good advice. might be as simple as the ground on your starter loose\r\n

\r\n \r\n its def the fuel pump. ill get out there tomorow and see if there is any power getting to it. the bike turns over like a champ and i have tail light power, but no damn fuel pump\r\n

maybe ill check that out because it would crank all day when the fuel pump wasnt priming and then when i switched harness\' no crank but the fuel pump primed, i even put on ANOTHER harness just to see if for some odd reason the one i just put on was messed up and not letting it turn over.\r\n

jump the fuel pump and see if it primes to eliminate that from the problem cause they sometimes will take a shit. its really good to have a manuel and a volt meter in these types of situations because you can narrow the problem down quick\r\n

lame ass question but how do you jump the fuel pump?\r\n

[my750]

\r\n \r\n ima check the relay as well\r\n

[my750]

\r\n \r\n alright heres an update. took fuel pump off and everything looks fine with wires. i put a volt meter where it connects to the harness and got voltage. then five minutes later i did the same thing and got no power to the fuel pump. the fuck? and relays are fine as well\r\n

\r\n \r\n I\'m pretty sure there is only power to the pump when u first flip the key on and then when the engine is cranking/running\r\n

ahh good info my friend. i need some serious help becuase im completely lost. \r\n

\r\n \r\n try bump starting it(couldnt hurt). Last spring mine wouldn\'t start but the fuel pump would prime, lights on, sounded like it was turning over.

\nI thinks somthing in the starter had just frozen because I bump started it on the first try, and whatever was wrong fixed itself. I could start it normally after that.\r\n
