2000 make RX300 won't start
basically the problem is that a 2000 make RX300 won't start. I mean from time to time if you let it stay for about 20-30 mins you might get lucky and will start but then at some point like 2nd time it won't. In service they thought of fuel pump and that system because one time when it didn't start they've hit over the pump area under the seat someplace and it started so they assumed there was something there. Ignition and battery/electric system seems ok. As for the fuel pump they've opened it looked at it filter seemed ok they've replaced some of the stuff and in general as they say this fuel pump seems ok but the car still does the trick
Please maybe some of you are aware of such a thing happening let me know what it might be
because for where I am at this point there are not a lot of experts here who really know this car
(despite the fact that it's not a rare model here)

Please read Having Problems sticky thread. Please elaborate on does not start.
Intermittent problems are hard to diagnose.
Fuel pump problem should manifest in driving as well. Did the mechanic perform pressure test and flow test of fuel pump? It is normal for a fuel pump to energize and cut out to maintain a certain pressure.
Also describe a bit of history as to when and how the problem started. Any work or service that triggered it. Was any electrical splicing that was done etc?

I'll make sure to check one more time Problems thread. But at this point I can confirm that the Timing belt was recently replaced and yes they've tested fuel pump by running pressure and flow tests everything seemed OK there. The battery works fine "it spins the starter well" and everything lights up normally on the panel. Now as for the a bit of background history this problem appeared at first rarely few times I mean every once in 4-5 weeks of then for the past few months it got more and more often twice a week and so on, so now (assuming generally 3-4 stars a day) first start in the morning is fine and the second one becomes a problem BUT if you leave the car for 40-60mins it starts back again normally as if something has "cooled down". There might be a problem with electrical splicing yes. And we've recently installed new set of Spark Plugs and might it be that electricity's not getting to Sparks despite the normally rolling starter?
Could it be something with Bendix or Commutator?

Well I'm browsing and unfortunately I can't find any situation for example in the problems section that would correspond to mine anyway's I'll try posting my questions there maybe someone else might find something to shed the light on this problem.

Does it crank and keep on cranking but not catch?
If so What if you press and hold the gas pedal 1/4?
Keep in mind you have to describe every detail when you describe a problem .. we are not there with you.

When it fails to start what does it do? Clicks, no click, slow spin of starter, fast and rapid spin?

Sorry for such a late respond I was waiting for Crankshaft Sensor to arrive. Anyways as you mentioned there where two things that could've caused this problem fuel delivery or a spark delivery issue and so far it turned out to have been the spark delivery problem. To be more precise Crankshaft Sensor wasn't delivering electricity to the sparks which logically caused this problem. Thank you very much for your replies. It really helped.

Glad things worked out.
Just out of curiosity, were you getting CEL and the code pointed to the offending sensor?
See if the following applied for you:
The starter is spinning the engine at good speed but it fails to catch. My CEL is on/ff.
Salim
Note: When you have problems, one is supposed to turn ignition to run and wait too see all self tests are complete. If every thing is good, the CEL light first turns ON and then OFF.

If it's intermittent, possibly starter contacts is the problem. Search for 'Denso Starter Contacts' and you will get the idea. You can buy the contact kit, and fix it yourself it that was the problem.
