on a cold start, check to see if 2&3 are colder than 1&4. if so switch inner coils with outer coils and check for tempature again. you should clean the spark plugs while doing the switch. your pic shows 2&3 are not firing, the resistance should be all the same for all coils about 8-12 ohms, if so , check the pick up coil resistance, they should be the same for 1&4 as 2&3. hope you have a meter?
