TRX350D fuel pump problem
Brilliant, cheers, there is a good spark so it sounds like I have either a broken/poor live or a dodgy earth so hunting for that will be tomorrow's task 👍 -

TRX350D fuel pump problem
The fan gets switched on when the oil temperature gets high. The fuel pump gets turned on when you first turn the key but then switches off unless it's getting a pulse from the cdi. The pulse from the cdi is the same pulse that fires the ignition coil, so if you have spark, you have the required pulse to operate the fuel pump relay, you just need to ensure it's getting to the pump control relay. When wires have no continuity, or have high resistance, it's almost right at the end of the wire where it crimps into the metal terminal, it either corrodes or breaks the wires inside the insulation. Wires do sometimes break if they have been chafing for a long time on something and worn right through the electrical tape, insulation, and then the copper wire, but that's easy to spot by the frayed insulation.- 1

TRX350D fuel pump problem
As i recall the motor controller, a very expensive part and no aftermarkets available, is activated by the CDI, and it absolutly has to have a good ground to operaate correctly, including the fan, the controller itsself may be grounded through the CDI, not sure, i am having trouble relating what i know to yours because the one im more familar with didnt have a fuel pump. I think what you are doing stripping the wiring loom and checking is the best way to find it, you can throw expensive parts at it all day long and still may not get it. You have worked hard at it i havent been much help, but good luck. -

TRX350D fuel pump problem
What you say makes perfect sense but I think I must still have enough fuel in the tank to allow it to gravity feed as I tried removing the pressure line and blew into it...still nothing!! I gave up yesterday after stripping the whole top end and the wiring loom. Fuel relay working on rpm makes sense but I don't know what activates the fan as I can't find a thermostat!! Will have another go later today...... -

Thanks, no, I haven't noticed any other problems. I have now stripped out the complete wiring loom and will now test each of the wires!! -

1997 Yamaha big bear 350 Shift shaft issue
Yeah it does sound like a bad switch, you can take them apart and clean them up, but for this level of inconsistency i would just replace it . Aftermarket ones are fairly cheap and i havent had any problems with them. -

2005 Bombardier Traxter 650 CVT Compression? Tops out at 20 MPH.
Bought a brand new sparkplug coil. It measured 1.6 Ohms. It was harder to start, backfired more and ran same as old one.
