Hello, everyone. First time poster here. My father had a 2009 Rhino 700 that he bought a few months before he passed away two years ago. I have more experience with working on cars than ATVs, motorcycles, etc. It has been started off and on over the past few years but not too much extent. Recently, I have had struggles keeping it running. For the longest time, it would turn over but wouldn't start. I finally got it to start but it would die within a second or two. I started out with the simple things, draining the fuel and putting fresh gas in, replacing the plug, checking the air filter, etc. When that didn't help, I decided to replace the fuel pump because my research indicated that was a common issue. Now that I've done that, I do see an improvement. It will start and run for 15-20 seconds and then die again, struggle to start, and then repeat the cycle. I thought maybe the injectors were clogged so I ran a bit of injector cleaner through. It has been backfiring off and on during this process. At this point, I'm not sure what else I should be looking for. Any advice would be greatly appreciated!
