    Honda 225 coils

    Would like to get some input on resistance readings on my coils. On 4 out of the 6 the readings are roughly about the same 4.5 ohms. But on 2 of them the reading is about 2 ohms . Is it possible that they could be bad. Thanks for any imput

    IAB vacuum

    The IAB valves are completely functional. I have had it apart several times . The only thing that I haven’t replaced is the IAB solenoid, but I tested it . When I connect it to the 2pin connector you cannot hear it click. When I put 12 volts to directly it sounds fine , and it checks to the...

    No apology needed. But I still have the issue of the #9 pin on the ECU having no continuity to ground.

    IAB vacuum

    I checked everything. I ran all of these tests yesterday. I followed your instructions as the manual and tested again. I figured it can’t hurt. I have the same results. #5 fuse is good, 12 Volts from Y/BL to ground. No continuity between #2 pin and ground. I pulled the 26 pin connector pin and...

    IAB vacuum

    FYI . When I hook the solenoid to its 2 pin connector and energize it you cannot hear the check valve open. I only hear it when I put 12 volts directly to the terminals on the solenoid. Also if I check the Y/BK wire on the 2 pin and a ground I Have 12 volts

    IAB vacuum

    Ok Chawk man. I checked everything. What I found was that there is no continuity between the black pin on the 2 pin harness to ground .so what the book says is to replace the ECM. I checked the IAB solenoid and it checks out fine. It has continuity , and when 12 volts is applied you can hear...

    IAB vacuum

    I have an issue . Honda 225 IAB vacuum is opening as soon as the engine is started. I’m wondering if it could be the IAB solenoid. Any help would be greatly appreciated. Thanks, Gary

    Hond 225 3950 max rpm

    Ok . This is what I found so far. The IAB is opening at idle, which is really confusing me. I have vacuum from the line with the check valve which I think is correct. I assume the check valve is supposed to make vacuum in the vacuum tank. When I shut the engine down I pulled one hose off the...

    Hond 225 3950 max rpm

    Wow! That is alot for my little brain to process this early in the morning. The check valve you are talking about, is that the one that comes from the fuel regulator? I will follow as directed, and keep you posted. Thanks again , Gary
