I need imediate help please
No, look for short-to-ground before getting a new ECU. If the real problem is a short in the wiring harness, a new ECU won't fix it. TEST stuff, to figure out what's wrong.
Unplug harnesses from ECU.
Unplug each injector & measure continuity from non-red/black wire to ground. (Yes, you'll need a meter)

ok jim...i bought the meter. i measured the voltage and got 25 all across. ok this meter has a setting that when current flows it makes a steady noise. ok well i did test the non black and red side and the sound went away after two seconds meaning the ecu is fine? it was the same forall four injector wires. as for the other side on voltage at on position but after key went off the metershowed climbing voltage untill steady. anything seemed wrong here. and will a short make the fuel pump run that long? according to PaHonda it could be the ecu or the relay. so give me your opinion or more things to test. thank you.
OK I'm not real sure what you tested.
1 - Unplug allthe wiring harnesses from the ECU
2 - Set the meter so it beeps when you touch the leads together
3 - Touch one lead tothe non-red/black wire at injector, touch other lead to a good ground
Thenthe metershould NOTbeep because that wire isn't supposed to be hooked up to ANYTHING.

From your earlier post, I really don't get the voltage climbing up to 25...?? That's bizzare so I suspect you had the meter set for something other than DC Volts.
It should read 12V on the red/blk wire, not 25V.
We do not want you to check for voltage on the non-red/blk wire (what color are those wires anyway?). You want to check for continuity on the non red/blk wire.
Tell me what brand of volt meter you got, and I will look up the symbol that you need to switch your volt meter to.
