ok so i think i have narrowed it down to a fuel pump problem on my bike. short version turn key on all the light work fuel pump doesn't turn on. all the grounds are good, and the battery it good and connections are tight. my question is how hard is it to replace? is it skinny enough to get out with out taking any thing else off? any help would be apreatiated. the fuel pump runs $359.25. and its part # is P0130.5A8. | ||

when i first got my bike, i thought the fuel pump was on it's way out, cuz it is so loud. turns out you gotta take off the swing arm to swap it out. pretty involved process. i'd troubleshoot for a long, longtime before ripping into it.... as would any reasonable person | ||

Did you see if the pump is getting any power to it? What model and year bike do you have? | ||

did you check your relays? If you have an XBR they will be on the left side of the instrument cluster. Switch em up and see if the pump comes on. | ||

+1 on checking the relay. If it's an XBS, they're under the seat. | ||

I have my pump out right now. I had two nicked wire grounding to 12 volt and insta popping my ign fuse upon turning the key on. I got fixed up good and I'm just waiting on some o-rings for reinstall. It's not too difficult. I suggest reading the service manual. This is just off the top of my head: First disconnect fuel pump from harness and start bike and let it run until it dies to remove pressure from fuel line. Now raise bike via jack under muffler. Remove rear wheel. Remove sprocket cover. Remove swingarm brace. Remove rear caliper and hang it up out of the way somewhere (I used my Ventura rack). Next, remove the rider peg mounts from frame. I tied the right side one up out of the way so I didn't have to disconnect any of the rear brake components. Next drain swing arm. Unscrew the three oil lines from the swingarm. Now remove lower shock mount bolt. Then loosen swingarm pivot shaft pinch bolt. Then remove pivot shaft (with that 7/8 nut thing from tool kit) and put the swingarm some where safe. Now you gotta drain the frame via the drain plug located in the fuel pump base plate. Then remove nut that holds fuel line onto fuel stud and pull fuel line off. Next step is removing the four fasteners (screws) that hold the pump inside the frame. Now the pump is ready to be removed from the frame. I strongly advise getting the Fuel pump puller tool. It's about 37 bucks but I think it would be worth it. I didn't use one and ended up munching up one of the large O-rings. (books says replace these any way.) Actually the book calls for new O-rings for the pump and for the fuel stud and a whole new drain plug/w o-ring. It took me about an hour to do all this. It was my first time and I bet I could do it all again in under 30 minutes now. On Edit: Now you know what's involved. I strongly suggest you make absolute sure the problem is the pump itself before embarking on this project and shelling out $360 for a new pump. I wonder if an extention harness could be made in order to hook your bike up to some one else's fuel pump just to see if their pump kicks on when you turn your bike on. It would eliminate a lot of guess work. (Message edited by metalstorm on June 06, 2008) | ||

you could hook a multimeter to the fuel pump harness after disconnecting it from the pump. turn on key look for voltage for 5-8 seconds. i thought that i could disconnect the fuel line to the injector and pump the fuel into a bucket. nope, only runs about 5-8 seconds on the 1125. kept repeating after siphoning until old fuel was gone. good luck. tim | ||

Diagnosis good. Parts shotgunning bad. | ||

so i checked the voltage at the plug for the fuel pump. got volts. checked the battery and all the grounds. all good. i also swapped relays around. relays good. still the fuel pump doesn't come on. so i ordered XB series trouble code dongle http://www.americansportbike.com/shoponline/ccp0-p rodshow/9016.html from American Sport bike. hopefully this will give me the correct code. and i will know what the problem is. |
