Hey, Im so confused and have no idea what I need to do with my truck lately. I really not want take to dealership. You know how pricely they are. Id not like to spend to much $ on dealership. FIrst of all about 2 weeks ago I went to track which is first time on my truck. Of course its 5.3 vortec. I did ran real low gas closer to E sometimes the orange light on the fuel gauge. about 4 times to race on the track. It was all fine lately. About one week later. When I stop by breakfast at chicken fila in the morning before I go work. It wont run at all. Sounds like no gas. But the tank is FULL! I went to open the hood and look at fuel rail to bleed. It was good bleed of gas out. Then I would tried to crank up its work.. I did switch fuel relay it does same thing. UNTIl yesterday when I was on way to home from work. My tank about half gas left. It seem tried to died while I was driving. I push some more gas to keep run. It was fine this time. Until I stop the sign. It died. I tried to crank up. It wont. for about 15 mintues finally run. I speed up to get home. So I arrived. I turn off and would see if they would run again. It wont run at all. I gave up. Then this morning Id try do again. It was fine. I drove to gas station to get fill up full gas. It wont run. I called my cousin come by and he can listen the fuel pump which i am DEAF lol. Wish I could hear but only able feel it. HE heard it make a noise the fuel pump. I thought that mean fuel pump still good? If no noise mean bad fuel pump? When he hear the noise I tried to crank. It wont. About few second it run finally. When we arrived home. It did same thing the damn problem. Tell me what exactly caused. Fuel pump? Crankshaft position? PCM bad? THat one Allen Nelson tuned my pcm. I was going to order walbro 255lph from him. But I rather find what a exactly before I buy it! My truck is ONLY 83k mileage its 5.3 regular cab. Hope anyone can give me some idea.
