when you turn the key switch to on,not start,you should hear the fuel pump prime(humm) for 2 seconds and then turns off.it will do this every time you turn key to run.if it does not prime(humm),it ain't starting.you need to check/replace the fuel pump fuse and the fuel pump relay.you are not getting fuel to the engine.you also have fusible links coming off the starter and firewall.check them also,one of them may be burnt.if so replace with same size fuse link.
you have to have 3 things before the engine will run.spark,fuel/air,compression!you already said you are getting spark.you said it will start and run if you pour gas in the throttle,but cuts off.so,did you check the fuel pump fuse and relay?you need to check for spark again,you need to check the fuel pressure also.and tell whoever told you to replace the crankshaft position sensor to show you where it is.there may be an old one in the back of your vehicle but it don't belong to your vehicle,because your truck DON'T HAVE ONE ON IT!!the ignition control module are bad to go out on this vehicle,have it checked.take it to autozone,they test for free!check fuel pressure also.
