engine problems?

[need4speed125]

So, I went to go start my car this morning, and when I put the key into the ignition the engine sounds vey unhealthy.
It makes a rumbling sound. Does anyone know what could be causing this and why?
And approximately how much would it cost?
Thanks.

Need more information - exactly what do you mean by "unhealthy"?

What is the model year and mileage of the car?
What was the maintenance history of the car?
Was the car hard to start, slow to turn over, etc.?
Give a more detailed description of the rumbling noise?
Fluids all topped off and in good condition?

Could be anything number of things - from a loose heatshield, to bad gas, to generally cold weather, poor maintenance - excessively viscous motor oil, worn plugs, ignition issue, weak battery, etc.

You can't tell how much it costs without doing some diagnostic work first - or you could just take it into a garage and pay about $85 for them to do the diagnostic for you.

If you stayed on top of the maintenance, all fluids checked out, and the car hasn't done it since then - probably nothing wrong with the engine at all.

its an 01 corolla w/ 99k miles.
as far as i know its been maintained good, because my uncle gave it to me a year ago.
the battery died a lot in the first few months, however i used jumper cables.
To my knowledge his wife maintained pretty good, took it to Toyota.
But whenever, i turn it on the engine rattles. i need to get new brakes, b/c they squeak, need an oil change. recently changed the timing chain about a year ago.
