hey all

thanx in advance for the replys.

the car is an 89 firebird, original TBI, now carbeurated.

I had to rewire the pump, so basically I ran a hot lead to a toggle switch, to the pump. and the nevative off the pump to the negative on the battery.
but the gauge didnt work.

now,the pump has died, so I am using a Holley external pump.

So how the heck do I get the gauge to work, I have tried hooking everything back up,but it still doesent work.

The gauge should have (3) connectors. One positive, one negitive, one sender.
After you've checked that the pos. & neg, are present you'll need to verify that the sender wire from the tank float to the gauge is not compermized.

Does the gauge peg beyond full ? If it does then you have an open, since the gauge only reads between 0 (Empty) - 90 (Full) ohms. If you have an open circiut the ohms would be greater then 90 there by pegging the gauge.

If its stuck on empty, then check the pos & neg wires, disconnect the sender wire, does it do like mentioned above ? If nothing can get it to move, you may have sent 12 volts down the sender wire by accident, which = gauge death.
