No start, No run!

[sharpie1]

So my '09 TE450 was running ok then just stopped, walked home got the truck and brought the bike home. I've got good spark, fuel pump is a pumpin' but no fuel is getting to motor. My theory is ECU is bad, injector is bad, or...

Any suggestions for further troubleshooting?

Should have stuck with a carbed bike!

no start, no run = not fun....

I'd look around for someone with a donor efi bike and start swapping parts, or look for someone that has an ibeat. I have neither or I would help you.

Sorry you are having troubles.

Plenty of fuel in the tank?

Seems like I was reading where the pump does not pick up the fuel all the way to the bottom so you need ~1/4 tank or so to be pocked up by the pump ....

Found it! The orange wire broke where the Power Commander was spliced in. I'm friggin' blind and missed it and checked everything else on the bike before seeing it right in front of my eyes!

pin #3 where it taps into the harness to get the tps position information?

If so, that seems quite weird....

Yes that wire broke, If that wasnt the only problem than I've got another issue. I had several "open circuit" failures for the injector. I also found one wire on the PC that the insulation pulled out of the plug and could easily have shorted. I'm pretty good with electricity, ohms law, wiring etc...it's what I do but I really dont know enough about all this FI stuff, its effin' magic to me. I repaired these wires and it stared right up. I'm keeping my fingers crossed, I'll find out if everythings OK today.

Just remember that you can bypass the Power commander any time you want to by connecting the injector directly to the injector connector in the wiring harness i.e. removing the pc from the circuit.

Glad you got it worked out
Curious if Ibeat showed multiple open circuits in fault history- is that where you got that information or are you just commenting on what you found by looking at the wiring? ONe thing- if you turn on the ignition without the pump hooked up to the bike- it will record a Fault on Ibeat-
I assume some of the power commander instalation process could do the same expecially if it results in problems with open circuits...

I hate to see these threads- but more and more- (besides a few actual pumps going bad)- these threads are due to wiring completed by installing a Power Commander, fuses splitting from impact and normal abuse, installing or taking off electrical components..... ALL these threads are also quite negative to the bike as being at fault- and EFI being at fault.

I think we start out nervous about EFI and forget to worry about common bike issues. So we blame EFI for spark plugs, coil connectins, bad switches, wireing issues.... This also effects how well we diagnose and adds frustration because of our own insecurities with resolving true efi issues.

So far for me- I have not had a single efi cause or problem- my bike has not left me anywhere. I have about 4000 miles on my bike and avoid pavement and don't commute it. I do not have a power commander. I have adjusted with Ibeat. The only "problem" aside from tuning was related to my coil not being grounded well- because I did not go check the bolts when I bought it. They were a tad loose- after a half a season of riding ( july 2009). The symptom became known and I diagnosed it in a couple hours. BUT on the trail when the sypmtom became known causing stalls and irradic running- the first thing I thought of was EFI even though it was a common everyday issue.

SO my question is- now that you have the bike running again- and I assume its running quite well- are you going to sell it and get a carbed bike?

I-beat showed several "open circuit" faults for the injector. The strange thing was the last time it was ridden was in a full on downpour, everything was wet and the bike developed an intermittent stumble so I figured something was going on. After the bike just up and died the other day I took apart a lot of the connectors (relays, etc...) and most had a little corrosion so i cleaned these as well. I've ridden through deep creek crossings in the past and never had an electrical issue.

To answer your question if I'm selling my bike that would be a big no, I'm not exactly loaded and I still love the bike but got a little frustrated trying to figure out what was wrong and still am a little confused exactly what the issue was for sure, as Coffee pointed out, I'm not totally convinced it was just that TPS wire. I have an '05 TE as well and that bike has been absolutely bulletproof except for self inflicted issues and I suppose the issues I've had with this bike is also from things I've done as well (adding Power Commander). I'm also convinced the overheating problems I had earlier in the year were due to the autotune making the bike run too lean, I would just know better how to handle fuel issues with a carbed bike.

I think if you continue to attempt to seek info on the basic system it will come. I think the PCV may be overwhelming for some who can jet a carb- I know what you mean about that... EFI is voodoo at first. I am not saying I completely understand it.... at all... But its like religion: you believe or you don't and that may go back and forth depending on hardships. I have gained a strong faith in EFI now.

I would have to really study the PCV inside and out- to me: that's complecating a complecation- most think it simplify's efi (automatic). Not exactly... It should be easier than guessing with a PC3. But when you increase parameters from fuelscrew, pilot,idle/needle/ Main and a diaphram pump's timing and duration (keihin fcr) to a HUNDRED separate adjustable parameters- it takes some studying. I am happy the Ibeat with CO1, CO2, and CO3 worked just fine for me- That was simple just like a carb. The efi system does the rest. You just have to tell it the right baseline to achieve.

Keep at it you'll find the right settings and then it will be consitant- I think if I had a PCV and had to diagnose a problem with fueling (beyond tuning) the first thing I would do is eliminate that from the system based on reports.
