CHANGED THE FUEL PUMP,THE FUEL FILTER,THE O2 SENSOR,THE SPARK PLUGS,THE ECT SENSOR, THE IAT SENSOR, NEW FUEL PUMP FUSE, BUT IT DOES NOT WANT TO CRANK

This problem can be hard to track down , it could be caused by several thing's ! A bad check valve in the fuel pump letting fuel drain back into the tank , not keeping fuel line pressure up , a crankshaft position sensor can also cause this as well as an ignition control module !
Checks
Action
DEFINITION: Engine cranks OK, but does not start for a long time. Does eventually run, or may start but immediately dies.
Preliminary
?€¢
Refer to Important Preliminary Checks Before Starting in Symptoms - Engine Controls .

?€¢
Inspect the powertrain control module (PCM) grounds for being clean, tight, and in the proper locations. Refer to Engine Controls Schematics .

?€¢
Search for bulletins.

Sensor/System
?€¢
Test the engine coolant temperature (ECT) sensor for being shifted in value. Connect a scan tool. Compare the engine coolant temperature against the intake air temperature (IAT) on a cold engine. The ECT and IAT sensor values should be within ?± 3?°C (5?°F) of each other. If the ECT sensor is out of range with the IAT sensor, check the resistance of the ECT sensor. Refer to Temperature Versus Resistance for resistance specifications. Replace the ECT sensor if the resistance is not within the specification. If the sensor is within the specification, repair the ECT signal circuit for high resistance.

?€¢
Inspect the mass air flow (MAF) sensor installation. A MAF sensor that is incorrectly installed may cause a hard start. Important: The embossed arrows on the MAF sensor indicate the direction of the intake air flow. The arrows must point toward the engine. Install the MAF in the proper direction. Refer to Mass Airflow Sensor/Intake Air Temperature Sensor Replacement .

?€¢
Inspect the camshaft position (CMP) sensor for proper mounting and/or a bad connection. A long crank time occurs if the PCM does not receive a CMP signal.

Fuel System
?€¢
Inspect the fuel pump relay operation. The fuel pump should turn ON for 2 seconds when you turn ON the ignition. Refer to Fuel Pump Electrical Circuit Diagnosis .

?€¢
A faulty in-tank fuel pump check valve allows the fuel in the lines to drain back to the tank after the engine stops. Refer to Fuel System Diagnosis .

?€¢
Inspect both injector fuses for being open. An open injector fuse causes four injectors and four ignition coils not to operate. Replace the fuse. Inspect the injector circuits and the ignition coil circuits for an intermittent short to ground.

?€¢
Inspect for incorrect fuel pressure. Refer to Fuel System Diagnosis .

?€¢
Inspect for a restricted fuel filter. Refer to Fuel System Diagnosis .

?€¢
Inspect for a contaminated fuel condition. Refer to Alcohol/Contaminants-in-Fuel Diagnosis .

Ignition System
?€¢
Test both injector fuses for being open. An open injector fuse causes four ignition coils and four injectors not to operate. Replace the fuse. Inspect the ignition coil circuits and the injector circuits for an intermittent short to ground.

?€¢
Inspect for proper ignition voltage output with J 26792 Spark Tester. Refer to Electronic Ignition (EI) System Diagnosis .

?€¢
Remove the spark plugs and check for the following:

-
Correct heat range

-
Wet plugs

-
Cracks

-
Wear

-
Improper gap

-
Burned electrodes

-
Heavy deposits

Refer to Spark Plug Inspection in Engine Electrical.
?€¢
Determine the cause of the fouling before replacing the spark plugs if the spark plugs are gas, coolant, or oil fouled. Refer to DTC P0172 or P0175 for diagnosis of the rich condition. Refer to Spark Plug Inspection in Engine Electrical for diagnosis of coolant or oil fouled spark plugs.

?€¢
Inspect for bare or shorted ignition wires.

?€¢
Inspect for loose ignition coil grounds. Refer to Electronic Ignition (EI) System Diagnosis .

hello good day, reverse your air filter, make the bottom to top,, if is not work change the high tension wires

Trouble Code: P0172

Fuel System Rich (Bank 1)

Possible Causes:


Base engine "mechanical" fault affecting one or more cylindersEVAP system component has failed or canister fuel saturatedFuel control sensor is out of calibration (i.e., ECT, IAT or MAP)Fuel system supplying too much fuel at idle speed or at cruiseFuel injector(s) is leaking or stuck partially open (one or more)HO2S is contaminated, deteriorated or it has failed.Ok Rusty,your mission is to figure and fix,got to go to work in the morning,good luck,this message will self distruct when repair is made.

Definitley NOT an O2 sensor(they don't even do anything for the startup).What happens if you shoot some starting fluid in it?

is the your car engine cranking when you try to start, first check spark plugs ignition coils, remove one ignition coil and spark plug fix the spark plug in to the ignition coil then connect ignition coil to wiring and keep spark plug body touching on ground of engine head mettle parts, ask some one to crank engine then you can see is the plug sparking or not, do the same way to all the coils and plug otherwise you have to buy a ignition spark tester, is the all the coils and spark plugs are OK then check the fuel pump, it's sitting in under rear seat, before that do one thing disconnect oxygen (O2) sensor wiring and crank engine, the thing is if your oxygen sensor completely dead fuel pump will stop working, if engine start after disconnect O2 sensor, replace new O2 sensor, otherwise need to check fuel pump relay fuse and fuel pump. is this information helped you? please vote me and give a comment.

Replace the coil pack.

Replace the coil pack..

i would check the fuel pressure first if it is in the good ranges then your pump is good. have you checked your spark plugs and wires? if not i would, if bad replace. otherwise i would have the ignition coils checked to find out if they are working correctly. that is all i can think of. good luck
