Ok yes. No power back to the fuel pump. Usually the connectors go bad, either need to be cleaned or replaced. Use a test light for check power. Relays are another thing, may just want to replace.

Rowefast ..will secutry disable the fuel pump ...when the key is out of switch security light flashes steadly ..when key is in with switch on postion it does not ...when trying to start it will flash again ...I heard about the pass lock or something ...new fuel pump and non working pump ..

Yes possible something with the security. Unfortunately I only know how to turn them on and off with the FOB. If it is activated, the pump will not run.

I see you posted a new question, good. I won't respond so somebody who know security will respond.
