How are you checking it? It only powers for 2 seconds when the key is first turned on so you need 2 people to check it.

when i do turn the key on it doesnt do anything but when i put power straight to the relay it works and also when i put power straight to the fuel pump it comes on too i think there may b a problem in the relay/fuse panel under the hood

would it b a problem if my o2 sensor is bad i know that it is bad because i put an air/fuel ratio gauge on it and the bar jkumps from rich to lean 2xs a second

It's supposed to jump rich to lean to rich, the faster the better.
