Code P0301 indicates a misfire in cylinder 1 of your 1996 Toyota Corolla 1.6L1. The most common causes of this issue are faulty spark plugs, worn-out spark plug coil packs, or faulty ignition system 123. You mentioned that you have already replaced the spark plugs, spark plug wires, distributor cap, and rotor button. However, it is possible that the new parts you installed are faulty or not installed correctly. You may want to double-check that the spark plugs are gapped correctly and that the spark plug wires are connected to the correct spark plugs
Code P0401 indicates a problem with the exhaust gas recirculation (EGR) system . The EGR system is responsible for reducing the amount of nitrogen oxide (NOx) emissions from the engine. The most common causes of this issue are a faulty EGR valve, clogged EGR passages, or a malfunctioning EGR vacuum modulator . Since you have already replaced the PCV valve, it is possible that the new part is faulty or not installed correctly. You may want to double-check that the PCV valve is installed correctly and that the EGR valve is functioning properly. If these two code problems persist, it is best to take your car to a trustworthy repair shop to diagnose the issue as quickly and accurately as possible .
The symptoms of a bad EGR Valve Control Solenoid in a 1996 Toyota Corolla 1.6L include rough idling or stalling, a smell of fuel, increased fuel consumption, pinging, tapping, or knocking sounds, failed smog test, and check engine light on . If you are experiencing any of these symptoms, it is recommended to get your vehicle checked by a professional mechanic.
In terms of DIY, you can try cleaning the solenoid valve with throttle body cleaner and then test the solenoid electronically with a 12-volt supply. If that doesn't work, you can replace the EGR valve, vacuum modulator, and VSV (if equipped) and clean out the carbon buildup to the intake from the EGR valve.
Please note that if you decide to drive the car without the EGR valve and the EGR Valve Solenoid working, you can keep cancelling the code. The ECM will try and work things out and compensate. However, it is not recommended to bypass the EGR valve .
You have to make sure it has spark plugs and a fuel pump and must work well. Reset Security System and engine immobilizer. Check for Diagnostic Trouble Codes.

It seems like you have already checked most of the common causes of a non-starting engine. However, there are still a few things you can try:
Check the fuel system: Make sure that the fuel pump is working properly and that there is fuel in the tank. You can also check the fuel filter to see if it's clogged.
Check the battery: Even though you have two batteries, it's possible that one or both of them are not providing enough power to start the engine. You can have the batteries tested to make sure they are in good condition.
Check the glow plugs: If the glow plugs are not working properly, it can cause the engine to have trouble starting. You can have the glow plugs tested to see if they are functioning correctly.
Check the compression: If the engine has low compression, it can cause it to have trouble starting. You can have the compression tested to see if it's within the manufacturer's specifications.
If none of these suggestions work, it might be best to take your vehicle to a certified mechanic who can diagnose the issue more accurately.

If that finds nothing wrong, remove the EGR valve and bypass tube and check them for cleanliness and blockages. If they are blocked, follow your maintenance manual's instructions for cleaning them out so you do not damage the valve, then replace them and reset the ECM.
filter and pump are located in the gas tank. should be access to it under back seat of carl, in trunk or you have drop the tank. pull codes at autozone to make sure its not something else like injector or vacuum leak

It seems to me that there is an error in the system, you should contact the dealership. I've encountered several of these errors when I've been redoing everything on my car. I purchased tacoma rock sliders because I decided that this would be the best solution and at the same time corrected some errors like yours, so as not to get into an unpleasant situation when I am far from auto repair shops.
