I have a Hyundai Sonata 2002 automatic which has just broken down. What happened is that while driving the engine suddenly stopped and the check engine light turned on. I attempted to start the engine but soon after it started it died again. The next time I start it, the engine just cranks but won't start at all. The next day I attempted to start and again the engine started the first time but failed soon afterward. After that it does not start at all. Would appreciate if someone can point me on what might be wrong? I know that an exact diagnosis cant be given but just curious to find out any possible things to look for and estimated costs.
Update some more info I heard from another mechanic: There is no spark and no injector pulse. He believes it could be that the immobiliser is killing the spark. Not sure what that means and would appreciate if someone can give more info on what to expect and estimated costs if the above is true. Another interesting thing is that, occasionally, the engine starts but dies after a few seconds and then won't start at all for long time.
I have also found some info here but cant seem to make much out of the discussion over there. The only thing that I got is that I am having exactly the same issue. This also looks similar to my problem.
Also, this mechanic just wont give me a fault code and one of the other mechanics told me that his computer is incompatible with my car. Moreover he has pointed me to this site and told me to contact them and see if they can help me. I have no clue what to do now and I am not sure why he wants me to contact the company in the link. I will have to wait until Monday to speak to them.
I know I can't fix or diagnose it myself and I think what I am looking for is some advice on what to expect from mechanic, estimated costs and how to deal with him so that I just don't get totally ripped of.
