Starting Problem - 2001 Lexus IS300

I am having problems infrequently starting the car. I get into the car perhaps once a month, and the car won't start. After a few hours or days, it then starts. I have taken the car to Lexus, but they don't know what the problem is.

    I had this same problem but it was caused by a loose battery cable. Thankfully it wasn't anything big.

    I use to have this problem about 2-3 times a year, it didn't bother me to much. However my rad got a leek which resulted in GBP2000 repair bill due to my engine overheating. The radiatior and ing coils where replaced and my head gasket skimed. Paid Lexus to do the work so a "proper job" was done. Now this start problem happens when I start every morning or if I leave it for 12+ hours.

    The "trick" I use most days is to floor the gas pedal then turn the key and let go of the key after 1 second, car starts 9/10 times (don't let the rpm go over 2k-3k). Please note if I stop the engine straight away and restart I don't have any problem.

SOURCE: how do i get my lexus is300 cds out?

the only way to get them out is to remove the unit from the car and disassemble it. if you replace the unit it will go to an exchange company and if you request it they will send your cd's back.

Sounds like a problem I had with my 2000 ES300. Cleaning out the IACV (idle air control valves?) took care of it, at least so far.

Cranks but won't run.

I firmly believe that Lexus should be serviced by the dealership. Mine is done every 8 months. They have the diagnostic equipment and expertise. First thought on yours is fuel pressure, or a faulty sensor. Put it on an OBD11 Code Reader. The test connector for fuel pressure is on the fuel rail near the bulkhead.

Others have the same fault!

Have a 2001 lexus is300 with a code p1125 won't start what's wrong

The code is for a failed throttle control motor or circuit.
You might check to see if the throttle control is plugged in, otherwise you may need a shop manual to test the component.
