Truck starts then dies please help

[svtlightning95]

So I just bought a wrecked lightning that runs and drives, drove it into the garage and pulled apart the front clip and removed the radiatior support, now the truck will start but shut off immediately, I've checked all the usual stuff but it just dosent make any sense and help would be greatly appreciated.

maybe you damaged or cut a sensor some place when you removed the front clip ??

What year is this truck ? .
You probably have a ground off , since you said that you removed the front clip .

 

[svtlightning95]

It's an 01 , all grounds are hooked back up.

Maybe it is not related to the work you did, try replacing the fuel relay with another. It is not uncommon for them to fail. Are your gauges sweeping each time you start? Is the theft indicator light flashing?

I switched out the relay with a new one from ford, and the gauges sweep normally, theft light goes off like it's supposed too. It dosent have good pressure at the shrader valve, going to put a gauge on it this evening

Did you unplug the fuel pump resistor (for speed control) below the radiator?

Update, ended up being the resistor. Thanks for everyone's input!
