I just replaced the fuel pump in my 06 Sebring Convertible yesterday. The car had trouble starting but ran fine. I checked the pressure with a tester & confirmed that the pump would not hold pressure. It bled-off as soon as the pump was energized and never reached specified pressure (approx 60 psi). I ordered a new Chrysler OEM pump assembly, removed the tank, & replaced the pump. I reinstalled the tank. I checked all the connections for leaks. There are no external fuel leaks.
Unfortunately the new pump exhibits the same symptoms as the original pump except the car starts fine now. It starts immediately no matter how long I leave the car sit in the off condition. But since the system isn't holding pressure I'm sure this is only temporary. The nature of the Chrysler fuel system is that there are only 2 places an internal leak can develop. In the pump assembly in the tank or in the injectors. Everything else is external. There are NO external leaks. No gasoline smell in or around the car. I REALLY don't want to remove this fuel tank again unless absolutely necessary.
Is it possible that an injector can cause the fuel pressure to bleed down immediately without any idle or driveability problems? As fast as this system loses pressure (2 - 3 seconds after pump is de-energized) implies a significant volume of fuel loss quickly. I can't believe I wouldn't smell this or suffer idle problems, or surging, missing, erratic acceleration, etc. But I have none of these things. Every fiber of my being tells me this new pump is defective & I loath to remove/replace this d#$! Thing again.
have the same problem?
