Fuel pressure is good. Won’t even fire now. Just turns over and over. Sounds like it kind of wants to fire but doesn’t.

Finally got it to start. Still runs the same. Hesitates off the throttle but is fine after about 5mph. Holds good at idle doesn’t stall. Any thoughts on what to check next?

What was the fuel pressure?

 

[vortec59501]

She’s pushing around 58.

Man, I would of bet my bank account it was gonna be the pump. I I wish it was lol

 

[RJ]

Does it rattle bad on start up?

 

[vortec59501]

Nope. But when I was trying to get it started I stepped on the throttle and you can hear some popping sounded like it was coming from my intake. When I did get it started it makes a weird weird noise when i get on the throttle it’s like a hollow noise. It’s super weird. I tried to record it but you can’t hear it in the video.

It’s like something is holding it back until I get it up to about 10-15 mph then it opens up.

Maybe fuel build up in the plenum?

Time for a compression test.

Next time you have it running, spray some carb cleaner around the intake boots and listen for a rpm change.

I changed those out about 2 months ago.

Leaking?

 

[vortec59501]

No. I had some idle issues this early spring so I ordered a set and replaced them but come find out it was bad spark plugs.

2013 Polaris Ranger 900xp. When I first get on the throttle quick like it’s bogs down and spits around for a second then as I increase to anything g above 5mph it’s completely fine. Any ideas? Tried searching but all roads lead to bad fuel pump but it runs amazing anything after 5mphs. Any help is appreciated.

Can I ask a similar question to this thread stating what we’ve done to date?

 

[Layne]

We’ve done many things for this similar problem. Can I list to see if there is anything we missed. Another weird thing is higher elevations make it run better
