1990 300E crank no start
 

The car was sitting for 3 weeks and upon start up it cranked but no start. I checked the cap, etc and everything seemed fine. Start to drive and it has a low speed miss that goes away and then on hot restart starts but half hour later won't.

I hear the fuel pump energize. what are the symptoms of crank angle sensor or coil pack? I hate to throw parts at it needlessly. Again cranks well and battery OK.

Cheers
