[BrokeImpala]

I have a 2000 Impala with the 3.4 engine. It quit on my wife the other day and i've been trying to get it going again. So far I have replaced the fuel pump and the ignition switch with no sucess. There seems to be no power leaving the fuel pump relay to turn the pump on, but I can jump out the relay and make the pump run. It seems that when I do this there is no spark in the ignition. Is there a relay or sensor that controlls both...............open to any suggestions.
