I have a 1994 dodge ram 1500 with the 5.9 and it runs rough at an idle and to get it started you have to floor it, once it is running it will idle but as soon as you put it in gear or just give it a little gas it dies. You can keep it running if you keep it at a high rpm. I have replaced the iac motor and the tps and cleaned the egr valve. I was checking the fuel pump wires and had it unpluged at the fuel tank and started it and it ran perfect, I could rev it up and it ran good but as soon as i pluged the wires back on to the sending unit it ran rough and back to the same prob. so I unpluged the fuel pump relay and same thing, runs perfect untile it runs out of gas, and when i plug the relay back in runs bad and you cant give it gas. No check engine light is on and I have no clue what to do from here. Please help
