There is a relay mounted way up under the dash on the driver side. It is about 1"x1"x2" and it says Mitsuba on it. This is the PGMFI relay, sometimes called the main relay or fuel injection relay. It is very likely the problem. You can buy another one, or there was a bulletin on how to repair it. You need to take it out, pop the cover off, and resolder the cracked solder joints on the pc board that the relays are mounted on. Really not that hard if you have a little soldering experience. If not, just buy another one, about 50 bucks.

You need 3 things.
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 13-13.5 lbs on your TBI
If you have all 3 then move on to injector pulse to both injectors.
Keep me posted and recheck your spark plug wire to make sure they are not crossed. firing order 1-2-3-4-5-6 cylinder # passenger side 1-3-5 front to back. cylinder # drivers side 2-4-6 front to back
distributor #1 is located at the 7 o"clock and rotates clock wise so next distributor post on the right working clock wise is #2. Good luck and hope this helps.

A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.
