yes, I check all the coils, they are all good and dont seem to have a short in them, I guess the plugs are fould or something idk really? Idk whats going on, but il b getting new plugs and going from there i guess.

 

When I checked the spark plug i just pulled the coil out and tested a spark plug I had laying around for the bike ( i know very lazy) At first though the spark plugs did work, but I guess they just got fould or burnt out or something.idk.

 

Fouled with gas? Hard to do if the injectors aren't working...

 

IDK, When I took my injectors out and everything to test them against a rag. THere was no gas. Since then though I played with wires and a few grounds, can seafoam dirty up plugs? i know that sounds ironic.

 

from the sound of it, he has pressure, but gas isn't dropping and a code 19. that's a by-the-book ignition plus regulator issue. So stop all this craziness for a second. go back and look at the pictures that i took the trouble of scanning.

1st page, it says test for Ground... turn your bike off.. disconnect the sensor. look for White/Yellow wire from the connector. With your multi-meter... touch one end to the White/Yellow... touch the other end to the engine or the frame. you should get 0.0v. Read the procedure...it says throughout the connection/wire to insure continuity. this is to make sure you dont have a bad ground.. which causes an electrical short. While you're at it, clean the connectors with some sort of electronic spray. so make sure this is goood.. before you move on to step two.


2nd page. test for voltage. it sounded like you did. and you got a bad voltage reading of 0.4v when it should be at least 0.7v. So what this means is that.. if you have good grounding, but the reading is off.. it's either your Sensor or ECM.....assuming your multimeter is not a piece of crap.

The next step is to test your ECM.

so before you go tearing your whole bike a part and dumping injector cleaner into your gas. try the steps recommended by the service manual first. From here, you can move on. else... you're running around the problem, which is unproductive and will cost you more money in the end. but who knows, you might get lucky.

 

It's almost at that point to start from square one with rechecking spark, air, and fuel (pressure and pulse). Get good plugs in it and go from there. This really isn't that hard...but the info has all changed. Mnguyen84 is right about testing that stuff, but please verify that its missing that signal first.

 

Ok, this is weird, I just changed out my new spark plugs with my old ones. It runs!! Im not sure what went on, but Im pretty pleased with it running, just as strong as ever. I know non of this makes sense now.

 

That's good news. I think a connection, ground or otherwise, got wiggled in all your testing and is currently making a good contact. Just a hunch....

Don't ride too far from home right off, in case it quits again.

 

Seafoam finally kicked in
