I have a 2001 Chevy s10 extreme with a 5.3 swap finished other than the gauges hooked up and the truck starts for one second then shuts off. I have one code. P0452. What could this be caused by?Actually I have 2 codes but the other one is P0405. It's for the EGR but I deleted it so don't think that has anything to do with it.
Can't figure this truck out...

It will run with o2 sensors unplugged it will just be in open loop. But you have to have vats off for it to run
What could be the fix or the reason that it is throwing the code P0452? It means fuel tank pressure low voltage. Cause the truck starts for about a second or two then shuts off. Any help is much appreciated. I'm just trying to finish this truck before I deploy and it's killing me.

Dont think the codes have anything to do with it. Like others said security which I know you said has been removed. Or who did the wiring. there is a wire that must have run and crank voltage. If it is just run voltage that means the fuel pump will shut off druing cranking. then it has just enought fuel to fire for a second and then dies, before the fuel catches up. basically what i am sayin is make sure your pump is staying on while cranking.
Well i bypassed the relay and and put 12 volts straight to the fuel pump. It still didn't want to stay running unless I use ether. I guess im going have to find a bypass module. Since its a swap and different computer, is it still possible to use a bypass module? Cause I have one sitting in my garage. It's the expresskit dball module.

How is it tuned? I had a car one time and it would start and die. Found out whoever tuned it made it run 100% off of mass air flow and nothing else. No VE tables at all. Found a bad wire going to the maf. Fixed the wire to the maf and it ran told him he needs to find a better tuner.
