HYUNDAI ELANTRA SPARK PROBLEM

2000 Hyundai Elantra • 167,000 miles

Car was running rough. Had miss in cyl#3. Changed coil pack and plugs. Same thing. Hooked up spark gap tester on 30. No spark on 3 and random spark on 1. 2 and 4 are strong. Changed 2 and 3 wires same thing. Antthing else to check besides the computer.

Try taking your ohm meter and test the plug in to your coil pack you should have a 5 volt reference and a ground

If you have sparks on 2, there shuld be sparks on # 3 as they use the same coil and fires simultaneously. Did you replace the plug wire?
