they are correct, the fuel filter is in the fuel tank.
the most likely problem with your car, it sounds like, is the built in fuel pressure check valve in the fuel pump as failed, this causes start stall condition..

SOURCE: lexus es300 won't start
I had a similar experience just the other day, i stopped to get gas and turned the car off and when attempting to turn the car back on nothing would happen. Well, let me rephrase the lights inside and out would work as well as the ac and the radio. My initial train of thought was maybe it was the battery so i went and purchased a new battery which was around $100, I installed the new battery and the car still wouldn't start. Does your car make a clicking noise when you turn the inginition key or is it just silent? If it is silent, you might want to check to see if your starter has burned out. Luckly a friend of a friend does his own mechanical work and was able to remove and replace the starter for me. After the starter was replaced the car started right up and ran perfectly. Not sure where u live but in my area a starter ranges in price from $100-200, but they also charge a core fee ranging from $45+, which can be reimbursed if you bring in your old starter to the store. I would suggest getting a starter with a lifetime warranty as well, but thats just a suggestion.
Hope this helps,

#4 Miss-fire. All the things you are saying make a lot of sense. When the light is blinking the cylinder is actualy misfiring, & the smell you are smelling is the fuel that is not burning in the engine burning in the exahst. This can cause a lot of damage to the exausht if it is not repaired..
There is still a couple of things that need to be checked, first he needs to check to see if it is possibly a fuel injector that is sticking. He can do this easily by moving the #4 injector to another cylinder & run the car. When it starts missfiring he will need to see if it is still #4 or if it is the cylinder that he moved the injector to. if it is the new cylinder it is obviously the injector, if it is still #4 he will need to look into the possibility of the EGR valve sticking open or some other issue to do with valve timing or low compression.
I hope this helps

I had the same problem. I thought it might have been fuel lines clogged or fuel injectors. It ended up being a vacuum leak. My vacuum lines came unhooked and the main had a big crack in it. Repaired the crack and hooked the lines up and the problem went away.

fuel filter is hardly ever been a problem with a lexus or toyota.you need to check for spark at the plugs.then go from there.
