f4i no prime or spark???? help! - Blizzle - 08-13-2026
\r\n \r\n Im having a similar situation with mine right now but its not even cranking. The first time I had no prime it was a blown fuse in starter solenoind. The solenoid is located near the battery. After that it melted & melted the diodes in fuse box. I found my harness was melted by the radiator so I got a whole new harness with fuse box, relays & everything. Now Im thinking its my ignition.
\n So check the starter solenoid. Thats all I can tell u cuz Im in the same boat...Good luck!\r\n

\r\n \r\n Wouldnt it keep it from turning over if the starter solenoid was bad or had a blown fuse? It turns over fine just no fuel or spark.\r\n

\r\n \r\n ...my pump wouldnt prime(bike turned over,but no prime from pump) ) because there r two plugs that r identical and will plug into each other...check the plug that comes from the left handle bar switch. theres another plug from the harness thats identical,...switch the plugs....once i did that my fuel pump came on and bike crank...\r\n

\r\n \r\n If its the front relay its good. Does anyone kno if there will be voltage at the tip over sensor cause I\'m not getting anything at the red and green wire. I did connect them to get rid of the tip sensor\r\n

\r\n \r\n Just checked voltage on rear relay. Both blacks have 12v the brown black has 12v and the solid brown OS making a good ground??? And the voltage at the fuel pump is 9.6 when I turn the key and it slowely drops to 5.1 does this sound right? I don\'t get how only the front relay is clicking and the rear isn\'t even tho it has juice. And how the fp is not running unless I jump it off the black wires\r\n

\r\n \r\n Get a light tester connect to the ground and check all the wires again. I did that to my bike I was checking all the wires and one I touched one with ground from the battery my fuel pump starting priming and the bike turned on.\r\n
