Williams wont start

[Alani]

Hi,
My Williams Turbojet 445 will not start, the fuel pump doesn't prime there fore will not start. Have by passed the kill switch and checked all the fuses and also hooked 12v straight to the pump and it still works. Any other suggestions on why my fuel pumps not getting the message?

Why not call Williams and ask them?

As above, but also working back from connecting directly to the pump, until it doesn't work should identify where the fault is. Sorry to be not a great help, but that's what I'd do. Be slightly wary of using a DVM, as it might show continuity, which could mislead you as it isn't (perhaps) able to allow enough current to run the pump through something like a poor or dry joint..

Gently use a hammer an klick onto the fuel pump while starting. If no result use DMV as mentioned above.

Throttle (bucket) in neutral position? Usually an interlock
