HELP! Can’t start 1988 Honda Fourtrax 300 ATV!

Recommended Posts

So I have a Honda Fourtrax 300 year 1988. The ignition doesn’t start it with no sound. The headlights won’t turn on. It has a brand new charged battery, fuses are good, oil is good, gas is good, reverse is rusted, it shifts good, won’t jumpstart but when you try it will turn over, it will start if you jump the solenoid give it gas and spray starter fluid on the breather but it won’t stay on long but will stay on for the little time it does by itself. I don’t know what’s wrong and I need help!

Have you checked the main fuse located next to the starting solonid.  Look at that solinoid and see if there’s a fuse right next to it under a rubber cap.   Make sure you’ve gone through every fuse and connection. Try to wiggle the key while it’s in the ignition and see if anything happens. Sometimes it’s a bad ignition switch.   Checking the power to the switch is a good idea like @David Peterson mentions.   If you don’t have power after all of that the you have to start looking at safety switches like the neutral safety switch and the kill switch etc.

sounds like a push button and carb issue to me.  Have you cleaned the carb yet?  maybe check compression, valve clearance, spark plug, timing while you're at it- could be factors

Steven, first thing I would suggest is getting the starting issue done first.  you have to get 12vdc to the key switch. That 12vdc comes from the battery to the solenoid. Then through the solenoid usually via a connector through the wiring to the key switch,  Then when you turn on the key switch on. it sends that 12 vdc every where else it needs to go.  So check the key switch for 12vdc. If you don't have it there go back to the solenoid and check both sides of your fuses. Check you battery ground too. 

I'm not looking at a wiring diagram for your fourtrax other wise I could give you the wire colors. 

Bottom line no power to the key switch nothing else will work. Get it to crank first then look at the carb/ fuel issue.

yea def get it running before you worry about the carb.  On mine, i wasnt getting spark until i ran through the wiring harness and greased all the connections.  with a bike that old, its easy for the connections to corrode and not connect anymore

      I am working on a Honda sportrax I just got my daughter for get birthday and the reverse and neutral light are not working. When I traced the wire down I saw that it wasn't plugged in but I don't see where it is supposed to connect. Does any one have a general idea of where I should look?

      Hey everyone...does anyone know if tie rod sets for a Honda 250 will fit a 125? My son just snapped the tie rod end clear off. We have a 1987 Honda fourtrax 125. Just want to make sure before I order the set off eBay. Thanks

      Hi, I’m a 16 year old that is wanting to get more into vehicle and mechanic repair. My dad has an old ‘96 Timberwolf that he doesn’t remember running since I was born. I want to get it running again as a memory for him and to help us be able to hunt together, and of course so I can learn how engines work more than the little information I know now. I’ve pulled the carburetor and gas tank off of it, and the carburetor is getting cleaned by a friend. I can post photos of the condition it’s in later, I’m just curious where I should start in my journey to get it running again. The power switch is broken off of the handlebar, so I am looking into fixing it, along with the pull cord. I’m afraid the engine is seized up, and I’m curious to hear any input anyone has. Thank you all.

      Hey everyone, hoping to get some help here... my kids 03 KTF 50 Quad has always ran great... they were riding it a couple of hours a few days ago and it died a couple of times (not normal) but started right back up. A few days later my 5 year old wanted to take it for a spin so I started it (2 pulls) and he took off.. he made it a couple hundred yards and it died and we havnt been able to start it since. I have new gas, good spark and 120 psi compression.. it will not start with starter fluid in the intake or even in the cylinder.. the fuel bowl has fuel at the carb... what am I missing? It’s driving me crazy!!

      Hi guys.  First post, hope you can help.  As above 1991 Honda fourtrax.  Starting, running fine until a few weeks ago. Used primarily to put my ski boat in the garage (put 2" ball on front).  Any way, had just backed boat into garage, turned off to crank trailer wheel down, when I went to restart got nothing.  
      No neutral light, no headlights, no reverse light, would not turn over when start button pushed.  It would crank and run when I jumped the contacts on the start relay.  While running the neutral light will come on, although it is dim and flickers.  Reverse light on when running and in reverse.
      What I have done to this point:
      1.  Used jumper cable to ground battery (-) terminal to engine block thinking ground wire from battery to engine may be bad.  No neutral light, no start.
      2. Applied 12 volts to start relay.  Got a loud click like it was making contact.  I didn't have the battery/starter cables connected to the relay, but I am assuming it would have cranked at that time.  
      3. Disconnected neutral switch wire.  Grounded neutral switch wire with jumper wire. No neutral light, no electric start. 
      At this point I am thinking ignition switch vs broken wire in the harness going to the neutral switch (due to dimness and flickering when running).
      Any and all suggestions to help track down this issue are appreciated.
      Thanks
