Ive taken the fuel line off an turned the key to prime it and its got plenty of pressure... Flows like a champ! Ive checked for water and have even drained the tank twice... I know its gotta be something simple but that I have just overlooked... Its starting to get to me cause season is about to start up and I cant be without my piece! I just put a new regulator on as well... I will have to run to the local Yamaha shop tomorrow and see what my flow is supposed to be at but other then that Im lost... I will check again from all the info you guys have gave me... Thanks and hopefully I can get this thing going...

 

damn bro.

ok..

flow-ok
spark-ok
timing-ok

so, do an injector test. i think it's 34-37 in the OBD for 1-4.
pull the rail, prime the system with the relay test parameter, then go back to injector test and look for the spray and listen for te pintle snapping open and shut. it'll do it 5 times and each time (as you probably know by now) the FI light will come on when that output is energized.

they've gotta be clogged or you're not getting vacuum to the regulator.. one of those two things i think..

still a bitch to tell over the interwebz tho.

it takens nothing to clog an injector.. its not a complete failure.. gotta be a clog. otherwise you'd get a fail code for the offending injector(s).

its a closed loop monitored output on ALL channels. all the injector and coil pack channels HAVE to feed back thru, as well as all the sensors. if not, it'll fault out on an open circuit code.

 

Cool cool Ill have to run down to the shop and check this stuff out... Thanks for the info and Ill keep you posted on whats up... Again thanks for all the help!

 

worst case, you can send the injectors out for a flow mapping and ultrasonic leaning.. places like RC injectors will do that, unless you got a bangin local engine builder and tune shop near by. might be cheaper than getting new ****.
that is.. IF thats the problem..

 

YEa just looking at fuel flow it might look good. You definitely need to measure it. a matter of 2 oz. in 10 seconds is enough to mess up the way the bike runs. I wouldn't guess clogged injectors if it was just running and now isn't with a different pump and tank......

 

Ok... Will give a look at both those ideas... Also when I got the bike it had a PCIII, so should I hook it back up and send a stock map back to the ecu? I dont even have a clue what map its running off of but I think a stock map mite just mite help to??? Let me know thanks!

 

if the power commander isnt connected it is running off the stock map. power commanders dont change the ecu programming, once its removed its running off the stock ecu map.

 

Cool just wasnt sure...

 

right (as usual).. as well, if the PC is hooked up, all you have to do is zero all the fuel parameters across the board. that'll esentially give you stock fueling, since it's neither adding nor subtrating fuel at that point.

if you wanna tune it yourself, your best bet is a wideband with logging capabilities if you don't wanna pay a retarded dyno fee.. i'll be getting a dyno and wideband within the next year or so i think, so when i do, i'll be posting up how-to's on tuning.. it's easier than ya think, but then again, the software dynojet supplies for their certified tuning centers does most of the smoothing and damn near all the work. it practically makes the map based off the dips in power from the dyno chart.

almost wonder if someone installed the PC to get the thing to run right.. or if them removing it mighta fucked something up if they didn't know what to do? Hmm.

 

Well at last the bike is running!!! Had a vapor lock! Cleaned the injectors and thru some air thru all the lines and checked a few things and she fired right up... I will be back and riding before spring and I cant say thanks enough for everybodys help and input... Thanks again!

 

grats bro. hope you have fun on that r6. i read the whole thread then i got to where u said it was running and almost kicked myself lol. vappor lock y the hell didnt anyone think of that

 

the injectors should have power to them on one side of the connector ALL the time when the key is on and the ignition circuit is hot/on.

if that is cool, then you need to put an noid light in the connector and see if the ECU is grounding the circuit to each injector. and with all cylinders not getting fuel, it's one common problem.

the crank signal runs the ecu to provide fuel via the pump, the ecu also triggers the coils (primary/secondary coil windings) to provide spark. if you got spark and no fuel...seem like you got ur answer man.

gotta check the injector harness and plug. ECU also....seen some fart out on the injector circuits all together.....good that you got it slimmed down to that now tho. good luck, hope you get it going again.

 

good deal man!! normally when i think of vapor lock, i think along the lines of hydrolock, in which case the motor won't turn at all..lol

right on. good **** man

 

Yep! Thanks guys for all your input... I have a few more cosmetic things to fix then Im up and going again... Ill post up some pics once I get done! Again thanks for filling me in on possible problems it could have been...

 

cool bro
