Integra fuel Delivery problem- code 16.

Q.1991 Acura integra LS 5spd non vtec 299,995 miles on original motor FUEL Delivery problem- code 16 obd1 fuel injectors Have replaced: Fuel pump, fuel pres. regulator, pgmfi relay, battery and injectors this weekend. Code 16 still comes up won't let the engine rev over 3000 rpm. Pulled 7.5amp fuse under hood to reset the ecu, problem still exists. Checked all fuses, all good. The pgmfi relay is getting hot, and I'm not sure why. too much voltage? So what I need to know is; Is there anything else I need to check? I can drive the car for 5-6 min. just fine and then won't go over 3000 rpm. Engine light comes on and code 16 flashes on ecu. Just for more info; the guy who owned the car before me (original owner) put a push button start, and a switch that turns the car on. the switch is hooked to the yellow/black and white/black wires on the ignition switch. If he did this wrong, could the voltage going to the pgmfi relay be too little or not enough. Please respond, Thank you.

I already checked/done: changed fuel pump, fuel filter, fuel pres. regulator, pgmfi relay and check all fuses, PLEASE HELP!!!!

More Info required I have read the other concern you had in regards to this same problem.
we need to make sure the system does not have a fault in the ecu.
