I have a 98 accord v6 and it cranks but doesn't start... its been doing this a couple of times and after leaving the car sit for about 30 min and then try it again it would start. One day I went to start the car up (the car was cold) and it started right up, so I drove not even a half a mile to the gas station and after filling up, I tried to start the car but it would just turn over... so I let it sit for about 30 min and tried it again and what do you know it started... well today I wanted to start it but it would only turn over, I let it sit for 30 min but nothing... im clueless please help

Replace the Ignition Control Module (ICM) and coil:
