Engine just shut itself off while driving and starts a a few minutes after


The engine temperature is normal?
If any warning lights have appeared on your dashboard, this may point towards a faulty sensor such as throttle position sensor, Oxygen sensor ..

If you have no warning lights it sounds like a classic case of a faulty/failing fuel pump.


Nissan Sentra Fuel Pumps

A quick check you can do is to disconnect the fuel line somewhere in the engine bay and turn the ignition on. Fuel should literally spray out.

Before buying and fitting a new fuel pump get somebody - a workshop - to do a pressure check on it/ confirm that it is the fuel pump.

A faulty/failing fuel pump can work intermittently. One minute it's fine, the next minute it stops working.

How can I check the fuel presure in Toyota tacoma engine 2.4


Sorry am not sure whether Tacoma engine is petrol or diesel, what age it is or what fuelling system but assuming it is a conventional petrol injection system, the fuel pressure test is just one of four tests carried out when a problem with fuel delivery is suspected and begins with fitting the appropriate adaptors to the fuel line and then fitting a pressure gauge.

It is not just the correct fuel pressure(s) needed for satisfactory engine performance but also sufficient fuel volume.

Before carrying out the tests is is usually necessary to fit a switch in place of the fuel pump relay so the pump can be started with an open line and the engine switched off. The amount of fuel delivered into an appropriate container in a set time is measured and compared with specs.

The next test is the peak pressure test - a momentary test with a closed fuel line to test the mechanical strength of the pump and lines.

The next test is the regulated pressure test with the fuel line again connected to the engine and the enriched pressure recorded and compared with specs and finally the engine is started or vacuum applied to the regulator valve with a hand pump and the lean or normal pressure is recorded.

With some older engines it is possible to easily install a pressure gauge with universal adaptors but as later engines tend to use quick release fittings an number of special adaptors will be needed.

gas or diesel ? if its gas find shrader valve (tire valve looking thing) on injector fuel manafold top of engine tap key on/off several times depress center of valve with plastic point nothing metal (old ink pen?) look for fuel to briefly spray out a bit (shield eye's) no fuel ck fuel pump , filter and inertia switch ,yes fuel ck all the sensors the injectors are not firing
Diesel ? A 86 would be A IdI type so loosen fuel fitting(one turn) to top of # 4 injector (you can't reach others) Do not remove it (High pressure!!!) crank engine several times over look for fuel leak at fitting thats loose ,it might even start if injector pump was airlocked that happens alot from sitting ,if it does don't get your body near loose fitting(high pressure) too dangerous shut off key and tighten fitting then restart engine

My hilux wont start i replaced a seal on the pump now wont start got fuel to the pump dose not seam to be getting to the injectors


if this is a diesel L or L2 engine chances are you've got trapped air in the steel lines from the injection pump to the injectors loosen- but do not remove- the fitting holding the fuel lines to the injector start/crank the engine until fuel spurts out the loose fittings. tighten fittings. start the engine. this will have the engine running if the problem is trapped air.

I need to know witch of the three line's go to the fuel pump 1-fuel to engine 2- return 3- vent


They are usually different size fittings and can't be hooked up wrong, the easy way to know is look at the pump, the kinky line that goes into the top of the pump, is pressure. Usually the pressure barb and fitting is the largest, the middle one is evap, and the smaller is return.

Bleeding air out of fuel inj pump


loosen the fuel fitting on the fuel filter housing.
loosen the actuating button on manual pump. operate pump until fuel flows from the filter fitting free of air.
tighten fitting
continue operating the pump untill injection pump overflow valve opens up. This is known by an audible buzzing noize when the valve opens up.
tighten the pump acuator button.
Start and run the engine. check for leaks.
Hope this the info you are looking for
