i cant seem to get my fuel pump to work. i have an in-tank fuel pump with a return line. im in the process of a a TPI ->carb conversion and i think when i ripped the ecm out i may have cut the fuel pump wires. i tryed to apply positive battery voltage to the bottom left terminal on the ASDL and nothing happens. is my fuel pump toast? i cut every single wire that goes down into the passanger side pannel to the ecm. when i looked at the wires leading to the fuel pump, there is a purple, black and a grey wire going to it. does anyone here know what these wires do? im assumeing black means ground. what about purple and grey?

 

One is for the fuel gauge and the other is power to the pump.If I remember correctly,the grey is power and the purple is for the gauge,but like I said,I am not 100% sure. When I switched to carb,I powered the fuel pump to ignition.
Also,you didn't cut all the wires at once did you?

 

yeah, i cut all the wires at once. i realize i should have eliminated them one at a time, but my engine compartment was completely covered with wires, they were getting in my way. i got pissed off at them always getting in my way and sliced off everything that was going to the ecm. i figured the ecm would be useless anyways so any wire going to it would be useless aswell
