Code 93

September 18, 2008

I've had this Avensis Tourer from new ( Oct 04 ) and until February this year all has been OK. One cold morning in February it stopped after a few minutes and proved difficult to restart. Long and short was RAC came along, car started and Code 93 was logged. Happened again and took car to Toyota garage who diagnosed faulty pump and injector quoting £ 2,500 for repair. Declined to accept this and took it to an independent specialist who found a blocked fuel filter ( 60,000 miles of genuine Toyota servicing and it looked original ) and suspected some dirty fuel. Small bill included cleaner abd car ran faine but overfuels in traffic on occasion so emits some horrendous clouds of blue/black smoke.

Then I had the infamous strter motor fault which confused issues but a new starter fixed the hot starting problem in August ( 75,000 miles ) but we still have the cold start problem. Car starts, runs for 2 minutes, we hear a click from under the bonnet and the engine dies from lack of fuel. Engine management light stays on and code 93. The Toyota garage won't tell me and when I rang Customer Services in Reigate their response was and I quote " Our technical department is not customer facing" or in other words we won't tell you either. Fed up with this so threw some more cleaner in the tank which helps and swapped the grey relays around ( long black box behind left hand wing by the Battery ) and for last two mornings no start/stop or code 93. Just need to sort out my smoking habit in traffic.

So has anybody else had similar problems and got any adeas for a cure ? By the way my pump is giving over 300 bar and I am still not convinced it needs to be changed.

hello

before final solution -- try to check with reliable garage -- what delivery pressure must be after HP fuel injection pump.

300 bars looks like a small P for modern rail system. but i am not sure. try to verify.

Both independent spcialist and RAC say that that is OK bit Toyota give 350 bar on the latest spec Avensis though I am not sure if this applies to the older spec cars.

hello Adrian

now the main task is to disclose the pre-adjusting opening pressure for all four injectors as per manual (!).

in case yr HP pump criates P more than 300 bars then it might be sufficient .

anothey way - do you know when all the injectors have been last serviced? You state 60k miles.

normally the diesel injection system is reliable in case you change the fine fuel filter regulary.

i feel you have a minor problem that criates a head ache etc. have all injectors tested first and pay max attention of the spray jet that must be normally sharp having no diesel drops on the nozzle tip edge. i do not go further now (there are many other problems resulting poor startiing).

as to the HP pump -- it has only one plunger with barrel with very precised gap, as well as delivery valve. in case the pump does not criate the pressure then the more like reason is delivery valve/or spring) - it is clear can be checked in case you mount pressure gauge into the rail instead of injection pipe.

start from injectors and revert.
