The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

SOURCE: Fuel injectors leak at fuel rail

Get some new O-rings, and this time put oil on them before you insert them into the fuel rail. The regulator is alright.The problem is that the o-rings can roll up, or twist when push em in dry. Had this problem once, easy fix, but was frustrating.

I have1988 Toyota pickup no fuel pressure. Checked

Friend, I know these Toyota Pickups inside out. Since you know the fuel pump is good, and has a clean fuel filter, then use a test light on the power side of the fuse and crank the engine over. If you don't have power to turn on the test light bulb, then the problem is in wiring between switch and fuse. Being EFI, the computer tells it when to power the pump. May not have power the first crank, cause is clearing, but ALWAYS power on second crank to start. The fuel still in the injector rail will be used first, no power on first crank, then once the pressure drops when that fuel is used, computer will make the pump come on.

Petrol pump

short answer, in the gastank.
we check fuel pressure at the fuel rail .
if good, the pump is good.
the FSM covers this in vivid details.
or at
The 2TR-FE is a 2.7L I4 gasoline engine. It features DOHC, 16 valves and VVT-i . Its power is 159 hp (119 kW) at 5,200 rpm, and 180 lbf·ft (244 N·m) of torque at 3,800 rpm with redline of 5500 rpm.
this engine?

this is used on our tundra. but that dont help ,as yours may have
different EFI , in your country.
you should get the FSM for your car and your country.
on the trundra we must pull the tank to get the pump out.
draining fuel and lots of labor for nothing...
why do that.
we just attach the fuel pressure gauge at the fuel rail
and check pressure,
in fact we do all 6 tests listed in the FSM.
:shut tests. presssure tests. , and regulator test , and leakdown test.
and injector balance tests.
most can not be done, right back aft as you are working the front.

40.8 to 41.7 psi) idle fuel pressure
5min. leak down test, 147 kPa (1.5 kgf/cm2, 21 psi) or more
data is for tundra of simular engines.
if the rail tap is missing, this works.

some factories save $5 by not having a test port.
this is the first part i buy for all my own cars.
for MPI engines. all.
many cars have a schrader valve present on the rail.
my jeep dont , i must used miller tool, 6539
do research online for your fuel rail needs and adapter.
i must have tool to do the injector balance test.
impossible to do unless you have 2 people. 1 under car
and one at rail.

Replacing a fuel injector on a 2002 volkswagen jetta

To replace the fuel injectors,first the fuel pressure needs to be relieved, then remove engine appearance cover.Then remove air cleaner and air cleaner ducting.Then comes vacuum hoses,remove the hoses and electrical connectors that prevent you from accessing the fuel rail. Disconnect the fuel send and return lines and unplug the electrical connectors for the fuel injectors. -------- You will need socket wrench to relieve fuel pressure and to remove bolts on fuel rail. Complete fuel rail assembly will come out with injectors,then you will have to remove injectors from fuel rail. -------- With new fuel injectors use new O-ring.Don't use old O-ring,use new O-ring. ---------- This will help.Thanks.Helpmech.

Im working on a 1986 toyota pickup 2.4l efi non turbo 4x4 i replaced the head gasket and i have a black wire coming from the intake wiring harness that has no plug on it .if i touch this wire to a hot wire...

Sounds like this wire should operate the electric fuel pump through the fuel pump relay.The fuel pump relay should start the fuel pump to maintain fuel supply to the common fuel rail and any surplus fuel will be bleed back to tank by pressure control.The injector opening sequence is contolled by computer once the engine is properly timed.
If you say the engine runs for a few seconds it would indicate fuel pump or relay is not getting power to operate or fuel pump is not delivering enough pressure to feed the injectors

I have a Toyota Sienna 2000. There is a fuel leak but Toyota can't find where it is coming from. Smell is emenating from the engine. Any suggestions please.

A good shop will add a fluorescent dye to the gas.. then use a ultra violet light to find the leak.

If your shop did not do this.. find one that will.

Also a good mechanic will check for other possibilities that may cause the car to run extra rich when it shouldn't. On this car that would be unlikely.. regardless..

If the car had a tune up recently.. someone may have mistaken the fuel injectors for spark plugs..and either did not reinstall the injector properly..or ruined/pinced one of the o rings or rail base seals in the process. Sounds silly..but it has happened..

Or perhaps one of the o rings or seals is failing.

Regardless.. have that dye test..and someone inspect the fuel rail and injectors for proper seal.
You are right to be concerned..leaks only get worse.. petrol.. not good.

Best of luck!

Fuel injector reeplacement

you don`t say what motor is in this so here is a basic procedure, find the fuel rail where the fuel lines connect to at the intake manifold.disconnect the fuel lines(be carefull you could get gas in your eyes from fuel spray or start a fire due to hot engine)these lines have high pressure fuel in them.look at the fuel rails to see what all is in the way to remove them and remove interferance items.remove the bolts that hold the rails to the intake manifold,gently lift wiggle the fuel rails and you may have to pry up on the rails in places to get them to come out with the injectors attached the should make sure any debris is removed from around the injectors so no dirt falls into the injector holes before you remove.then you can remove the injector to rail lock clips and remove the injectors from the rails.clean areas were the injectors will be going apply either gas or silicone on the injector O rings then install injectors to rail install lock clips and reassemble.replace all the O rings as they get dried out brittle and crack or removed components start car and check for fuel leaks.

Changing a fuel injector on a Toyota Carina 1996 1800, anyone have an idea how to change before I start?

Disconnect the wiring plugs from the injectors, Then remove the fuel rail (which is attached to injectors). Then remove injectors from the fuel rail. Don`t forget to change the "O-rings", (little rubber things on the end of each injectors). Otherwise there`s a possibility of fuel leak.
Also I suggest trying to clean the faulty injector at first, It might be ok, just dirty inside.
How to clean: Use injector cleaning fluid on the end of the head of the injector. Attach minus and plus to the contacts of the injector to battery of the car or any other energy source, and start pulling the negative wire on the battery on and off. You should hear clicking sound in the injector. Use the fluid and this "technique" for couple minutes or more, until the injector starts spitting the cleaning fluid evenly, not rarely. If still the injector doesn`t spit the fluid, you might need to change it.

Hope this helps, sorry for my english. I`m a lithuanian
