There is an external fuel filter, if equipped is located on top of the fuel tank. Some models did not have an external fuel filter To test Fuel Pressure, .Raise vehicle on hoist, and disconnect the fuel pressure line at the fuel pump module. Install special 5/16 fuel line adapter tool #6539 between the disconnected fuel line and the fuel pump module.
Turn the ignition on. With the DRBIIIt, actuate the ASD Fuel System test and observe the fuel pressure gauge NOTE: Fuel pressure specification is 400 KPa +/- 34 KPa (58 psi +/- 5 psi).
P0171-FUEL SYSTEM 1/1 LEAN
When Monitored: With the engine running in closed loop mode, the ambient/battery temperature above 20°F(-7C) and altitude below 8500 ft.
Set Condition: If the PCM multiplies short term compensation by long term adaptive and a certain percentage is exceeded for two trips, a freeze frame is stored, the MIL illuminates and a trouble code is stored.

thank you for your answers, I could not find the external fuel filter, now the engine starts but when I step on the throttle the car hesitates like it needs more fuel but if I slowly step on the gas it is ok. I am going to buy the fuel line adapter and check the fuel volume and pressure. Thank you again
