I have a 91 honda accord that is missing a bit

another suggestion is to run the fault codes and find exactly which sensors are faulty and then fix them

I hate to say it but you should of got the right part. That wiring is not to be spliced (for one, electronics)

sounds like the starter needs to be shimmed out just a little bit. either thast or you have teeth missing off of you flywheeel.

no, the plug is firing. But the timing is off. the plug is firing quite a bit before top dead center on that cylinder. The burning of the fuel mixture is occurring while that piston is on its way up and is slowing it down---dragging down the whole engine. i think you should change the distributor cap and rotor as cylinder one is firing at the same time as cylinder 2or 4. This indicates a possible carbon track in the distributor cap.

With the engine running are you getting any voltage off the alternator? check with a multimeter. Check voltage at battery while running should be 13 volts or more.

Check fluid levels and make sure they are topped off and not dirty.  Check ERG valve, check fuel filter, check air filter, check oxygen sensor, and check spark plug gap.  Also, hook this thing up to look for fault codes.

dizzy cap?? 91?? try changing the ignition module ,not sure where it is on this model it will be either under the coil or inside the distributor

do a compression test-hot and cold-check distributor cap for wear,cracks etc

If the timing belt is damaged(broken or missing teeth) you will get no spark. One easy way to tell is that many times the engine will sound different as it turns over, than it used to.

Ok start from the beginning, you are going to need a factory wiring diagram to make sure you are connecting the wires to the ignition coil where I believe you need to start
