1991 honda accord wont start?

Ok i just recently found out when i did a tune up on my vehicle about spark plugs having a firing order. I had previously taken the vehicle to a mechanic due to the car having idling issues. The entire air intake system was replaced and cleaned very well before replacing. After bringing it back seemed the problem went away.

The car was sounding like a small misfire so i went ahead and replaced the spark plug wires as they were lookin old. I also did the spark plugs as well.

When i put the newer spark plug wires in the car sounded funny so i went ahead and turned it off. This morning i went outside and using a diagram put the spark plug wires in the proper firing order. The car cranks strong but it wont start.

What should i do at this point the car cranked up yesterday.

Also i noticed the check engine light flashes when trying to start the car up and i read that could be a misfiring issue. I am sure i have the wires in correctly and checked multiple times. Help please.
