LaGrasta Posted August 22, 2022 Author Share Posted August 22, 2022 not sure about the click (ill have to test this), but the pump whirs. If I disconnect the fuel line at the injector, the pump PUMPS! 1 Link to comment Share on other sites More sharing options...

Do a voltage test at the battery: 1) After about 6 hours or so with Ignition off. 2) Ignition/lights on for a couple minutes. 3) WHILE cranking.

Lucky Phil Posted August 22, 2022 Share Posted August 22, 2022 Do you have the injector plugs correctly installed? they take quite a lot of "push" sometimes to overcome the locking clip on the connector. The pump, injectors and coils feed from then same relay so if one works they all should. Is the ECU correctly grounded? Phil 1 Link to comment Share on other sites More sharing options...
gstallons Posted August 23, 2022 Share Posted August 23, 2022 You can get s "noid light" to plug into the injector harness . Crank the engine and it will flash when the injector is triggered . 2 Link to comment Share on other sites More sharing options...
LaGrasta Posted August 23, 2022 Author Share Posted August 23, 2022 yes, the relays click, and the pump whirls; confirmed last night. I like @gstaallons noid light idea. I may check into that as it would be nice to confirm it's working. I believe the injectors aren't cleaned properly. The thing is, even if they aren't spraying, they are at least squirting, it should still fire, and it's not. @LuckyPhil, they are installed correct, securely locked in. As for being properly grounded, I do have an understanding off this importance. I have not checked this, but I believe it is all stock so it should be correct. Laughable I know, but I'll still mention this, the owner said it ran when he parked it. 1 Link to comment Share on other sites More sharing options...

gstallons Posted August 24, 2022 Share Posted August 24, 2022 When you are working on this , you want 12v on one side of the harness and the other side of the harness is triggered (grounded) to cause the injector to activate . This takes place one time every other stroke of the c/shaft . 1 Link to comment Share on other sites More sharing options...

LaGrasta Posted August 25, 2022 Author Share Posted August 25, 2022 I bought it about two weeks ago, Amazon. Because it was purchased online, no returns! I put it on a 2amp trickle last night, this morning it reads 12.69. I must say though, the bike turns hard and fast, no problem. This is not the reason it's not lighting on gas. The injectors will be pulled again this weekend, I'll clean them and if no success, I'll get them cleaned or replaced altogether. 1 Link to comment Share on other sites More sharing options...
LaGrasta Posted August 29, 2022 Author Share Posted August 29, 2022 Pulled the injectors this past weekend, cleaned them again. Same results, strong, single stream. As my original thread was questioning, is this correct? It seems no one knows if it should be a spray or a squirt. My plan now is to be sure the leads are receiving signals. I suspect maybe not, as I noticed the throttle bodies appear dry. Maybe they could have dried by the time I got in there, but I see no signs of dry fuel. I don't own the injector noid mentioned. Before buying a set, any other way to check? Maybe with an ohm or volt meter? Link to comment Share on other sites More sharing options...

Before buying a set, any other way to check? Maybe with an ohm or volt meter? Until someone pulls a real-life example to present, I'll say that there is *no* case in which an injector should have a steady stream. The entire fuel mixing scheme demands atomization, whether gasoline or diesel. It sounds like the pintles are stuck wide open, which makes no sense unless the computer is demanding it, and not possible on a bench without a signal connection. Here's a video showing how to test the signal to the injectors using a 'noid' light- back in the early days of EFI we made our own with a 3- or 6- volt dc light bulb, soldering wires to it to shove into the harness plug. Edit; sorry I missed the previous mention of noid lights. You can simply make your own from a 6v taillamp bulb or flashlight bulb and some thin wire. 1 1 Link to comment Share on other sites More sharing options...

If it looks like the picture and they say that's good, it's good. 1 Link to comment Share on other sites More sharing options...
