Run fault codes and check for cam/crank angle position sensor fault. Check that the cam shaft is turning over (broken cam belt) Check operation of the immobiliser and check that the fuel pump is still working.

that fuse feeds power to fuel pump relay circuit that feeds pump could be defective pump,or damaged circuit wires that shorts out! and not a good idea to put higher fuse in circuit could cause more damage to circuit! but i know when your stuck, u do what it takes,so inspect circuit related to fuse,

SOURCE: truck stalls while driving
check the throttle postion sensor and the idle air control valve sensor when they go out it will get to much air or to much fuel either one. and yes it will cause it to stall

You'll need to find out what code you have. There are lots of differant things that can cause a check engine light or a truck to run poorly.
For what it's worth sounds like a vaccume leak, maybe the egr. But you need to find out what the code if first!

When you are checking fuel pump voltage on your pickup when you turn on the key the voltage is only applied to the pump for a couple of seconds unless you go to cranking position.
There are 4 wires leading to the fuel pump on your truck. The gray wire is the 12 volt positive power feed to the fuel pump and the black provides the ground. The orange and purple wires are your fuel gauge wires.
The relay for the fuel pump is in your under hood fuse panel and I believe is marked on the underside of the fuse panel cover. It should click on and off again quickly when you turn the key to "on". Having a helper to cycle the key would be handy while you put your finger on the relay and listen to it. Just because it clicks still doesn't mean it's functional but relay failure on these models is somewhat rare.
I would start by checking for power at the fuel pump harness.
Fuel pump issues are quite common on these model year trucks.
Hope this helps you out.
