My car is 2001 Camry , 4 cylinder 2.2 engine , it's about 122.560 km .
It is hard to start when the engine is hot . It usually take 2 cycles ( or turns ) to start the engine when it 's cold .
If it is hot , it takes longer to start the engine , the engine will turn 6 or 7 turns to start .
I tried to replace : spark plugs ,air filter , fuel filter , coolant temperature sensor , timing belt . I had injectors cleaned by dealer . But it didn't work .
Please help me . Thanks .

 

Might be the Idle Air Control valve (IAC) or fuel pressure regulator.

 

Please tell me where the Idle Air Control valve (IAC) and fuel pressure regulator are . Thanks .

 

IAC valve is under the throttle body. Suggest a Google search on cleaning the "IAC valve 5S-FE" which should result in many hits. A solvent cleaner is sprayed into the IAC air intake port. Use a throttle body cleaner that is plastic safe (do not use brake cleaner).

The fuel pressure regulator is at the end of the fuel rail having the injectors (passengers side). If the engine has one it will look like a small can (Toyota want on to move the requlator to the gas tank under the fuel pump).

The website www.autozone.com should have info on the above items in their Vehicle Repair Guide Section.

 

thanks Toyomoho . Merry Christmas and happy new year .

 

Hello Toyomoho ,
Would you please tell me to remove rear seat of 2001 Camry . I want reach to fuel pump . I don't see any bolt of the seat . Thanks .

 

Merry X-mas to you and your family.

The lower seat pulls up from the front. It has a couple of tabs that drop into slots in the chassis.

Pull up on each side on each side of the seat by gripping under the front edge. Once released pull the seat out forward.

 

Hello, thank you very much for telling me to remove the rear seat. I see the cover of the fuel pump but no screw or bolt, look like it's glued to the chassis. Do i just pry it off and glue back after finish the job?

 

Typically there are a couple of sheet metal screws holding the cover down. The cover is a thin steel plate covering a hole in the chassis, below which is the actual fuel tank.

Once the cover is removed you will have access to the top of the fuel tank and the fuel pump access cover.
