Top 20 Polaris ATV Questions & Answers

When it does not start spray come starter fluid into the throttle body/carb to see if it will run. If so, it is a fuel problem. Also check electrical connections for looseness. Possible contamination of the fuel with water.

My guess is that Chinese carburetor is not jetted or set up right. It may not even be opening fully. Ask in the Polaris forums. Top speed should be 45 mph. https://www.google.com/search?q=2001+Trailboss+325 ..

I am working on the same machine that has not been running for quite awhile. I'll let you know what I learn. Did you find a manual? Gus

5 years standing is a long time. Carburetor float will be stuck. Pull the plugs and see if they are wet and also if you have a spark. Strip and clean carb and jets. Check fuel tap and fuel delivery. Drain any fuel and replace with new. Replace the spark plug. No lights is odd. Check if there are fuses?

Follow the positive cable from the battery,it will go to a terminal,which will lead to the starter.

I presume You mean a Polaris Explorer 400 ATV, rather than a Ford Explorer 4.0 litre? I did some edits to fill in the blanks, but Fixya have mixed up the image for Polaris Pool Cleaners :>) Your oil pump is important, so you need to check inside or just replace it. The other place to watch for pieces of aluminium casting is around bearings and seals. If they fail, the damage can be great, but castings can be filled and machined.

The 20 Amp fuse (diagram shows only one 20A) feeds ignition coil and fuel pump circuits. With a current probe measure the two circuits separately to identify which is most probable cause.

Check battery voltage with engine running. It should be well over 13 VDC.

If it will run for a few minutes, you might get by with a touch test of the ignition coil and fuel pump. If one is markedly hot, the heat likely identifies the culprit. But a current probe is the tool necessary if you want to avoid part$ swapping.

Recommend fuel pressure check also. Eccessively high pressure could be problematic and low pressure would further implicate fuel pump.

This will depend on how much you need to adjust it. Small amounts can be made using the cable sleeve adjusters. At each end of the cable sleeve is a nut shaped connector. If there is a small thin nut slacken it a couple of turns. Wind the larger nut out to tighten it and In to slacken. Use a wrench, (spanner), to hold the large nut still and re-tighten the small nut to lock it. Some versions don't have the smaller lock nut so you just wind them in or out. If you need to move it a large amount it might be easier to just replace the whole cable.

Your engine codes should only be in two digit numbers and you should not have codes that end with any zeros.check engine light should flash like count the flashes three flashes pause then 6 flashes would be code 36 then longer pause between codes then you have more than one code after a long pause it may flash 4 times then short pause then two flashes would be code 42 witch is engine coolent temperature high voltage a code 56 is fuel pump open load/short to battery or short to ground should start with one flash short pause then two flash meaning 12 then codes will repeat ,to start flash engine codes turn key off and on three times in less then 5 sec then leave on

Ok the 6 amp fuse is for the ecm the 15 amp fuse is for the cluster one of the 20 amp is main power the outher 20 amp should be for the starter and charging circuit .your over heating problem could be in the fan temp sensor you will find it on the left side of the machine on top of the thermostat housing , take and disconnect the plug on it and jumper the two wires togather with key on fan should come on if it does replace fan temp sensor .if not visibly pull each fuse out and look to see if is burnt odds of the fan being bad is very uncommon. This will be all good if is an EFI 800 hope that is helpfull

You have lost power to your ignition when it is in the on position check fuses or look for broken wires leading from ignition switch it could very well be in the switch it self

Odds are your carb needs to be taken apart, cleaned, reassembled and adjusted if needed.

define "stopping". If it involved using the new ignition switch, then I think a return to the dealer is necessary. You know it takes 3 times for them to get it right?

Will the crank shaft turn I would take the plug out and use a 1/4 in exstion and put it in the sparkplug hole needs to be about 10in to were it dont fall down in there and push to make sure the motor is not locked up

Need to test to see if power is being sent from the key switch to the ignition I would think bad fuse or bad ignition switch
