Get specs from two gauges.
If both are around 18 psi, you know that you must resolve that fuel problem. For sure!!
The 4.0 cannot run on 18 psi!

Well guys, I replaced the injectors and the fuel pump ballast resistor... And she runs like a champ. I really think it was the resistor cuz now the fuel pump makes noise while it runs. It never did before it. But oh well I'm not gonna argue now. Now it's time to go jump it
thanks for the help guys
