Just because you hear the fuel pump running does not mean it is pumping. You could also have a clogged fuel filter. Have the fuel pressure checked. In some cars like a '90 Lemans the fuel pump is connected to another metal tube on the fuel pump mount, by a small rubber tube about 1" long. Over time the rubber breaks down. The fuel pump will work, but little or no fuel will go to the engine. Pull pump assembly and replace the tube for a couple of pennies.
The shaking wheel part suggest that there might be an engine misfire, the engine light on suggests that the computer is trying to tell you what's wrong. Connect the engine to a diagnostic computer to see what's going on. The computer can often give you hints to the real problem.
That means that the computer see's a problem with the emmission system are the transmission. Need to have engine scaned with a engine scanner to see what is going on.
There is a problem with the emissions system. Need to have engine scaned with a engine scanner, and it will tell you were the problem is and whats going on.
You turn off the check engine light on any vehicle by finding out why it is on and fixing the problem. That light is on because one of the electrical leads going to the engine's computer is saying, "We have a problem." You can hook up the car to a computer and find out what the problem is. You can attach a light down below the dash and count the number of times it blinks and check a chart to get the number and then compare the number to a chart and find the problem. Or, you can cut the wire behind the dash.
Try going up one grade in fuel octane
it controls sensors that tell engine how much fuel air and electrical to make engine run smooth , by telling computer whats going on . computer adjusts all three
NO. A knocking noise in the engine is a problem in the engine.
If the check engine light has come on and stays on it can be a minor or major problem. The light is on because the computer has detected a problem with the emissions system. Something is not right although the car may appear to be running fine. You mileage may be adversaly effected, and you may end up destroying the catalatic converter. My advise would be to have it checked to see exactly what the poblem is. Ignoring the light may prove to be a bad decision.
When the key is on but engine not running the lights on the dash come on as a self test. With the engine running the light going off is a good thing, it means no problems detected by the onboard computer. The light would only be lit when the engine isexperiencing a problem, need tohave a scanner hooked up to read the codes to see what is going wrong.
Yes, if a sufficient quantity of gasoline went through it. Knock in the engine from detonation is going to be the main problem, which could ultimately render the engine useless.
What can the problem be if there is no cam single leaveing the computer.there is one going to it
Possibly a wheel sensor, VSS or other problem. Check the computer diagnostic code to find out what's going on.
