Trying to get my 97 vfr started...help?

Ok, so Ive gave it a tune up and got it to turn over but the fuel pump isnt getting power>? Where is the fuse for it? I checked all the fuses on the fuse box on the front of the bike. Plus now I tryed straight wiring it to the battery to see if it was bad and melted the wires...that was fun. Any help would be great!

Thanks,
Smiddy

 

It is on the same fuse as the starter (D), so It is not the fuse. If you hooked up the jumper wires correctly, then the melting suggests a short in the pump. If there was a short, the fuse should have blown, thus not allowing the starter to engage. hmm...

Did you forget to open the fuel valve (petcock)?

:crazy:

 

well Ive now figured that when i turned my key the fuel relay isnt clicking so Im going to replace that first. straight wiring it wouldn't have help either way...

 

Sound like the relay is toast, Hope this is the only issue. Good luck

 

I lol'd at work. People looked at me like im crazy for bustin out laughin for no noticeable reason.


One thing not really explained here.

Was it working BEFORE this "tune up"? I got to say... if the bike looks like it does today in the photos posted... it needs some love.

 

Just wait a second, cowboy.

The fuel pump relay is electronic, not mechanical and does NOT click.

Proppa proceedure is to bypass the relay with a single wire in the plug, then see if the pump will come to life, just as the good book says.

You can also test the pump with an ohmmeter: if you get a low ohms number across the two wires, then the pump MAY work, but zero continuity means no-go.

 

squirrelman,
So just use one wire to bypass the relay, and what do you mean in the plug?? Im guessing i didnt wire it correctly since it nearly fried my wires..I ran two from the battery to the wires right before the pump. One goes back to a componit just behind the fuel pump and the other goes to the bundle of wires just above. The one going to the bundle is the one that burnt up some.. and the one I used to connect it! So detailed instructions would be helpful, Im thinking im just going to have to wait and get it to someone that knows more about motorcycles then i do..so i dont f it up any more..

 

If you just simply read the service manual answers to your questions would be found there.

"Bunches of wires" isn't very explanatory.

Go directly to the plug that attaches to the pump relay, and disconnect it. Then use a jumper wire between the two wires to send power to the pump when the key is on. You might have popped a fuse when that wire almost melted. Just hope the one overheated wire didn't damage other wires in close proximity as shown in the top photo.

 

I dont know where the fuel pump relay is....ok correction.

part # 18 is the fuel cut relay.. I tried to bypass this and nothing happened...

And bikebandit has almost nothing for VFR's that i can find.

 

BikeBandit.com has some great schematics for all kinds of bikes... go check it out.

 

You can also run a wire directly from the battery to the pump connector, blue black wire is power and green is ground. the green is a constant ground so you only need to run battery power to the one connector in the plug. The pump only runs when the engine is turning so just turning the key on will make pulse once and that is it until it is cranking or running.

 

couple hundred miles away from my service manual so I may be wrong aboot the wire color but I am pretty sure the color is correct, but the ground is always green.

 

Is my fuel cut off relay and fuel pump relay the same thing??

I also just discover that the center top wire to

Set regulator isnt connected... ran another wire to the started still nothing.
Checked fuses and gas cut off valve...Im at a loss?

 

Just bypass the bloody pump. I did this on my vfr and It never gave me problems, but you must have the air filter on in order for gas to get sucked into the carbs.

 

Hey Smiddy well it's the 4th hope u got her running since then, did u replace the fuel pump relay? mine was out also so i installed a toggle switch , using the hot wire on the relay connector and may want to put a fuse in line also then the other wire from the toggle feeds the fuel pump wire dont use that third wire in the connector 'cause that's a ground wire ,. i need some pic's of the tree gas connector thats under the gas tank, where the original gas lines r hooked to the right carb lines, mine is the '91 750, thankz keep Revvvving,...

 

OK this is great new's, so i can bypass the pump and relay? I haven't got it started yet kinda gave up and letting my hand heal (burned it when i burned up the jump wire). I'll post pic's in the morning of the gas tree. I have toggle switch and wires w/ fuse already so thats a good thing. I will need step by step instructions when I start this but mybe i can call you Hollywood?? Im dying to get this thing started!! Thanks everyone!

 

If you have the service manual, go to 18-17 (page 292) and follow the tests layed out there. If you don't have it, click this link. http://downloads.hondatech.info/Moto/VFR/HondaVFR750F(90-96)_English.pdf Don't worry about measuring the the flow rate, just want to know if it works. I'm not a big fan of redneck repairs, unless there are no other options.

Come back to us, when you have the test results.

:crazy:

 

Ok so the pump is out..I want to go with a gravity feed i believe from what Im hearing.

Update: I heard it start for the first time!! I bypassed the fuel pump (not correctly Probably) and primmed the engine with gas and it starts...shortly dying afterwards due to no fuel getting to engine...? any thoughts? Going for gravity feed fuel...

 

ITS RUNNING!! feed the fuel line straight to the line comming out of the fuel pump and primmed the engine and ITS RUNNING...just a little hot though..I put 3 1/4 quarts in it and the coolant is good? is it just cause its not moving?

Ok well it was running, now its acting like its not getting fuel again? Any thoughts?
