Welcome to the forum.

Which year is it? Does it fire right up or does it take a few seconds? Do you have air lid on or off?
If it was running with no air filter I'd say it has to do something with the dirt getting in but since you mentioned that you cleaned it .. I have no idea. I mean it should at least run. Even if poorly.

 

2008. Takes just a second to start but I have to give it gas, the air box lid is on, when it starts I have to pedal the gas to keep it running and it sounds like crap and as soon as I let off the clutch it cuts off

 

It's possible the fuel pump is going bad. There is a reason it blew the pump fuse from drawing to many amps. Also, try cleaning the injector. Use a 9volt battery to open the injector and put seafoam in it and gently blow compressed air through both ends while it's open

 

Ok so I played around with the tps (throttle position sensor) and I got the quad to idle but if I give it gas it will bog down and try to cut off

 

This is my quad and this is what it is doing https://youtu.be/f_u_qcgsEFI

 

Try putting the air filter and lid back on.

 

How did you clean the TB? Pull it and re-clean. Soak the injector in Sea Foam or carb cleaner. Flush as above with carb or brake cleaner. And yes, it needs a air cleaner, not just a sock. Watch the sock, it's sucking in, so it is dirty/restricted. Clean it or toss it. Turn your idle screw in slightly. Check your battery voltage for at least 13.5 volts. Trickle/float charge for a few days.

WELCOME TO THE FORUM.

 

It sounds like it's getting too much fuel. Are you sure it doesn't have a fuel controller?

Low voltage or a bad charging system will increase amperage. Amperage creates heat and blows fuses. Check your battery voltage and charge as necessary. Check cable connection for shiny clean and no corrosion (white powder) between the cable and connectors.

 

Is it blowing black smoke when you try to rev it? If its not, it seems like a mega lean condition to me just from the video. Definitely don't leave any stone unturned though. But if it was just running fine then it blows a fuse and now it don't run right all the sudden, I would for sure go over the whole fuel system, including tracing the wires to the pump, looking for any wire damage. Fuel injectors do clog and require them to be open in order to properly clean them out. Also if the pump is running with drag, because its wearing out or clogged with dirt or debris it can blow a fuse by drawing more amps. Also make sure you have enough fuel and the gas cap vent is breathing. Blow through it to check.

 

Not ignoring what y'all have said but I wanted to mention that if I take the tps off and manually turn it as I give it gas it seams to run fine but if I put it back on the throttle body it starts to act up again

 

I don't suppose you have another tps you can try?

 

No I'm the only one around here that has a raptor and a new one is $80....

 

Yeah at that point I think you've isolated that it's the TPS.

What year is it? The 06 and 07s were notorious for going through TPSs. They changed the TPS design slightly in the 08+ which solved the problem

The TPS is sensitive to water, especially a pressure washer. The '06-'08 TPS electrical connector points up. The '09 and newer has the connector pointing down. Try drying it with a heat gun or hair dryer.

 

It seems like it's getting to much air because if it was getting to much fuel it would be blowing black smoke correct?

 

After you get the tps figured out, you need to have an air filter and lid on it. It will not run right like that without a fuel controller. Can actually cause damage. It would be black if it's dumping fuel. Just from the video, my initial impression is it's dangerously lean.

 

What could be causing it to run lean besides the air box and filter.... Tps or exhaust?

 

As far as I know the parameters that determine how it will run are determined before the ignition chamber. So the problem is caused between airbox and piston. The exhaust has some effect but not this much that it wouldn't run.

 

Put your air filter and airbox lid back on. Then continue with debugging. Friends chinese atv didn't run properly if you took the seat off. It changed the airflow a bit and it ran like crap. If you took airbox lid of it didn't even start. Makes you wonder ... Like it has been suggested I too believe it is getting to much air and since it has no fuel controller it is not compensating for that extra air its getting.

 

If it was me, I’d follow ALL the suggestions mentioned. The cleaning, charging of battery, installing an air filter, and I’d set the tps per the manuals instructions, I’d change the spark plug, and empty and clean out the gas tank. Get the bike as close to “right” as possible, and go from there. The 1/2 wit that owned the thing before you didn’t take care of it in anyway. The folks on this forum are damn good, but you got a lot of “could be’s” right now. Keep us posted and, Welcome to
The Raptor Forum.

+1 for sure

 

Thanks for all the input I'll start doing what y'all have recommended as soon as I get home

 

Ok so far I've charged the battery its at 12.43 and set the tps to .63 and the fuel pump in drawing 12.38 and it's still not running

 

I believe battery should be 13.5? DEZ mentions this on the first page. Not sure if it is the factor there, but it's possible. Wonder if it slipped time at all by a tooth? Meh, that's the deeper portion mentioned in post #24.

 

Ok it started back firing like crazy and blew the throttle body off.... Could it have jumped time, or the valves need adjusting it an 08 and I highly doubt anything has ever been done to it?

 

Are you close to Saint Louis Missouri by chance? I'll get it running for you free of charge

 

Checking timing is super easy. From the video you already have it ready.

 

Here is a quick link on how to check valves. Timing marks are involved in the thread as well.

http://www.raptorforum.com/forums/8...rchived-threads-product-reviews-how/4509-how-adjust-your-700-raptor-valves.html

 

Back fire is either jumped timing, leaking/bent valve(s), or lean fuel. Check your timing marks, it's not hard.

 

If those valves are gaped within spec. I"ll....well, I don't know what I'll do but it'll be drastic. Also, way to go Blakeh! For following the advice given instead of just blindly posting more possibilities. You'll get this.

 

Fresh plug every time. Pick up two or three. Once fouled it will never run right. Adjust your timing and valves then add a new plug. Your timing tensioner could be maxed out and chain stretched throwing your timing off. But a valve adjustment is free and easy. It you run a 3” deck screw with a #2 Robertson head into a piece of wooden broom handle it will act as a great tappit adjuster tool.
