Honda TRX 350D

Hi all.
I have a problem with my 1986 quad. I was out on here the other night, and it just stalled for no apparent reason. Tried to start it up again, but was a no go. Ignition was ticking over, but wouldn't kick into action. I checked fuel and had plenty.
I ended up pushing it home, 3 miles. Never realized how heavy it is until then.

Anyway, when I try to start it up now, same thing happens. Only now, I can't hear the fuel pump ticking when I first turn the key. I checked that all the cables were connected, and everything seems to be in place. Problem is, she is quite an old and battered thing. Most of the nuts and bolts that hold the plastic panels on are rusted solid, and I can't get them off without either drilling them out or breaking the plastic. And I am certain that there are connections that I can't reach or see due to this. Am I wrong? Or am I barking up the wrong tree?

Any advice would be greatly recieved.

Welcome to the forums. If the fuel pump isn't working, I would check the fuses.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Where are the fuses on this quad? I have checked the book that it came with, but doesn't mention any. And I have looked, but can#t see them.

It's been a long time since I worked on one of those, I can't remember for sure, but I'm thinking they're somewhere behind or around the battery.

Found the fuses. All fine, not burned out or even slightly fractured.
Test for a current to the fuel pump. It sparks when either of the contact points are connected to the carburetor. So it isn't the wiring either. Do you think I need a new fuel pump?

Try unplugging the fuel pump and running power straight from the battery and see if the pump will work, then.

Tried that and no.
I took the top off, and pressed the connector down inside with my finger. That arched a bit, then stopped. I then started the engine first time. I let it run for a couple of minutes, then switched off. I put the top back on, and tried it again, but nothing. Tried it with my spare battery, but again nothing.
I am no mechanic, so need somebody to confirm whether or not the pump is knackered. I think it is, but I just about know where the petrol goes and not much else.

I couldn't really understand what you did above, but if you ran wires straight from the battery to the fuel pump and the fuel pump won't run, then it's bad.

Don't suppose that you know where I could buy a new one? I have had a look online, but all the ones I have found look different to the one that is already on.
