Question edited for clarity and the typos - Nissian, cyclinder, vam, and PO 304 is P-zero not P-letter Oh..

What makes you think it is the Crankshaft Sensor? This is a simple misfire on Cylinder 4. Check plug, leads and coil. Run some Injector cleaner.
The P0304 code stands for "Cylinder 4 Misfire Detected", which means your vehicle's cylinder 4 has misfired enough times for your powertrain control module (PCM) to notice. A worn spark plug, a faulty fuel injector, and a leaking valve are some possible causes of the P0304 code. Jul 28, 2023
Miss-fire on cylinder number 1. The picture shows location of cylinder number 1. Check for spark at number 1 cylinder. There are ignition based misfires--fuel based misfires--emission based misfires, I'm sure I'm leaving something out. You need to be aware the computer may disable the fuel injector if misfire detected on that cylinder, that's normal. Trying to protect the cat. If fuel injector is disabled have to decide if normal operation or something wrong with fuel injector or wiring circuit.
Believe it or not the firing order is 1-2-3-4-5-6 The cylinder locations are 2-4-6 in front by radiator, and 1-3-5 against the firewall. If you have a misfire on a certain cyl. and you've replaced the plugs,wires and cap and rotor, you probably have a fuel injector that's dead or plugged,it's common on Quests. Figure out which cyl. is misfiring and unplug the fuel inj. conn. with the engine running and listen for a change in RPMs. If there is no change then replace the injector.
P0300 - generic misfire.
P0301 - misfire at cylinder 1 = the spark was not generated at some time at cylinder 1 P1494 - Evap Leak Detection pump pressure switch condition = the ECM detected the leak detection pump switch did not change after the solenoid was energized P1495 - leak detection pump solenoid circuit = the electrical circuit that commands the solenoid of the pump is interrupted You need to check the wiring to the solenoid and the solenoid itself, located under the driver's side in the cast cradle under the steering gear. A good expertise of car electrics is required for that, you will need a good repair shop.
cylinder 1 misfire and low compression. Plugs and wires changed plus new fuel injectors. The engines still misses and no one can find the cause. When put on the computer it read misfire cylinder 1.
