Turning over and cranking are the same thing. Starting or firing is what your Lexus is not doing.

Tow it to a Lexus dealership. They have the electronic diagnostics to find which of the hundreds of parts that could cause this has failed. Correct diagnosis is the key, and you replaced two parts that probably didn't need changing as it still doesn't work. To check the fuel pump, you put a pressure gauge on the fuel rail and turn the car over, then compare the pressure on the gauge with the nominal pressures mentioned in the workshop manual. One faulty coil pack would not cause your engine not to start.

My ES330 has had all of its 8 month services at the Lexus dealership since 2007.

Engine died while driving on the freeway, now only cranks but wont turn over/


As with any no start problem, have you checked for spark at the plugs and normal fuel pressure at the injectors ?
Does it crank with normal compression ?

You have to have adequate fuel pressure to start your motor and for your motor to keep started and run efficiently I would check your fuel pump I had a 2000 Lexus LS400 I had to replace the fuel pump

1995 Lexus LS400. Car was left in garage for two weeks while we were on vacation. Upon return it won't start. Engine does turn over. Replaced fuel pump in attempt to troubleshoot. Mechanic ha


I assume the pump was replaced because it was getting power but no fuel pressure ?
Are you still not getting fuel pressure ?
Spark to the plugs ?
Normal compression when cranking the engine ?
Security light not staying on ?

Will not start (no fuel pressure)


put your emergency brake on, in park, foot on brake, and have someone lay on the ground and rap the fuel tank at its lowest point (this is where the fuel pump is) at the same time crank it to start, if it starts decide where you want to take it to avoid a tow bill and dont shut it off till your there. otherwise if it does not start, when was the last fuel filter replaced!

Cranks but wont turn over


you know. i took it to a mechanic and actually.... The timing belt cut the Crank Shaft Censor... So it was the crank shaft censor again. The wires were routed wrong from the first mechanic that "fixed" the car.
