RE: Injectors arent closing? Help me - 6/10/2008 7:46:46 AM    JimBlake   Posts: 3272 Joined: 5/31/2006 Status: offline 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) < Message edited by JimBlake -- 6/10/2008 7:48:38 AM > _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to HondaPhyco) Post #: 34

RE: I need imediate help please - 6/10/2008 5:59:29 PM    HondaPhyco Posts: 127 Joined: 12/2/2007 Status: offline 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. _____________________________ -1996 F22 2.2L Honda Accord LX -Street Flow Air Intake Kit -JDM Projector lens. 20% Tints, from THE TINT SHOP!

RE: I need imediate help please - 6/10/2008 9:01:52 PM    JimBlake   Posts: 3272 Joined: 5/31/2006 Status: offline OK I''m not real sure what you tested. 1 - Unplug all the wiring harnesses from the ECU 2 - Set the meter so it beeps when you touch the leads together 3 - Touch one lead to the non-red/black wire at injector, touch other lead to a good ground Then the meter should NOT beep because that wire isn''t supposed to be hooked up to ANYTHING. _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to HondaPhyco) Post #: 36

RE: Injectors arent closing? Help me - 6/11/2008 4:49:30 AM    HondaPhyco Posts: 127 Joined: 12/2/2007 Status: offline ok unplugged everything from ecu no voltage on the non red and blak side and 12 volts on the other side. but it didnt beep. but meter shows voltage. what else? _____________________________ -1996 F22 2.2L Honda Accord LX -Street Flow Air Intake Kit -JDM Projector lens. 20% Tints, from THE TINT SHOP!

RE: Injectors arent closing? Help me - 6/11/2008 12:25:56 PM    PAhonda   Posts: 1348 Joined: 9/22/2006 Status: offline 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. _____________________________ 1995 Accord EX MT (in reply to HondaPhyco) Post #: 40

For testing the red/black wires the meter should be on DC Volts.  It should read battery voltage. < Message edited by JimBlake -- 6/11/2008 1:11:24 PM > _____________________________ '03 Accord & '07 Civic '01 Saab 9³ & '05 9²x (in reply to PAhonda) Post #: 41

RE: I need imediate help please - 6/11/2008 8:43:54 PM    HondaPhyco Posts: 127 Joined: 12/2/2007 Status: offline You may read the FAQ for more basic troubleshooting, otherwise just follow this troubleshooting flow chart before performing the main relay bench test. The main relay typically fails in three ways.  One is when there is only 1 click after turning the key and the fuel pump won''t run. The other is when the check engine light is steady on (no clicks) and the fuel pump won''t run. The third, most uncommon, is when the check engine light goes on and off normally (click on and click off normally) and the fuel pump won''t run. This symptom needs to be tested in order to rule out the possibility of a dead fuel pump or a bad power supply that is too low to run the fuel pump. Basically, if the fuel pump is running the main relay is fine.  If there are no click but the harness connector power supply is good, (how to test below) then the main relay is most often bad. The troubleshooting flowchart (which uses your senses) below is an accurate diagnose if your symptoms follow the flow of the chart. I only get one click!!!!!!!!!!????? _____________________________ -1996 F22 2.2L Honda Accord LX -Street Flow Air Intake Kit -JDM Projector lens. 20% Tints, from THE TINT SHOP!
