The P0171 means System too Lean (Bank 1) and the P0174 means System too Lean (Bank 2). Hope it can help you!

Clean the mass air flow sensor with brake cleaner spray. Throw away the K & N filter if you have one installed. Both are common causes that set a P0171

i had same problem.u have to press step untill miles to service then press reset for 3 seconds . hope it helps

Check the injector for proper voltage. Check the cam sensor,,,,,DO NOT remove it unless you index it to the block. generally, a malfunction of the sensor will affect all cylinders, PS: you did check to make sure there is adequate spark at #1 plug, right?

Sounds like you have a vacuum leak for the lean code and the misfires. I don't see a 473 code in my manual, but have a 463. The 463 is for the fuel level sensor open or voltage high.

If the data link is not talking to the computer check your ground at the computer and at the data link connector to see if the computer is even alive ground pin 3 on DLC with the key off then turn key to the run position if it flashes the check engine codes record them, if no engine light, does the engine light come on when you turn the key on then go off? if not, check fuses if not check power for pin on computer, if it has power you have a bad computer. But TEST THE GROUNDS IT IS THE BIGGEST FAILURE For these rigs or any manufacture. check that you have power also at the DLC too. if not you need a digital ohm meter and a subscription to http:///.www.alldatadiy.com and start reading the campaigns on that vechile for computer and trouble tree for dead DLC and computer. I don't have that subscription or I could tell you more where to look, if you need anymore help let me know. Also if the crank sensor could cause it not to run the fuel pump but so can the cam sensor. You need to find out if the computer gets it's pulse for the pump at the computer if it does then you need to test them both. There are three wires a ground a colored power wire and a wire to go to the computer you can test these sensors with a meter to see if there is a pulse to each. sometimes the fuel pump gets it's signal from the coil pack so it's important to have the subscription, you can do a search for each item and test them as needed and has a wiring diagram.
Hello
When the service engine
soon light (Also called the check engine light or engine management
light) is turned on this is to alert you to the fact that Powertrain
Control Module (computer) has detected a failure somewhere in the
systems it controls you may not feel any difference in the way the
engine runs, this can be the transmission or the engine or emission
system, there are fault codes set in the modules memory for these
faults. What needs to happen now is to have the powertrain control
module scanned with a special tool called an OBD2 electronic engine
control scanner or a OBD2 code reader. Once the code(s) are read then
you must perform the diagnostics for each code and make the
appropriate repairs based on the findings of the diagnosis that was
performed, this is called doing "Pinpoint" testing.

Found the solution after changing the coil pack and new plugs which didnt solve the problem it was the fuel pump.
