20ft Trailer Brake Adjustment + Polaris RZR 800 Won't Start (Fuel Pump Troubleshooting)

Trailer brake adjustment on our 20ft utility trailer, then troubleshooting a Polaris RZR 800 that wouldn't start — tracked the no-start problem down to a likely fuel pump issue. In this video I start in the yard adjusting the brakes on our 20-foot trailer — going through the brake adjustment process step by step so the trailer brakes properly before towing season gets busy. Once the trailer brakes were set, I moved over to one of our Polaris RZR 800s that wouldn't start. I walk through the troubleshooting process on the RZR 800 — checking fuel delivery, looking at the fuel pump, and narrowing down why it won't fire up. By the end of this video I've diagnosed the issue and ordered the replacement fuel pump. The install and start-up test will be in a follow-up video, so subscribe if you want to see whether the new pump fixes it. If you're dealing with your own trailer brake adjustment or a Polaris RZR (or any UTV/side-by-side) that won't start, hopefully this troubleshooting process helps you narrow down your own issue. 🔧 Subscribe for more real people projects. #TrailerBrakes #PolarisRZR #UTVRepair 0:00 Intro – Trailer Brakes + RZR 800 No-Start 0:39 Adjusting the Trailer Brakes 20:15 Trailer Brakes Done 20:43 Moving to the RZR 800 25:32 RZR 800 Won't Start 44:33 Inspecting the Fuel Pump 49:36 Diagnosis: Likely Fuel Pump Failure 54:28 Ordering the Replacement Part and What's Next
