them by taking all the injectors out still connected to the fuel rail, cranked it for about two seconds, and nothing came out...

yea, I can hear the fuel pump...no, I havnt checked the resistive values(not really sure how too)...
And for the record, this is a 92 Integra LS motor in a 91 Crx SI...I had to make the obd-0 to obd-1 conversion...so there might be some wrong connections on the ECU plugs...what things should I check directly on the ECU plug that would relate to my fuel problem?

I had the same problem with 3 of my cylinders/injectors. Try this.
