Anyone have a clue why my 2008 TE 450 isn't starting? Here are the symptoms: 1. The starter motor only primes about a quarter long as usual only when I turn the key on and off or push the on/off button above the starter button. 2. The starter motor doesn't prime itself with every push and release of the starter button like it usually does.
I'm not sure what your problem may be, but isn't the initial priming sound you're referring to in point 1 actually the fuel pump?
Maybe you are getting the short in the pump unit. Have you zip-ty fixed it? If no, there's a thread I'll link to. http://www.cafehusky.com/forums/showthread.php?t=4948&highlight=fuel injection Apparently the zip ty fix is for one problem and some other person found a faulty relay that they found could be fixed. One other interesting post on the 2nd page on a dead pump coming back to life.
How much fuel is in the tank? Are you sure the electrical connector is seated completely from the tank? That's what you get for making it so darn purdy
I can't remeber real clearly, but that sounds a lot like what mine did when the relay went out. I swapped it with the fan relay until I got a new one.
There are 3 relays under the tank, little black boxes, and if I remember right, they are marked on the grey leads to them what they are. Unplug the fan relay and plug it into the fuel pump relay and see if it fixes it.
Thanks! I found them...they are grey and don't have any distinguishing marks between the three. That and my buddy Greg (thank you) got me snooping around all those wires and what do you know? A wire to the coil had worked its way loose...problem solved!
similar problem I was on my way home today riding my te510 on it's first new tank of gas since it came out of storage. I was accelerating hard, heard a loud pop and the motor stopped running. Motor cranks but fuel pump does not come on. Spark plug looks normal and compression feels normal. I think maybe a backfire could have damaged some kind of sensor in the throttle body, but I'm not sure it was a backfire since I was accelerating when it happened not shifting or bogging the motor. Everything looks fine from the outside. I pulled out the throttle body and everything looks fine the intake valves look good from the top. The neutral light blinks and I tried to decipher a pattern. Looks like short flash 4 longer flashes then a short flash before repeating. I could be imagining the pattern because it is definitely not pronounced. Fuses are also good unless there are more than the 3 that I know about. I bought the bike in Hawaii and am now in spring lake, NC. I cannot find a dealer around here. My left rear relay clicks when I turn the bike on. I swapped the other two and nothing changed. I don't know if the second relay on the left is the fuel pump or if both the left relays should come on. I also put power to the pump directly from the battery and it works fine.
Have you taken a continuity meter or test lamp to the fuses? It's sometimes hard to see an open. One of the left side relays is the "power" relay which is controlled by the ECU and is normally energized 2-3 seconds after the ignition is turn on and is continually energized after the engine starts. It supply's 12v to the pump, O2 sensor and ignition coil. The other left side relay is for the fan and the one on the right is for the DC power which powers headlight, horn and brake light. The power relay gets coil power from the V fuse, but switchs power from the P fuse. If you here the relay click on for few seconds and you know the pump works, I would double check the fuse and wiring. It's unclear what happen first; the backfire or no pump power. If you had iBeat you could read and reset the error code.
Ok I feel like a moron now. I had only checked the fuses by shining a flashlight through the back of them. None look burned out but the furthest back fuse had a small crack in it, which I found when I tested with an ohmmeter. The bike now runs. thanks guys. the bike is an 08. My owners manual say the relay on the right gas/brake side is the fan relay.
I'm glad to see you found the bad fuse. Did it look like it was melted from an over-current condition or broke from vibration fatigue? If was an over-current failure, I would inspect wiring that connects the pump, ignition coil and O2 sensor. One issue I have seen it that it's easy to get the fuel pump cable pinched between the tank and frame. Another lesson that should be taken from this; carry extra fuses on the EFI bikes. I have spares tape under the seat just in case.
I had a similar problem with the fuse box for the lights. but on a similar point of the bike cutting out i was driving it when the fuel pump stopped working, it took me ages to find the fault which was the wiring loom rubbing on a brass fuel elbow which supplied the injection unit on the engine, a simple short to earth but a mega pain as i was miles from know where.
If you guys dont mind I would like to share a problem that I am having with my power relay circut as well. I have a 2008 TE510. I found that I had no power at the fuel pump and coil. I check the fuses and all are good. I check for power on the swithed side of the power relay and I have power all the time. I check the coil side of the relay and I have power with key on. I check for ground on the ground side of the relay and I have about 7k ohms for about 1 second and then open. I can over lay my own ground that should be supplied by the ECM and fuel pump and coil work fine. I have checked the two grounds that go to the ECM and both are good at .2 ohms and no short to power on those grouds either. From the crapping wiring diagram that I have and wires that I have ohmed out it looks like with key one power is supplied from the power unit interface to the power relay. Then the ECM gives the ground to allow the power relay to switch. This is what turns the fuel pump on for 3 seconds or so when key is turned on then is powered up agin when engine is running. I called some dealers up to check on a ECM. Not one has ever heard of an ECM going out. I have double and triple checked myself and everything points to the ECM. It just wont ground that circut. Has anyone seen anything like this or has any other ideas? Thanks
