Hey all I have a ninja 636 with the F1 light flashing, code 35 something to do with the immobiliser amplifier fuel pump won’t prime so non start, recently tried another amplifier but still no priming, the bikes stripped right down and cleaned some of the connectors as were a bit corroded but still nothing, at a complete loose end with it now, but does seem a common fault with the immobiliser amplifier, has anyone had the same fault and if so what did you do please,

also so just before it completely died it cut out on me twice mid corner it’s a 05 plate

thanks in advance
