    Once I had the check engine light come on and it was bad gas. As soon as that tank was gone and i refilled, it went off. About a year later it came back on and has been on for over 2 years. The guy who changes my oil checked the code and it is actually the sensor that lights the check engine light. sheesh,

    My light came on once on a long trip. It was bad gas. Once that was all run through and I filled up again, it went off. About a year ago it came on again and stayed on. The Valvoline guy ran the code and it is actually the sensor that tells the light to come on that has gone bad

    ...go figure.

Turn the key from the run to on position three or four times and the odometer will display the error code.

You can take it by autozone if one is near they will tell you the code. check your gas cap if it was loose this will cut light on.if that is problem light will go off after a few good drive cycles. or get code and let me know what it is and we will go from there

U will have to have a test run on the power train module (PCM), any parts store like Kragen auto etc. will do this for free, when you get the trouble code for the light post it on this thread and I will tell you what the problem might be.

What does it mean when the check engine soon warning light comes one?

If you read your owners manual you will learn something,
not much, but have to start somewhere

Check lights have been on all vehicles since 1983, some
31 years. SO--I don't know what to tell you, when you say
you don't know what it means

You can speculate all you want,what you need to do is check for
codes,again what most people have done for 3 decades,look
them up & then have a repair shop diagnose the code fault

You provided no vehicle year,engine,OBD2 Codes

Have no vehicle history on maintenance,or if someone
just put the problem in there

Intermittent starting problem

I don't know why you even ask a question, until
you get the codes & diagnose the check light issues

Surely you have a check light on all your vehicles
once a year, as most people do.

Any time you get a check light, things stop

You stop using the vehicle & at least get
the codes & diagnose the problem
Then you can decide if it is safe or wise to use
until repaired

If not for the check lights,I would say you don't
have fuel pressure when you turn the key on
Check that with a gauge on the engine

I don't know which it is

Your info is limited but when you say the "alternator" tries to turn I can only assume the engine is cranking. If it is and not starting check the security light on the instrument cluster.. If its blinking put the key to acc and leave it for 10 min or until the light stops blinking. Turn the key off then start it. This is a common passlock issue.

The truck wont start and when i open the door the alarm light is blinking and check engine light is on and comes on and off every 7 to ten seconds

You have to turn the alarm system off. It is keeping the car from being started. I hope you know how because I sure don't. These alarm systems cause more problems for owners than for thieves.

Car wont start

You need to know if the fuel pump is working.TURN KEY ON,BUT DON,T CRANK engine, Listen for the pump to kick on(should hear it.)IF the check engine light is on,have it scanned. A bad crank or cam sensor could prevent starting.IT could be anything from bad plugs,wires,out of gas, or bad sensors.
