It could be due to lack of fuel being supplied to the engine. And you do not have power because there is less fuel being sent to the engine. It seems the fuel pump is malfunctioning. Please have it checked and repaired.

Hi! Theres a lot of things to look at. Be sure that the timing belt/chain is not broken for this will bring severe damage to the engine if forced to start. One good thing to get this right is to have a reputable mechanic to check on the engine. Hope this helps and thank you for using FixYa!

    So it still runs, just a knocking sound? You may want to check on the PCM (powertrain control module). The computer may be faulty thats why it doesn't respond.

What would cause my car 2 die immediately after i start it


I had a similar problem with a 2000 Sunfire. The temp guage was not reading and the t/c light was on. There were no codes displayed. After some research I checked the resistance of the coolant temperature sensor and it was much to high. 100,000 ohms and should have been 2000-3000 ohms when cold. A new sensor solved the problem. There are other things which could cause your problem but this solution worked for me. Replacing the sensor is easy depending on it's location in your car. You might have to drain some coolant. Be careful and take precautions. Do it when the engine is cold.

My 200 pontiac sunfire died and lost power on the freeway yesterday and refuses to start again makes a click sound and nothing


Possibly a loose or corroded connection somewhere, or bad alternator, not charging battery and caused system failure. Check for good clean connections at battery and starter. With a volt meter a battery should read 12.4 - 12.6 at rest, if you have a functioning alternator battery should read up to 13.5 to 14.5V .

Oil light comes on when warmed up and makes slight knocking noise on a 2000 sunfire. what is the cause?


It's most likely low oil pressure. This should be checked out by using a mechanical guage, assuming you have checked the oil level and it is full. This is likely a result of high mileage and old age so unless the engine is in pristeen shape, your best bet is to probably start using a higher viscosity oil, like 15W40 or 20W50. Putting a new oil pump in an old motor isn't normally cost efficient. You put the pump in and then you start fixing other things. The heavier will build your pressure and make the knocking noise go away for a while. It's time to consider your options. Hope this helps.

My 2002 Impala started knocking while on the freeway. I couldn't try past twenty miles per hour without it knocking again, I put two and a half quarts of gas and it's still knocking!


ok just checking well usaully when it starts knocking that means that either the cam bearings or the crank shaft bearings are already damaged and if the knock is coming from either placemits not good how many miles are on it

I steam clean my motor today then change the oil,spark plugs& flushed the cooling system,the car ran great for the first 20 miles then it lost power and the engine died it took a while to get it...


YES,you steam cleaned the engine,it may right itself after drying out(hopefully)when you steam clean, the water particles are much smaller than a normal "hose down"so you may have wet the electronics.if it starts, then let it run for awhile to (hopefully)dry out itself.
