They will not always prime if the preasure is already to it. check the preasure. Mine was still making the prime sound but was not putting out the right preasure so I had to replace it. If it is defective go back with one from GM or buy a good aftermarket one not a autozone (or other auto store special)because its a cheaper. Also there is a fuel pump relay under the hood too. just not sure where yours is but mine was on the firewall by the master cylinder.
