Hyundai Repair: Random Quitting, fuel delivery system, fuel management system

Question
QUESTION: I have a 2000 Hyundai Accent (1.5L, 12V).  The car sat in a parking lot for 2 years prior to me purchasing without moving.  I have replaced the fuel pump, fuel and the fuel filter (along with the alternator, oil, plugs and much more).  The car started and ran good at first, then quit.  We did some work to the rear suspension and the exhaust just prior to the car quitting.  We had been driving the car and just put the car in Park at the time it quit.  Why won't it restart?
ANSWER: Hi, Eric.  First, I'll need to know what sort of behavior the car is exhibiting.  Once I know that, I can advise you on what to check to narrow the possible causes.  Right now, it could be related to your electrical system, fuel management system, fuel delivery system, or engine mechanical system.

Does the engine crank when you attempt to start the car?  If so, does it crank slowly, quickly, or at the normal cranking speed?  If not, do you hear any noise when you attempt to start the car?  Where does the noise (if any) originate?  Do the headlamps operate when the key is in the "on" position?

QUESTION: Headlights only operate manually.  The engine is cranking at normal speed.  While cranking, there is a smell of gas from the plug hole, but there is no spark from the plugs.  The car will reset after a lengthly period of time and restart, but only run for about 2-3 minutes before turning off.  There is a light squeal when the engine first starts, but it stops squealing almost immediately.  Sorta sounds like a piston is dragging.  I also checked the fuel pump relay and it seems to be working. -- Thanks.

Answer
Okay.  What you've told me implies that the battery and charging system are probably okay.

Let's start with the lack of spark.  How did you determine that you have no spark?  If you indeed have none, you should check to see whether the check engine lamp illuminates (for at least a few seconds) when you turn the ignition key to the "on" position (bulb check).  If it doesn't, you should suspect a problem with the ECM or it's power or ground.  If it does illuminate, you should suspect some sort of problem with the crank sensor.
