toyota accent 2003 with problems

[dirty hands]

i cant see toyota  corolla seca  accsent as a vehicle in this forum  or follow posts and  problems about  them in a search 

it has a starting problem  mechanics cant sort 

4 cyl engine  ..manual gearbox  properly serviced   new plugs leads .. no engine check light ..no fault codes 

great compression and spark/  new  fuel filter and pump fitted 

when cold  starts perfectly every time 

it is the  daily 

as the stop  park starts.. increase during the day ... it needs to crank more times  before  each start   

 

where to start looking  ?

check the fuel pressure on hot start. 

[dirty hands]

thank you for the suggestion 

tired of paying mechanics telling  me they cant find the reason 

its a very good reliable car 

so  trying anything DIY

will check that pressure 

 would  adding   off the shelf  injector cleaner into the tank  be a good idea 

[CHA54]

Off the shelf injector cleaner is nowhere as good as removing the injectors and having them cleaned properly.  Did the hot-start problem exist before changing the pump/filter assembly?

Cleaning the MAF is also a good move if it has never been done before, the intake air temp sender resides in the MAF assembly also.

the pump and filter were changed ....as mechanic said this was the starting problem

starting to cost way to much in fixing this ...by tossing new parts at it ... without result  

yet to get a CV  shaft  for it ..... the rest of the car is great 

i am trying to learn more about the car myself 

the rar /. ios repair manual for this car  is way too big ..5 hours to down load ....my end .

.and i cant find any  sections of it 

i prefer pdfs 

injectors were not discussed .... .i have found a mobile injector cleaning service that can clean them 

 Is there another  fuel filter somewhere

i thought  the  filter and pump under the rear  passenger seat  and is both filter and  pump unit is  combined

Yes, the pump and filter assemble into one unit in the tank accessed under the rear seat.  When a new filter assembly is installed, care must be taken to not pinch any of the O-rings on the fuel pressure regulator or pump outlet, if this happens you will have fuel pressure related issues.  Another thing to check is that the tank has it's breather clear.  When it's been sitting hot for a while before you try to start it, undo the fuel cap first and see if there's a large whoosh of air from the tank as you unscrew the cap.

Re-reading your original post, it states the plug leads were changed...  Do you mean the ignition coils?  as the 1zzfe doesn't run ignition leads.

I'd be grabbing a techstream cable or similar live monitoring tool and looking at the values the ECU is reading in real-time.

If it cold starts fine, it's unlikely to be dirty injectors causing the problem

no wooosh at all 

I will correct that ..plugs only were changed ..

coils must be ok

smooth idle 

after it starts  there is no missing or hesitation or under load problems

 

will post back any success in fixing this

update and solution 

will be fitting a new fuel pump as budget allows 

pumping pedal twice  worked. when hot . some times 

but inconclusive

Pumping the pedal has no impact on fuel pressure, have you checked the TPS signal when hot?
