2010 RS SE5 with 300 miles. Yes, actually less miles on it, but it won't start! Please help...

I do not want to upset anyone with a possible repeat, but I have researched this all over the web and I am not finding what I need to get this Spyder running. I bought this new and it has had the recall power steering unit changed, right after I got it. Then I drove it home and parked it in a climate controlled shop in my backyard, where it has been sitting for years. It looks showroom new. I have kept up with all the fluids, including draining the gas tank and refilling it several times.

About a year ago, I took an interest in getting it running, again, so I put in a fresh battery; drained and refilled the tank with fresh gas and a little Seafoam; I flushed out the fuel rail; replaced the main fuel filter; topped off the brake fluid and antifreeze; and proceeded to go through the start-up sequence. Turning the key on, the fuel pump pressurized the fuel rail; I heard the click of the fuel injectors; the brake was set; Neutral light was lit; I hit the mode switch; aaaannnnd, it cranked beautifully but would not fire. When I sprayed a little ether in both sides of the throttle body, it started and ran for an exciting moment, and then died.

I have been through all the fuses and relays; rechecked the battery and connections; and the brake switches. Nothing is rusted, corroded, or chewed. I have all the plastic removed so I can get to everything. I know its not getting fuel, but I am totally at the end of what I know. Please, does anyone have any idea as to what I am missing? Please respond, Thanks.

PS, I do have the factory manual...

I had checked the plugs a while back and they were dry and not fouled at the time, but I have done other things since, so I will check them again to see if that has changed. Another problem I am up against with the injectors, I would like to pull the fuel rail and the injectors, but even if the injectors are stuck or plugged, they no longer have injectors available for this motor. I might get by with a good cleaning of the injectors but another problem is they no longer have the fuel rail gaskets, so if the old ones get damaged, I am sunk. It's my own fault, I should have ridden it more or sold it. Does anyone know where I might find a set of the gaskets? Please let me know. Regardless, I will re-inspect the plugs for wet gas and get back to you.

I know there are ways to attempt FI cleaning without removing them. I will let you know how it goes, and thank you for your thoughts...

To @racoon, I thank you greatly for your time and effort. I am still going to try a non removal F-I cleaning but thinking about how long they have set, I believe they will have to be rebuilt or replaced. Thank you for giving me places to contact, and I would not hesitate to pull the injectors, not so much for the O-rings but my main concern is the fuel rail flat gaskets, (see photo exploded view ref #2). I would assume these two flat fuel rail gaskets, one on the left front and one on right rear of the throttle body would not be reusable and everywhere I have searched, I find they are no longer made or available. I will continue to work on this and will talk to the leads you have given me. I will continue to post how it goes. Thank you again.

I checked with the Tennessee FI service company, talked with Keith. He is very knowledgeable and assured me he could service what I had. So, I am going to concentrate more on finding or making the fuel rail gaskets. I also sent a plea to BRP, I hope they will offer some help for this as well. Regardless, I now have hope I can get it running and that feels good. Racoon, thanks again and a shout out to Cobranut as well. You guys helped me to think more outside the box. Don't know if you are following this, but I will post again as things progress... Thanks

Thank you, and yes, they are. I had researched this through a couple of Can-Am OEM parts suppliers and found that kit but at a ridiculously higher price with a very vague description. The price on the order list you sent is much more reasonable. I have been in touch with BRP, I was politely told they will not help, and suggested that I find a dealer in my area. After the help and advice of several here, I am now sure that I've found a suggested service place that will ultrasonically clean and test the injectors, and with what you just sent, I will once again pursue the Repair Venturi Device Kit.

I am going to take the advice of BRP and see if I can find a Spyder dealer who has the technical knowledge and can verify for sure that this kit has what I need. When I first bought this, honestly, I had a better knowledge of the Spyder than the young kids in their service departments. Not to overextend my welcome, but do any of you work with or know of a dealer in the USA who you trust with a good background in the Spyder world? Once again, thanks to all of you...

To Mikey, I understand where you are coming from, and many times what you said is how it goes, but let me tell you where I am with this. (Recap) I contacted BRP and they told me I would have to use a dealer, so I reached out to a dealer who did not have the parts I was looking for, but they also contacted BRP and were able to add to the story. The injectors are discontinued, but the rebuild gasket kit is still available, and on a list to be sent to the US from Canada, but it is caught up in the tariff issue with no release date. Someone from BRP did some research, and found a couple of dealers who should have them in stock. One was in California, they still had them on the shelf, and they checked to be sure. So, the gasket kit is paid for and on the way. Once I am sure the right gaskets are in this kit, I have a fuel injector service company that I talked with here, (thanks to Racoon), who said they can do what I need done to clean and test the original injectors. I will post progress as it happens, but again, thank you all for taking the time with this. I hope to have it running soon!
