Dear Malcolm Brindle,

Try making sure that you have your carburettor or fuel injection correctly set. Then check your engine timing. Also check that none of the major engine components are faulty. Dont rule out the possibility of a fuel leak somewhere in the system; so be sure to check everything thoroughly.

If this still does not solve the matter, get in touch with me and I will investigate the matter for you more in depth.
In the meantime I hope this is the fixya for you, and I do look forward to hearing how you get on.

Yours sincerely

SOURCE: check engine light is on, mpg seems to have

Stop at one of the big autoparts stores and they will scan it for free, and that should point you in right direction of what is needed to repair it. If not, get back to us with those codes and we will gladly assist you further. It's faster and cheaper to do it that way, than to guess at it.

SOURCE: i have a petrol 2.6

Engine Coolant Temperature (ECT) Sensor OPERATION The Engine Coolant Temperature (ECT) sensor is mounted in the intake manifold and sends engine temperature information to the ECM. The ECM supplies 5 volts to the coolant temperature sensor circuit. The sensor is a thermistor which changes internal resistance as temperature changes. When the sensor is cold (internal resistance high), the ECM monitors a high signal voltage which it interprets as a cold engine. As the sensor warms (internal resistance low), the ECM monitors a low signal voltage which it interprets as warm engine.

Why is my fuel gauge stuck on full even though there is only 50% of petrol in the petrol tank

I have a 2008 Chevy Colorado and today my temp

when a temp gauge drops to cold ,it indicates a problem in the cooling system
temp gauge sender units need water to activate the resistance that makes the gauge read so a falling gauge indicates no water around the sender unit --- air lock in the system--faulty wire connection to the gauge sender unit
the ac unit is not connected to the temp gauge so there may be another separate problem there
the temp sensor is an entirely different unit to the temp gauge sender unit and the short term working would be from an altered coolant level from changing that sensor --air lock in system
the temp sensor connects to the ECM to activate the fans and monitor engine operating temp so as to keep the air/fuel mixture exact for the engine conditions
the temp sender unit just makes the temp gauge read
a faulty thermostat will either be stuck open and the engine temp will take a long time to rise or it will be stuck closed and that will cause an overheat very quickly

When jackaroo 1988 is motoring where does the needle in the temperature gauge normally be

If your temp gauge has only the cold (C) or hot (H) letters then the operating range would be the width of the needle under 1/2 way between c and h. If it remains steady at slightly over 1/2 way that would be just the setting of the gauge. How to get to know where the needle would sit at a specific position in relation to water temp. Do the following
Remove the temp sender unit and attach an earth wire to the body of the unit to earth. Place the sender unit in a container of water up to the threads .Put a mercury thermometer in the container beside the sender unit Apply heat to the container and watch the gauge needle move in relation to the thermometer reading. Operating temp will be about 80 degrees C on the thermometer and that would be about 1/2 way on the gauge.

My c 240 v6 petrol 2001 displays a low priority warning light on the dash,advising that the oil level cannot be checked i have been advised that the sender unit needs replacing , does the sump need...

Sender can only be replaced. If you actually have a problem relating to oil you will see the temperature gauge rise well into the danger zone. As long as operating temp is normal you can relax when driving and get sender changed at your leisure.

Jeep Cherokee went from 18 MPG tp less Than 8 MPG over night.

There are several items you can check there. Your temperature sender if bad can make the computer think the engine has not reached normal temp, causing the computer to add extra fuel, Your MAP sensor can do much the same thing as can the Throttle position sensor. I'd also check the fuel pressure regulator as default is to a higher pressure than normal.
Manifold air temp and O2 sensors can do that too, but normally not that drastic of a difference.
Testing can be done using a digital multi meter and a haynes or chilton manual as a guide. Begin by having a code scan done (most larger parts stores do that free). Also, make sure the fuel system and lines aren't leaking anywhere...that can use up lots of fuel as well.

Temperature Guage, '89 Camry

the cable going from the gauge to the sender unit is an earth return. if you take it off the sender unit wire if the gauge does read hot the sender and earth it out the gauge should go to the hot segment.dont leave this cable to earth very long do it quickly. if the gauge does read it is ok, there is no earth to the petrol tank. if it does not read it will be faulty. hope this helps.

Gas milage seems to have dropped.

26 from 28 can be as simple as low air pressure in the tires and outside air temp changes.
