Well, if it's directly hot wired, then you can narrow it down between 2 broad things.

Not delivering power to the motor:
- blown fuse?
- failed relay?
- cut wire somewhere?

Bad motor:
- run a pair of wires directly from the battery to the motor. Does it run?

After you decide between those, you can decide whether to restore it to factory configuration or fix it back to the previous owner's hotwired configuration.

Guessing failed relay, because I turned the AC on and the AC fan doesn't turn on

And yet another question does anyone have a diagram that shows what fuses go where and what they are for, for both the fuse box under the dash and the under the hood fuse box my car has neither diagram and the under the hood fuse box is missing two fuses that go directly behind the fan relay I'm trying to find out what they are

Here is the online manuals link in the diy section.

https://www.hondaaccordforum.com/for...-manuals-4597/

open the hondatech link and get a pdf of the 94 accord shop manual.

I would start by testing for power on the wire that should connect to the fan that was cut by the previous owner. You may also want to test the pins that power/ground the radiator fan relay. Two pins will have 12V to ground with the key in the II position. One pin will switch on/off to ground. The 4th pin would power the fan motor and that is likely the wire that was cut.

And yet another question guys? Sorry to bug ya, does a map sensor have anything to do with this accords engine running "rich"?? the plugs are brand new, the wires and distributor..we pulled them again and my dad says it's burning too much fuel and I can notice it in my gas hand

Fuel rate is driven by MAP & RPM so a bad MAP sensor can do that.

An MAP sensor reading high will put in more fuel. The O2 sensor can see that as a lack of oxygen in the exhaust, but it can only compensate up to it's limited authority to adjust fuel. But then I suppose it should throw a check-engine light if it's still rich??

Problem with this nightmare of a car Jim is that the check engine doesn't work, simply put I bought a lemon

Where is the radiator control module locate on my accord? And how hard is it to take out and replace?
