Re: 2000 gtp wont idle
It could be your fuel pressure regulator? Pull off the vacuum hose and see if you smell gasoline fumes or if gas comes out of the vacuum hose. But with the pressure bleeding down like it is also could be fuel leak. Do you smell any gasoline fumes.

You may have a bad fuel pump resistor. There is a proceedure in our tips and maintenance sub-forum on how to bypass it to test.
