• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

No fuel pressure but fuel is flowing from tank. Also see movement in tank. 2013 Spyder Rs the regulator is at throttle body did the pinch test still no movement on gauge. Won’t start any help greatly appreciated.

Hey Junior. Stop me if this is already sorted out. I can’t recall ever hearing about a fuel pressure regulator failure on a 998 system, and maybe one fuel pump. But, anything can happen. So, just wondering how long this machine sat since it was last running, and is this your machine or are you working on it for someone. Usually, fuel pressure is not the first thing on the checklist for a no-start situation. What have you already looked at before this.

But, just to get back to basics. And please don’t take it personal if you’ve already covered it all: Fresh fuel, fuel system cleaner won’t hurt, fully charged battery, all fuses tested (not just looked at). The fuel pressure gauge needs to be “T’d” into the line between the fuel pump and the fuel filter. I suppose you can remove the fuel filter and place the T in its place. Under the circumstances, though, I think I’d want to leave the filter installed. But, it has to go in the pressure hose, between the pump and filter. The other hose to the fuel pump is the return line. It never has pressure in the 998 system. The fuel filter, the silver metallic thing is there behind the charcoal canister on the right side of the bike. The fuel pump only runs for three seconds when the engine isn’t running. It’s a timer from the ECM. It is easy to hear the pump running.

So, let’s try it like this. First, be sure that the gauge is hooked up in the correct section of fuel line. Then, put the kill switch to STOP. Then turn on the key, let the boot up process finish, and acknowledge the safety card screen with the Mode button. Even if the screen doesn’t appear, press the Mode button anyway. Get your head down by the fuel tank and position the gauge where you can see it, reach up and flip the kill switch to RUN. You should hear the pump run and hopefully see pressure on the gauge. You have three seconds-ish and then the pump will shut off. What do you got?
