Ok go look under the hood on the driver's side for a blk fuse block and locate the fuel pump relay.You can either jump it or swao it with any other relay of the same design and try that.I'll give you a pick of it's location and should be labeled under the cover. If you check the terminals that the relay sit in one should be hot all the time and one will energize when key turned on
