Here goes. This is my first attempt at a forum and asking for help. I have a 2004 3.9l. It starts acting like its out of gas, stumbling and popping. I can turn it off and back on then runs good for very short distance. I was able to get home by doing this. The CEL comes on and the code is for the fuel pump driver module. I purchased a brand new one and cleared the code. Still have the same problem and code. Please give me an idea of what to look for. I figured it would be a bad fuel pump.
