My truck has been acting up for the past 3 weeks. It has been acting really sluggish and whenever i push the gas it hesitates for a little bit then finally goes down the road. I thought it was the lift pump because i got the code for transfer pump out of range. So i change it with a brandnew stock one and its getting about 20 psi of fuel pressure, but the issues didnt go away and the only way it will start is with ether. I will be driving down the road and it will just die on me. I have looked for every possible solution, Apps, Tps, ECU, vp circuit board, i havent tried any of these yet but i dont kow where to start, all of these are gonna cost me alot, so i would hate to be wrong and pay for something i dont need. I havent had time to put a code reader on my truck, i am going to do that this sat. Any info would be appreciated and considered. Please help me out!!
