i'll bet ya a dollar, once you replace the fuel pump, maybe clean or replace the injector ?, it will fire right up..bet ???..lol.

Hi shadetree, just wanted to give an update. I did replace the fuel pump with a new OEM and it fired right up. Thank you very much for all the help and support

id like to know an update on this myself. 

Hi, sorry just now saw this. I ended up replacing the ecu and the fuel pump with an OEM replacement. FYI, never try using an aftermarket fuel pump. They do not supply enough pressure for it to run. Hope this helps

I was thinking that also but wasn't sure because it is getting fuel and I was thinking it would atleast try to run. I'll replace that and go from there

Ok gotcha, do you have any other ideas before doing that?

Not long at all. It has brand new fuel pump and filter but it isn't OEM. You think that's the problem? Maybe it isnt giving it enough pressure? Thing is, it is getting fuel so you think it would atleast try to run at first 

I actually just tried that right before posting and it still wouldn't run. I have another fuel injector ordered but I soaked the old one and plugged it back in but before I installed it I tried starting it and fuel sprays out good

Hey guys, I'm having an issue. My 07 honda rancher trx420fm 4x4 will turn over but not start. It is getting fuel and spark but won't run. I tried a little ether and itll run for just a second but that's it. Any ideas?

For anyone that's wondering what the problem ended up being, it was the pcm. 

Gotcha lol

But I did just replace it

Nevermind, that's the one you said check with the peak voltage adapter 

Melatv, I believe the ckp tested to be good but I'll check it again to be sure

I'm at work now. So you think the fuel pump is requiring too much voltage and is shorting the relay?

So you think the fuel pump is shorting the relay out?

Yes it is lol

Hey guys, question please. I figured I'd test the fuel pump/engine stop relay again since I replaced the stator. When I tested it, the engine stop ohmed good but the fuel pump side didnt. I had a spare so I tried it. Before I plugged it in, I tested it and both sides ohmed good and when I connected it to the battery it would click. After I tried it (still wouldn't prime), I tested it again and it wouldn't click when connecting it to the battery and when ohming it it wasn't reading 0.00 anymore. It would read 0.1 or 0.2. So is it being shorted out?

Hey shade tree, I just now saw you replied. I have ran a wire straight to the fuel pump and it did run but the four wheeler still wouldn't start. I'm not really sure where to go from here so I'm just starting to replace parts

I wish I would have seen these before. I used some liquid electrical tape over tube connectors. Im not sure how good the stuff is and It doesn't give as clean of a look.

Well, I swapped out the alternator successfully and to no surprise the fuel pump still isn't priming and still not getting fire. I'm glad to rule that out though. You think it may be the wiring harness or are there still other possible issues?

Yeah I know lol. I knew it was taking a chance. I'm just tired of testing and I'm ready to start replacing !. I was going to take it to a shop but after all that you and others have had me try, I don't trust they would know the problem right off and would cost mean arm and a leg once its said and done so I decided to do it myself. For the price of the peak voltage tester I figured I'd might as well buy the part. I knew it would be a job but it was a little more than I thought. I did get it off and replaced. I'm in the process of putting it back together now. I do like that I've learned through the process. 

Yeah, there's a lot more to this than that video shows. I had to take the swing arm loose in the rear to remove the axle. I can't get the starter off or the front shaft and without removing them I won't have room to take the cover off. Wish I had full coverage I'd burn this piece of junk lol

Alright, will do. I appreciate that 

Hey melatv, I tried that again and still the same thing. It'll turn over but won't start. I ordered a used but tested oem ckp/alternator for $27. I'm gonna change that out and see what happens 

Nevermind, I remember there's a voltage drop when trying to turn over

Melatv, if the ignition coil was bad would it prevent the fuel pump from priming?
