When the fuel pressure regulator(1) on the 3.1 and 3.4
engine fails, fuel leaks into the vacuum hose at the top.
This condition causes a hard start, long crank time, runs
rough when started, and can also cause a stall condition
when coming to a stop.
This also causes poor fuel economy.
These pictures should help in the replacement of the
regulator.
NOTE: Relieve fuel pressure first.
