I got ahold of a pretty beat up 03 R6 for cheap and have been dumping some money into it slowly putting it back together... Prior to me getting ahold of it, it had a honda tank speaker wired into the fuel pump... I replaced with stock R6 tank and fuel pump and threw a new complete harness on it... The bike ran before I fixed its imprefections... lol But now that I have made these changes and fixed them I cant get the bike to fire... It cranks but just wont turn... I checked and all plugs are firing and in good condition... I sprayed starting fluid over the air box and it fired up... So its like im getting no fuel to the injectors... I didnt know if anybody could help me with what I need to check next... Thanks and all help would be great!

 

is the fuel pump kicking on?

i think mine would start without the gauges, but i cant remember (hondas wont unless you jump them).

 

Yeah the pump kicks on!

Its a Yamaha R6 but had a honda tank wired up to the harness replaced the harness, tank, and pump with the OEM 2003 parts and now cant get it to start...

 

are the gauges hooked up? and check the controls on the clip-ons.

 

Gauges are hooked up... I ran the diagnostics thru the gauges... Clipons and all controls are fine and working right... Im just getting no fuel to the injectors... When I sprayed that starting fluid over the air box it fired right up... Its just getting no fuel... And I dont seem to know why...

 

Any Ideas????

 

how is your injector harness? did you replace it too?

 

No havent replaced it... Is there anyway to test it? Im getting power to it so I dont know what else to check...

 

need to break out the trusty volt meter and see if the injectors are gettin any signial

 

will be doing that!

 

will be doing that!

 

try gettin a set of noid lights and test the connectors to the fuel injectors to see if they are even getting power...

 

So I tested the injectors with a noid light and they are getting power and everything seems to be ok... Still will crank but no fire... Im replacing the fuel pressure regulator and put new plugs on... But if by any chance that doesn't work any ideas?

 

fuel, spark, air. start with the fuel and work your way down the list.

 

Ive done it all man! The bike is in the shop and we have hit every possible lead... Ive replaced the fuel pressure regulator got an air box cover... Im just lost... When I throw fuel over the air box it will fire up but after that it dies out and all I get is it cranking again... How can I reset all the error codes? Ive walked up and down the fuel rail and everything is good... Hoses arn't clogged, I have pressure from the pump thru the hoses, just am lost... I have quite the list of error codes that come up when I pull the diagnostics up thru the dispay... Any help would be great thanks guys!

 

the on-board diagnostics wil test absolutely everything individually for you.

to access it,
-turn the red kill switch off..
-hold the 2 buttons on the dash down
-turn the key "on"
-wait for "DiAG" to pop up on the display, then release the buttons and depress them simultaneously again
- when a code (i think 01 and a number) pops up, you're in the OBD dealer access mode. use the dash buttons to toggle thru the different tests and use the kill switch to cycle that test, if availale.

turn the killswitch on, then back off to cycle.

it's been a LONG *** time, and i can't remember what the pump relay test parameter is, but i think it's in around 33 or lower 40s.. i wanna say 30-33 was coil packs 1-4 and 34-37 was injectors 1-4 ,and I THINK (sorry i can't recall..) 38 mighta been the pump cycle, 39 i wanna say was the air solenoid, and 40 was the fan and 41 was the headlight.

the codes and procedures are outlined in the manual.. if you don't have one, go to the stealership and have them print you the code sheet from the book. if they're not *********, they will.

to reset the codes i think it's 70 or 71. turn the killswtch on then off again.

good luck and keep us posted bro



edit.. saw you already know about pulling the codes.. sorry for the bullshit post..

re-edit.. lol.. what codes are you getting? sounds like everything ignition-oriented was ruled out the second you primed it and got it to run that way.. got spark, got timing both ignition-wise and with the cams, good pickup coil andcam sensor, good coil packs (a HORRIBLE weakness on the R6 for a while..) gotta be fueling or mis-ignition after fire up.

 

Yeah Ive run thru all the test I could... Im getting power outta my fuel relay, I have spark, Im not sure on time with ignition and cams... What do I need to check for? Where is the pickup coil and cam sensor located at? That was one of my next checks... On the coil packs they are Mitsu's not the Recalled Denso's... Im just lost... Thanks for your input bro! Imma check it out...

 

HAve you tried testing the fuel volume yet?? Sometimes your pump will be running but just not putting out enough to build the pressure and get through the injectors. Pull the fuel line of the rail and jump the pump and measure how much gas pours in ten seconds and reference it to what the manual says

 

shot in the dark but maybe you got bad gas? old gas in a can thats got water in it, or water in the tank. happend to me before.

 

very good point on the water.. if theres enough, it'll just cover the pickup. it's heavier than gas by i think almost 2 lbs a gallon.

do the flow test as well.. could be fuel starvation.. almost HAS to be. the biker runs. that rules out damn near everything right there.. i almost wouldn't worry about timing issues. the bike wouldn't start (on ether) if the timing was compromised.

threres a filter inside the pump shroud in the tank that is kind of a bitch to acess, but is always worth a shot to inspect as well.. if theres tank rust accumulated there, it'll obviously kill flow.

weird **** homey.. flow and pressure is what i'd test at this point personally..

vac feed to the regulator and all that ****.. i'm sure you've already gone thru that..
