QuestionIm sorry, the car is a 1997 Hyundai Tiburon the car currently has 240,000 km. Its far the best and most reliable car I've ever owned an I will not be parting with it anytime soon. I installed a Cold air intake in my tib, and since then the Check engine light has shown up. I tried resetting the computer by unhooking the battery ground and pressing the brake light till it drains the power from the system and it stil comes on ...any suggestions?

-----Question-----
Hi,
I had some problems with getting no spark from the ignition coil and ignition issues. I read some of the questions about ignition from other posts in this thread. Where exactly is the crank sensor? Can I replace it myself? How can I check if I am getting power from the alternator to start the car? I just replaced the ignition coil and have brand new plugs, i also checked all the wires to see if there is any fraying or shorts. Everything seems good. Is there anything else I can check. BTW the car turns over, but no ignition.

It's always a good idea to check whether the check engine lamp illuminates for a few seconds when the ignition key is turned to the on position when there's a no spark condition. A no spark condition typically indicates the computer isn't trying to run the engine. If the check engine lamp doesn't illuminate when the key is in the "on" position, that's an indicator the the computer isn't powering up properly.
You don't need any power from the alternator to start your car. In fact, if the battery were capable of maintaining its own charge, you wouldn't need an alternator at all. If the alternator stops producing voltage, the car will continue to run until the battery becomes discharged to the point where it can no longer continue to start and run the car.
Most crank sensors can be changed by the majority of do-it-yourselfers. Unfortunately, since you haven't told me the year and model (and engine) of your car, I cannot tell you where the sensor is or give advice on how to change it. Please follow-up with that information; I'll be happy to give you further advice.
AnswerThe crankshaft sensor is located on the front of the engine, on the end nearest the transmission. It'll be partially obscured by the exhaust manifold. It attaches to the block with one 10mm bolt.
If your check engine lamp is back on, have the trouble codes read. Since it's returned like you say, there's an actual problem present. The trouble code will help you know what to check first. Once you disconnect the battery, you will have cleared the trouble code and won't be able to get any diagnostic information from the engine computer until the car is restarted and the code stores again.
