I had exactly the same problem, fuel in the tank, FPC bypassed and pump running but still no joy. Put a new FPC in and it fired up straight away!

Don't suppose the pump is running.....backwards?

Tried that, no difference only in sound. The only thing that I could think of was that as I was powering it off an accessory socket (none OEM) then maybe it was a lower power supply than it needed.

Could be: When I had to do it, powered it straight (but fused) off the battery.

How Bizarre.

When my FPC failed, I double-checked my diagnosis by running a power supply straight from the battery terminals to the two pins of the fuel pump internal socket.

Pump whirred, bike started no probs.

Then with my home-made 'get home' cable made from the old FPC connector, I tested it using the din plug socket (pump tripped it out in about 30 secs) and across the battery terminals (pump ran continuously, so did the engine).

ISTR that there was a thread on exactly this a week or two ago...probably involving that nice Mr Wapping gentleman.

would be worth having a good dig around using 'controller ' etc against 'wapping' in the advanced search function.
