My S500 is giving me some issues.

While I was on the freeway, my check engine light came on and engine was rough at idle(started smelling fuel). I pulled over and turned the car off for a couple minutes, but when i turned it back over to start it took 10+ seconds and me stomping on the gas to start back up. I eventually made my way back home (seen white cloud from exhaust and smelled fuel).

Checked the fault codes and it gave me p0304 p0130 & p0135. Went out and bought bank 1 sensor 1 o2 sensor and swapped it. When i went to start the car it still took a while to start but did crank up still rough at idle. Shut the car off and when i turned it back over it cranked for a second then i heard a loud noise then it cut off. Tried to crank again and it was sluggish, eventually not even cranking. Now i dont get any cranking when I turn key over. Look's like i'll have to take it to a shop and stop trying to save money.

Any takes on what's going on?

 

Could be a lot of different problems or just one that is causing it. HAve you replaced your crankshaft position sensor lately (CPS)? or you Mass Airflow Sensor (MAF)? Plugs/wires?

 

For some reason I doubt it that this will be resolved by just changing the plugs, wires. Especially after the loud noise!

Could it happen that the timing chain can break? If you are not sure what you are doing, bring it to a shop before you damage some major parts.

Sorry I couldn't help much, just had some ideas...

If its not cranking that's bad news. Is the starter engaging when you turn the key? If possible check if you can spin the engine with a 27mm socket or Allen socket(don't remember the size) with a breaker bar? Check oil?

 

It's probably not cranking because he wore down the battery too much

It still has enough juice to light all the lights but not to crank
