Will it keep running if you keep your foot on the accelerator pedal? If so I'd suspect a bad or dirty IAC (Idle Air Control) valve. HTH. -Jim

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

Ok, by what you're describing it sounds like either the key was worn out, bad fuel pump, or bad fuel pump relay. If the anti-theft module does not recognize the key it will shut down the ignition system and fuel pump (engine immobilizer). But the truck should recognize the second original key. Listen for the fuel pump. Turn the ignition to the run position but don't try to start it. You should hear the fuel pump run for about 3 seconds. The security light, on the dash, should go out within that time as well. If the fuel pump doesn't run but the security light goes out, replace the fuel pump relay. They're cheap. If the security light stays on it's going to be a security system problem. HTH. -Jim
