No will not only way is if I feed gas into throttle body I'm thinking key might be not working right with passcode is this possible and if so would it be fixable

It's like gas is not getting to throttle body now a week before the security in dash light came on noticed my key was getting wore out changed to spare original key better not wore down worked fine down security reset 2 times still didn't clear read some were after one hundred cycles if nothing wrong would reset its self any way about 3 days before this happens. Security light in dash went out then this I'm trying to figure out a way to bypass it it acts like valves not opening to let gas through going to get pressure gauge tomorrow test pressure from new pump have also heard bunch of stories bad pumps out of box about to drive me crazy I have Addison's disease can't tolerate heat well so I have to hit and run any help thankful
