I wouldn't replace them yet, but would have them on hand. I would check their connections for corrosion first, both at the injector plug and the other end (not sure what that is).
I'll do it today, thank youAbout 13-14 ohms resistance. About one amp current. Oxidation could be the problem. You can remove the the ECM connector, turn key on, and in current measurement mode check for current. Testing for current means changing your positive test lead and using the 10 amp jack. There is a schematic diagram of the ECM cap with info and color code. How to Step by Step 1800
I'd bet thats the vampire-clipped gray wire. Those eventually cut through the wiring and cause a bunch of problems. It should be soldered.Pics might help with some diagnosing. Vince, didn't you have a fuel manager on it, too?
Unplugging it will not erase the code. There is a procedure to do that. You can find it on the forum.Do you think unplugging the ecm and plugging it back in would reset the fi code?
Yes, the DMM gives a reading of 0.3-0.4 when touching the leads. It's curious how I was getting 24-25 ohms the first day, then yesterday 14; and the fi code cleared. So, I'm thinking I should go ahead and replace the injectors. Now the other development is, and I feel a little foolish, this bike already had a power commander installed prior to me installing the fi2000. I looked up the instructions for installing a pc while investigating the gray wire, and I found that the previous owner hid the pc module inside the battery box; so it was there the whole time. So I'm removing the vampire clips that were there for the alarm and the fi2000 and using liquid black tape on the wires. I'm learning as I go, obviously, so I hope I can get a clear understanding of what happened here and why. I've been looking for any related how to step by steps, nothing so far.Red/Yellow is the TPS wire that feeds variable voltage to the ECM.
The Gray wire goes to the FI2000 and to Power Commander, which ever is used.
When you test for Ohms do you short your test leads together to see what resistance valve shows up?
Most low coast DMM will not give a zero. I have a few el-cheapo ones and they get to 0.4 to 0.6 ohms with new battery.
If the ECM sees a good value it will disappear.
Have you read anything in the How to Step by Step 1800 board?
That's an interesting idea, I'll check it out. I thought because of how old they are, maybe changing them would be advisable; do they normally hold up ? My bike has a little over 30k miles.Can you remove the fuel rail and injectors as a unit and observe the injector spray while cranking??
I remember one case where a blob of crap was on the fine mesh injector screen.
Some other guys mentioned having a diesel shop check injectors years ago.
They should last tens of thousands of miles. Much longer than you have. Some have probably never changed them.That's an interesting idea, I'll check it out. I thought because of how old they are, maybe changing them would be advisable; do they normally hold up ? My bike has a little over 30k miles.
