There is a small transistor in the ECM that drives the fuel pump relay. It is common for them to pop. I use a 2N2907 or a PN2907 transistor to replace them.

Hi is that transistor located inside the ecm ? Where can I buy that part ? I check the fuel pump the relay is new and I put a switch to feed that dark green/white wire and it runs but I want to fix it the right way thank you for replaying me back

Electronics store for the transistor. The PN2907 is easier to get and is a plastic cased unit.

Arrow points to the one that usually fails. Note that GM also used a fully plastic one in that location. Such as the one to the right of it but taller.
