Hello newbie here I have a 1985 honda vf700f interceptor I cleaned the carbs put them back on and the bike will not start I just purchased it by the way.any how the fuel pump has no power going to it .it does test ok and there is no spark going to the plugs can anyone help me with a place to start from here??
Build a new wiring harness. Better than Honda made it. Use larger AWE wire, wire into a central fuse box that is easy to get to. Use metal connectors and crimp with a McDaniel's crimper. Cover splices with 2 layers of shrink tubing. Your harness is soooo old its best to start from scratch, and do everything at once. Its really the best way. Happy trails :o) Ms. Traci
the wiring harnes looks fine still no power going to fuel pump the ground checks out good there is power going to the relay still have no clue what to check next.
Okie Dokie...How good are you at troubleshooting electronics? You have a short/open or just something causing a lot of resistance. Follow the lines from the plugs and fuel pump. See if you have continuity. Their may be just one problem, or you have 2 separate problems. If you have 2 problems you can isolate, new spark plug wires and plugs. Perhaps and a new fuel pump if you have 2 problems. If one - go up the line from where they meet and check resistance - if so you only have one problem. Then you replace the damaged circuit (cheap fix if you are lucky). Regards Ms. Traci
OK spark pluggs give me a break they have nothing to do with why the feul pump is not working.I did swap out the relay that did not work.Bike will be in the show soon so it can be looked at thanks any way.
hey not to offend, but you know that the fuel pump on an old v4 honda only works when the engine turns over, right? Not like a car. they can be a bitch to prime the carbs sometimes when they're completely dry. you can use clear hose to run from the tank down to the pump and with the seat off you'll see bubbles/fuel moving when you crank the motor if the fuel pump is working. hope this helps
When I had it running the pump did not work I know this because i had a funnel hooked to a hose and it did not take the fuel in .thats ok bike will be in the shop next week to see what the problem is.. for anybody out there needs hard to find parts check out pacyclesalvage.com they do not have a toll free # but it is worth the call..will post when i find out what the prob was...
Ok bike still in shop have the not starting/week spark issue cleared up it was the 2 spark units under the seat all set now they have to get the pump going and i should be on the road!!!
