Bore Wash – Yes a Weird One
If your Nissan Pulsar Will Not Start then consider ‘Bore Wash’. This is when the injectors flood the piston bores with fuel and the pistons can’t get compression. This can occur when the car engine is cold and for instance, has been moved a short distance. Typically can occur to older cars when they first came out with fuel injection.
This is a weird one but read on as it fixes the problem.
If you moved your car a short distance, and the engine was cold, it creates a problem internally inside the engine.

So if you moved your car a short distance, say you moved it from the street into your garage and the engine was cold, what happens is the fuel injection system floods the piston bores with fuel and washes off the oil on the bores.
This is know as ‘bore wash’.
The engine cannot get compression. Continually cranking the engine makes the problem worse because the injection system keeps adding more fuel.
If it continually cranks with no firing response then this is what could have occurred.
Typically happens when the engine is cold.
How to Fix it
To fix it, you should take out the spark plugs and put a small amount of oil in each bore. Only a small amount of fresh engine oil. Approximately a tablespoon in each bore. Before you put the plugs back in – try and turn the engine over by hand or click the key to turn the engine over a bit so the oil is spread amongst the bore and doesn’t lock up.
Don’t put huge amounts of oil in. You only need a small amount.
Then put the plugs back in and it should start. It will smoke a lot as it burns off the oil.
This is a really weird problem, but if your car was fine before and operating normally and then all of a sudden just cranks and won’t start – then this could be it.

Other things to Check if That Doesn’t Work
You could have other problems, however these are all the things you could also check. It will help if you have a bit of mechanical knowledge.
Check the key chip is ok
Usually you need a key guy to check this. Likely if the immobilizer light flashes – then it would typically mean the key is ok. There is no battery in the key.
Check the battery terminals are clean and tight
Check the battery is healthy – although it probably won’t crank if it isn’t.
Do a scan
Do a scan by plugging in a scanner and check for codes. You need a scanner though and cheap ones typically don’t show all the codes.
Spray starter spray in the air-box
Spray starter spray in the air-box while cranking. This is if you think there is no fuel coming from the tank.
Make sure you have fuel
Make sure you have fuel in the tank. Did you put the wrong fuel in the car?
Replace both the cam sensor and the other sensor
Replace both the cam sensor and the other sensor at the bottom of the engine – apparently a common issue on this model.
Checked the immobilizer
Checked the immobilizer – red light on top of the drivers side dash board flashes when ignition key is off and turns off when ignition key is on. Should mean it is operational.
Check fuel pump is starting
Turn the ignition on and see if you can hear the fuel pump start. You should be able to hear a noise.
Check fuel is coming up to the fuel rail
Take the fuel hose off the injection fuel rail and crank the engine. Fuel should pour out fast. Be careful.
Check the main engine fuse
This is under the bonnet near the radiator at the front of the engine.
Check all other fuses
Check all fuses under the bonnet and under the steering wheel with a simple test light. You can put the test light on each of the small fuses – on the little steel bit and see if the fuses are blown. Some fuses may not come on when the ignition is on but you should be able to check most of them.
Put new spark plugs in the car
Replace the spark plugs.
