Hey guys my honda rancher 420 stalls when you come to a stop then apply wot. it only does this in gear, and the idle also drops really low when coming from a high speed to a stop, kinda like is not getting enough fuel. My air filter is clean, i drained my gas and checked my 1 year old fuel filter and pump, replaced the idle air control valve and i have a new ecm. Is there a sensor or something that controls air fuel mixture? could my injector be clogged or bad? it only does this after it has been running a few minutes. Please help, i am just at a dead end...

chances are ?, fuel pump is bad !. the early trx420's were bad about defective fuel pumps after they first came out.

Ok, i am gonna look at the paper work from the dealer for when the previous owner sent it in they flushed the fuel but i am not sure if they replaced the fuel pump. Will i have to drain the gas to do that? Cause i kinda feel like when i put my fuel petcock on OFF fuel still comes out... is that normal?

EDIT: a new fuel pump was installed 6/23/16 along with a fuel flush and injector cleaning job. idk if that helps at all.

if the petcock is off ?, then no fuel should reach the throttle body. you can unhook the line from the throttle body, crank it over, and see if fuel comes out from fuel pump in all settings ?, or at all ?. there is also a fuel pump relay at the battery area, it tells the pump when to..well..pump. if fuel is reaching throttle body ?, then i'd be looking at the injector for problems. this is why I hate fuel injection, when they work..they are good, when they don't work ?, you have to search from one end to the other to narrow it down..lol. with carbs ?, its simple.

I will try the relay then the pump, ill also try the throttle body test too.

if your peacock isn't working properly, it can be gunked up and causing POOR fuel flow, and that can lead to the issue's your having, or just ruining your fuel pump as it sucks air more often like

might want to pull peacock and clean it,m might be full of junk that randomly breaks off and is plugging things down line too!

The fuel pump was replaced 25 months ago.......that's a long time if it just sat up. Anything fuel related is possible at this time. I would assume nothing until I verified it. Drain, clean, inspect and test everything fuel related.

OK, ill try to clean the petcock and the lines. It makes me think its the petcock cause when i drained the fuel, fuel was still coming out when it was in the off position.

The petcock may be failing but that probably is not your problem. I dont remember now what and when things have been done but please save yourself some time and aggravation by doing everything at once. Then you will know for sure what is and isn't needed. Then you will have many years of trouble free service from your fuel injection system.

Are you thinking its something else?

Yes, If it will not turn off that is not going to give you the problems you are describing. Unless you have done any of this within the last few weeks then I would do everything at once. Drain the fuel tank and blow dry, remove the petcock and inspect and clean, remove the fuel pump and filter and inspect, clean and/or replace, inspect and clean the idle control valve, inspect and clean the injector, inspect and test the fuel pump relay. Then you will know for sure everything fuel related has been made as good as new. Fuel systems really ought to be done thoroughly because they are enter related.

Could you tell me how to test my fuel pump relay and what to look for on my injector?

I've owned three of these models but have yet to really work on them........they just don't break down on me. I'm sure there are some here that can give you very specific info on this subject. I presume you can check the relay by just seeing if the fuel pumps works. If it does work then the relay is doing it's job. They relay just sends voltage to the pump on command. To check the injector I suppose you can remove it yet keep it connected. turning the key on should show a uniform spray pattern. Clean it if it doesn't.

Update: I cleaned the injector and tried to clean the throttle body a little. I tried testing the fuel pump by turning the key with the fuel line disconnected. Every time i turned the key only a few drips of gas came out like 2-3. So can you tell me if that means anything? I replaced my Idle air control valve, and I already inspected the pump and filter and that appeared good. Whats next to check the petcock? I already drained the gas also, so i does have fresh gas.

When you were cycling the key on and off and only getting 2-3 drops out. Where do you mean exactly? Directly off the pump, from the injector, etc?

I am getting it from the end of the fuel line that would connect to the fuel injector. Also I tried to take my fuel petcock off today and the bolts were almost like skipping as if there were a nut on the other side? I tried PB blaster but the bolt kept doing that... It says ULL right next to that bolt if that means anything? They are the two bolts that mount it to the tank...

Update: I read on a rancher 350 forum that those bolts wanting to skip is normal and that you just need to hit them with an impact. Well i tried that plus pb blaster and a serious beating with a hammer and they still wont budge... idk what to do now...

 

[shadetree]

just from what you said about what little fuel your getting from the fuel pump ^^ ?, tells me, your fuel pump is bad ?, or your not getting any fuel to the pump ?.

So if i am already replacing the tank and petcock should i just go ahead and do the pump or wait and see if the petcock fixes it? IF so oem or aftermarket pump any brands in particular?

Also can anyone show me a picture of what a dirty fuel filter looks like? i am not sure if that's whats bad with mine even though it looked pretty white/clean...
