Gauges Not Working!

[edbar 6]

My fuel gauge isnt registering any fuel even though I have put four gallons in tonight! The light has gone out but still says empty on the gauge. Any ideas? Sender unit?

Also I have trying to get the revcounter to work with my alpha management but no luck, the alpha system requires the tacho feed to join to in order for it all to work. On my 309 it was two of the wires off the original coil. so I have tried the same off the tu coil plug but no joy, fuses are fine and i've tried every combo of wires.

Here is the plug..

 

 

and the wires( yellow one is from the ecu )

 

Any help would be appreciated as I have mallory park booked for a Trackday on the 13 of feb and would like an idea what the engine is doing.

Got to try water temp and oil yet.
