2002 taurus 3.0L OHV stalls when hot have replaced IAC,camshaft position sensor,fuel pump and there are no codes on engine stall occurs most often when slowing and turning

Check the fuel supply. There may be a blockage in the fuel line or the air vent for the fuel tank is blocked.

Check your fuel pressure, can happen when a fuel pump is gonna go out

Did he clean the throttle body - plate . TPS - throttle position sensor . Check for vacuum leak ?

The most common reasons for stalling is a faulty throttle position sensor or low fuel pressure.

CHECK FUEL PRESSURE SOON AS ENGINE STALL OUT.IF FUEL PRESSURE SHOULD BE 41 - 47 PSI. IF NOT OR PRESSURE ZERO OR LOWER FUEL PUMP FAULTY.FIRST REPLACE FUEL PUMP RELAY AND CHANGE FUEL FILTER SEE IF ENGINE STILL STALL OUT.IF FUEL PRESSURE OKAY HAVE CAR CODE SCAN FOR FAULTY CRANKSHAFT SENSOR OR FAULTY CAMSHAFT SENSOR.

So..... you replaced the pump because it stalls, or it ran ok, and you replaced the pump and now it stalls? Stalls going 50 mph? idle? hot? cold? ck eng light on? codes? Fuel pressure?

a bad camshaft sensor will cause the engine to chug or stall, i would replace that first.

Most likely Idle air control valve fault. Usually wont set a code unless it has a short or unplugged. There are some test that can be performed with a high end scanner but with out the data not much you can do.

your evaprative emissions could be purging into the engine at that point too, giving too rich a mixture.

here's what you are referring to:

ISSUE: A reduced power, hesitation, stalling at low vehicle speed, idling and/or a no start condition may occur on some vehicles in hot ambient temperatures and/or high altitudes. In addition, a no start may result while the engine is still hot and the vehicle has been parked for a short period. A stall may also occur when moving the vehicle from idle. This may be caused by a lack of vapor ports in the fuel pump, resulting in a vapor lock condition or internal high wear of the fuel pump components due to tank contaminants.
ACTION: Perform normal diagnostic routines as described in the appropriate year Powertrain Control/Emissions Diagnosis Manual (PC/ED). If the condition still exists after all diagnostics are followed, replace the fuel pump with a new turbine fuel pump. Refer to the following Part Application Chart for correct part usage. Also, replace in-line fuel filter with a new filter (E7DZ-9155-A). The new turbine fuel pump will reduce the possibility of vapor lock in high ambient temperatures. Refer to the appropriate model/year Service Manual for removal and installation procedures.

1st thing change fuel filter. You probably pulled in some crud from the bottom of the tank. countrycurt0
