Had my car fixed, put 2 fuel sensors in and a new battery. My engine light was on and now its off.... but it wont go through inspection. It keeps saying not ready. I've driven it 225 miles to try to gt it to click in, but it won't. The obd moniter readiness status reads: catalayst (G)/NMH Catalyst (D) not ready, Evoaprative System (G)/ unsuppoted (D) Not ready, and EGR/VVT (GD) Not ready... My car is running great and the engine light is out, and no other lights are on.... What do I do?

I can think of a few thing's that could cause this , a mass air flow sensor, crankshaft position sensor , coolant temp sensor. If the check engine light comes on there should be a DTC - diagnostic trouble code stored in the PCM - engine computer ! I'd find a parts that will check for codes an go from there . unless you have a factory scan tool that will check engine data parameters !
Hard Start
Inspection/Test
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 .
• Search for bulletins.

Sensor/System
• Inspect the engine coolant temperature (ECT) sensor for being shifted in value. Install the scan tool and compare the displayed engine coolant temperature with the intake air temperature on a cold engine. Check the resistance of the ECT sensor if the engine coolant temperature is not within ±3°C (5°F) of intake air temperature (IAT). Refer to Temperature Versus Resistance . If the ECT sensor resistance is not within the specification, refer to DTC P0117 or DTC P0118 .
• Inspect the mass air flow (MAF) sensor and connections.
• Inspect the operation of the idle air control (IAC) valve. Refer to Idle Air Control (IAC) System Diagnosis
• Using the scan tool, monitor the throttle position (TP) sensor voltage. The TP sensor voltage should be less than 0.9 volts with a closed throttle. If the TP sensor voltage is more than 0.9 volts, inspect the throttle body and accelerator cables for binding.
• Inspect for the proper operation of the exhaust gas recirculation (EGR) system. Refer to Exhaust Gas Recirculation (EGR) System Description

Fuel System
• Inspect the operation of the fuel pump. The pump should turn ON for approximately 2 seconds when the ignition is turned ON. Refer to Fuel Pump Electrical Circuit Diagnosis
• Inspect for incorrect fuel pressure. Refer to Fuel System Diagnosis .
• Inspect the fuel injectors and related fuses. Refer to Fuel Injector Solenoid Coil Test , and Fuel Injector Balance Test with Tech 2 or Fuel Injector Balance Test with Special Tool .
• Test for fuel contamination. Refer to Alcohol/Contaminants-in-Fuel Diagnosis .

Ignition System
• Inspect the operation of crankshaft position (CKP) sensors A and B.
• Test for proper ignition voltage output using the J 26792 Spark Tester .
• Inspect for damaged ignition coils within the ignition coil module assemblies.
• Inspect for damaged or misaligned spark plug boots.
• Inspect for a missing or damaged ignition module ground spring.
• Inspect the spark plugs. Refer to Spark Plug Inspection .

Engine Mechanical
• Excessive oil in combustion chamber-leaking valve seals. Refer to Oil Consumption Diagnosis in Engine Mechanical 4.6L.
• Inspect for low cylinder compression. Refer to Engine Compression Test in Engine Mechanical 4.6L.
• Inspect the following for incorrect or damaged basic engine parts:
- Cylinder heads
- Camshaft and valve train components
- Pistons, and piston assemblies

Recommend replace fuel rail pressure sensor, make sure connector and wiring are good, clear codes and recheck.

That is a good question but the answer is POSSIBLE but generally NO... and I will explain why

O2 Sensors read the amount of Unburned fuel in the Exhaust and sends the readings back to the Computer. So the computer gets the readings from BEFORE and AFTER the Catalytic converter and "METERS" the amount of fuel it puts into the engine.

The Timing Belt is what keeps the CRANKSHAFT and CAMSHAFT in perfect harmony so that Valves open and Close at the right time. Spark Plugs are firing the Fuel at precisely the right time... All the Orchestra is done by the Timing Belt.

Now, if the Timing Belt was installed improperly (which is VERY EASY TO DO), you would notice a slight sluggish or poorly running engine. Your engine will run being 2-3 teeth off. But you would notice it being off by the way it runs

So can it effect the O2 Sensor? It could but not normally if your car is running properly

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

You need to read the codes that your check engine light is showing. Go to Autozone or any place like that and they can read the codes for free. Throwing parts at a car doesn't fix it but finding the source of the problem and then repairing as necessary will allow for better results. Going off the check engine light being on can mean it is anything.

You have two O2 sensors on your car. One just after the head on the header. This is the O2 sensor that tells the PCM what the air/fuel is and the PCM can adjust accordingly. The one BEHIND the catalytic converter (or cat for short) does nothing but tell the PCM that the cat. is working properly. You may be changing the wrong O2 sensor. Also the EGR could be an electrical problem if that is the cause of the emissions failure.

So to review, find out the codes, post back with the codes and everything can go from there.

1. This is if it is an internal filter, if it is not you still have to pull the whole bottom of the back seat out and look for the inspection plate.
   
2. Relieve the fuel system pressure by first removing the fuel pump fuse. Then, start the engine and allow it to run until it stalls. Crank the engine for 2 to 3 seconds to release the pressure Turn the ignition off.
   
3. Step 2 Disconnect the negative battery cable. Remove the rear seat bottom and the inspection hole cover. Disconnect the electrical and quick connectors and remove the six screws. Remove the fuel level sensor unit and the fuel pump assembly. Then, take out the flange and snap fit portion of the fuel pump.
   
4. Step 3 Remove the fuel tank temperature sensor harness, the fuel level sensor flange, and the fuel pump connector. Disconnect the quick connectors from the fuel level sensor, and remove the fuel level sensor from the chamber. Take out the fuel filter.
   
5. Step 4 Put the new fuel filter in the chamber, followed by the fuel level sensor. Attach the quick connectors to the fuel sensor. Connect the fuel pump connector and put the fuel level sensor flange and fuel tank temperature sensor harness back.
   
6. Step 5 Place the fuel pump assembly inside the tank. Replace the screws and electrical connectors. Reattach the quick connectors. Reconnect the negative battery cable.
   
7. Step 6 Start your car and check for leaks, and make repairs if necessary. When repairs are complete, replace the inspection hole cover and the rear seat bottom.

When you changed the Battery you likely have "erased" the computers memory and the security system I might try locking all the doors and opening them with the key, see the security system shuts off the fuel injectors and even though you have spark and fuel at the rail the injectors are not allowing fuel to the cylinders.
You can confirm this by spraying some carb cleaner into the air intake and crank it over see if it tries to start. This will tell you if its a fuel problem for sure.
