Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** what you are telling me it can indeed be a fuel system issue. If the fuel pressure is not holding when the vehicle is turned off then this will occur. Most of the time it is the fuel pump, but it can also be a regulator or injector. I usually install a pressure tester and see if the fuel pressure holds or not. If it drops off over time then there is a problem. If not then it can have an issue with the shut down relay, ignition switch or possibly the crank position sensor. I hope this helps. Please let me know if you need anything else.
It is possible. If you had the pump replaced it could definitely be defective. If you wanted to do this yourself you would need to get a fuel pressure tester and then make sure it has the right adapters to install it onto the fuel rail of the vehicle.
