Hello, for a crank but no start you must determine what's missing. Spark, fuel or air. With all that was changed I would think that spark and air are good. Although no spark could also be due to a bad relay or security key fob issue. Some security will cut spark some cut fuel. Check that your getting spark at plugs on both banks. If spark is present I would check fuel pressure and that the pump is working. A quick check would be to spray starter fluid in the intake after the filter temp install tube and crank. If it starts and runs rough and stalls I would check no fuel issue. Relay, fuse, pump. If all checks out make sure pump is getting 12v at harness at the pump. If not check wires. I've seen mice do bad things. Good luck!

Hi there,
There are several reasons for the "crank with no start" condition. Check this common causes:
1. A weak or almost depleted battery. It will not be able to provide enough voltage/power to start the engine.
2. Defective starter. The starter has a small starting gear that when you turn the key or press the engine start button, engages the engine's flywheel. Then, it delivers power, getting the engine rotating. If it is faulty, it will not be able to do it's task.
3. Faulty fuel pump or clogged fuel filter. Fuel may not reach the engine from the fuel tank if the pump is not operating 100%. The same thing is if the fuel filter is so clogged up by debris/dirt. The fuel from the tube lines would not be able to pass through and reach the fuel injectors.
4. Defective ignition switch. The switch turn on the electrical system of the car including the starter. If it is faulty, the starter would not be able to properly operate.
I hope this helps!
