before spending big bucks on it, change the fuel filter and check the fuel lines.
replace it. You can get them at any auto parts store. Take the old one with you so that you can be sure that you get one with the right size intake outtake. Also if the fuel lines are original which they probably are, you should replace all of them including the pickup tube in the tank. While replacing the lines, switch the short one from the filter to the pump with the long one from the tank to the filter. This will allow you to have the filter sitting on top of the tank. This will make it much easier to replace the filter. Also, while doing this, you might want to take the tank out and clean it out. You will need to syphon out all the gas. You can't remove the tank with gas in it without spilling it everywhere. I washed it out with water, then poured a couple of ounces of Sea Foam in it, splash it around, and poured it out. I did the Sea Form part a couple of times. Every couple of tanks I run Sea Foam in the gas, 1 ounce per gallon of gas. You could run fuel injector cleaner instead.I am just going to order a new filter tonight like you said it’s over 10 years old, any recommendations where to get it from. Thanks
If what you say is true about the pump and filter being in the gas tank on your Rhino then ignore everything i said. My antique 04 660 is carbureted and had the old crappy rubber diaphragm fuel pump. Someone on here with the fuel injection system knowledge should answer shortly.Thanks for all that great information. I believe the pump and filter are in the gas tank. When I put in an in-line gas filter can I remove the gas filter that’s in the gas tank? Is there any way to check pump pressure or the injector? l think the pump should have at least 40 psi or over. Thanks again.
Thanks sandbuster, the fuel tank was drain every year and new fuel and stabil was added. I also drove it a little to get the new fuel into the injector. The fuel I drain out smelled good. I will remove the fuel line and check the fuel flow. Thanks for all that information and I will get back to you.
It could be as simple as a spark plug. Mine did this before and acted like a 2 stroke with a fouled plug. Changed the plug and it was good to go.
Thanks so much for the informatio, I will order a iridium spark plug today. I didn’t know it was a throttle body injection. I thought it was regular fuel injection my fault. I will install the spark plug when I get it and let you know if it clears up the problem. I am sure hoping it will. Thanks againFirst thing I would do is replace the plug and do so with an iridium for life. Understand this is not a real Fuel injection system. It is a throttle body injector similar to the original GM Rochester type things. It squirts and atomizes the gas in the throat of the throttle body depending on rpm and location of the crank by CPS. If the nozzle gets a ethanol fuel bogger or piece of trash in it it will do what you describe. Static fuel pressure will build and give it a squirt but residual pressure while running is not enough.
Thanks Jim for the information. The new iridium NGK spark plug just came in yesterday. I installed in and added some fuel injector cleaner to the gas, so far it’s running very good no stalling issue. The old spark plug was kind of black, it could be 4 or 5 years old. Thanks everybody for all the help, I keep you guys informed but I think it’s fixed. Thanks again
