I have a ford sierra carburateur engine from 1984 1600 l (cc)

Clogged fuel filter / clogged injectors / dirty air filter.
Fuel pump could be going bad.
Loose ground somewhere.
I have a 2000 GMC Sierra. I have replaced the ignition switch (its more of a harness than a switch).
If you have a check engine light on, this will help diagnose the problem. If you do not have one, then it is most likely a mechanical issue like a bad fuel pump or a loose ground someplace.
Things to note:
How long does it run before it shuts down? If its the same amount of time each episode, then it could be related to temperature.
Do you have any leaks? Check your fluids and make sure there are no leaks. These trucks have many safety features built into them that are dependent on fluid levels.
Any blown fuses?
When is the last time you changed the air filter, the fuel filter or the spark plugs?
Air filter should be changed / cleaned if you have a reusable one every other oil change.
Fuel filter should be changed every 30,000 miles (I may be wrong on the mileage, but if you do not remember when it was changed, I would change it. With the age of the vehicle this is more of a factor - even if the truck has low miles on it.)
Spark plugs are expensive but only need to be changed every 100,000 miles. Given the age of the vehicle, I would guess you are not the original owner and without knowing when they were last changed, it might be a good idea to "start over" with everything being new. These trucks will last forever if you take care of them. My Sierra has 217,000 miles on it and I just towed a full size truck 1500 miles with no issues. GOOD LUCK

check for codes this may help if their is one, some codes will set without turning on the check engines light.have the fuel pressure checked with a gage as a bad fuel pump will act this way. have the tps(throttle position sensor) checked for voltage dropouts as you move the throttle. the catalytic converter could be plugging up and need replacing. if you have an ignition problem usually a miss will be noticed. on other thing I can think of is possibly a transmission problem, I can only recall one that I`ve run across that this was the cause.

There are only a few things to check. I do not have a blueprint for this engine in front of me. There may be a pressure relief valve on the oil pump assembly and the spring is broken and allowing pressure to bypass.

Oil pump shaft- often there is a spring pin to secure the shaft to the gear driving it. If the pin is sheared the pump will not spin.

Clogged block, clogged cylinder heads, oil pump pickup fell off pump?
Too much play in bearings. Cracked block.

Was this an engine Salvaged from the Obama Gas guzzler Program? Those engines were treated with an oil additive to seize them up. Parts from these motors are junk. Don't use the used oil pumps.

Please rate my info.

Ticking sound could be coming from a Coil-on-Plug, or a pcv valve, or (hope it's not) a valve lifter which could be sticking. Sticking lifter noise often disappears when rpm's change, or the noise comes & goes. try changing the motor oil & filter right after adding an Engine-Flush Treatment to the motor oil, running the engine for 10 minutes at idle with treatment added to the oil, then draining the oil & changing filter while oil is still very hot. That last part is very important, so be careful not to burn your hands - be careful. -- The sticking lifter is a likely cause if motor oil has not been changed at frequent intervals in the past (every 3-4K miles) -- dirty oil causes sticking lifters.

Hello B Proctor,

Your catalytic converter has collapsed into itself... else check if you have a separate muffler there...

Check your on-line prices a rockauto...

Then take it to the muffler shop... or get that penetrating oil & get started...

take it to a shop sounds like you burned up the engine knocking is not good in an engine

This is quite tricky, the oil leak can be only due to a failure of the OIl seal or that the bearings after being worn out can damage the oil sealing.
So it is best that the unit be taken out in the engine side to be probed.
Now since the leak is more when the engine runs it is better to take down the unit for an overhaul , confirm and then replace the seal / bearings.

GM OIL LIFE SYSTEM - RESETTING
The engine oil life monitor will indicate when to change the engine oil - usually between 5 000 km (3,000 miles) and 16 000 km (10,000 miles) since the last oil change. Under severe conditions, the "CHANGE OIL SOON" light may be displayed before 5 000 km (3,000 miles). The vehicle must not be driven more than 16 000 km (10,000 miles) or 12 months without an oil change.

Reset the oil life monitor when the oil has been changed, use the following procedure:

1. Turn the ignition key to the RUN position.
2. Fully push and release the accelerator pedal 3 times within 5 seconds.
3. If the Change Oil Soon light flashes, the system is resetting.
4. Start the vehicle.
5. The oil life will change to 100%.
6. If the Change Oil Soon light comes back on, the system has not reset. Repeat the procedure.

Engines are like us humans. The better care they get the longer they last
\Change the oil at every 3000 to 4000 miles and do the preoper suggested maintenance by Fords outline in their manual for a long life
I own a 2000 Mountaineer with 190000 miles. It still runs like new although the body is starting to rot
The oil is changed every 4000 or sooner
Tuneups are done at 65000
Suspension is checked every year

the v10 ford has never been know any good fuel milage, if your getting around 7 mpg your doing good
