Service start system light came on while driving.....was preceded by a popping noise.....the radio cut off as well....what is wrong....what is the fix?


did the engine stall, stall is 0 RPM.
at all stalls, The CEL glows, same as 1st key , CEL glows
this only means the ECU has power. nothing more,
CEL on running, means DTC ERRORS.
what engine is it? in usa, see under hood sticker (look up) and bingo
engine option.
2.4 L I4? ,has a cam chain ,not a belt.,,good. when working on any car with engine problems,first ID the engine

150K?

the car has a recall issue, see TSBs for alternator
the car has a bad tensioner.

and tests.
are you tooled up, and DIY ready.

Engine light flashing someone said reset the cel or disconnect the battery for five minutes


Lets start with what is cel? CEL stands for Check Engine Light.

It is true that you can disconnect battery for 5 minutes to shut light off but you still have a problem, When ever the engine light blinks it is telling you some thing is wrong and is causing cataylic converter damage, the only time the light will bling is when the engine is misfiring and dumping gas into converter.

You will need to have the problem fixed or damage will occur and light will come back on.
Go to an auto parts store, like an auto zone and have them scan the computer for the stored codes, if you can get me the codes i will help you solve the problem, i would bet the code or codes will be po 300 codes, but get the codes.
Also i will need to know what year,make and model car you have with the engine size, good day

My check engine light is on but my car seems to be running just fine. i checked my gas cap and it is on correctly.


For check engine lights (CELs) please head to your nearest AutoZone or Advanced Auto Parts. They will have a diagnostic tool that can read the CEL and pull the code. You can then look the code up and figure out what is causing the CEL. Once this is fixed the CEL should no longer come on.

Hope this helps.

Check engine light (CEL) problem


Yes the CEL should have turned on. Just turn the key to the run position and the light should turn on.If it doesn't, the bulb may be burned out. Also, if the coil failed and was driven for awhile, it may cause the cat converter to fail after awhile of driving. So, please keep that in mind.
