What is your question?
2001 Chevy Silverado 1500 Truck will start, sputters for a minute then stalls. Will restart and do the same thing over and over again. Have cleaned the MAF, replaced the fuel filter, disconected the MAF, nothing so far. Feels like a bad carborator (I know it doesn't have one.)Don't want to spend the money on the wrong part. Any suggestions? P0171 and P0174

Need to check fuel pressure, to be sure the pump is in good shape, because weak fuel pressure can set those codes. Those are 'fuel system too lean codes' bank 1 and bank 2. http://repairpal.com/OBD-II-Code-P0171-and-P0174 this is an article I wrote to help people with these codes, but first and foremost, check that fuel pressure!
