Alright, so my 1994 Honda accord cranks but there is not start. I checked the plugs for spark, they have it. I checked the fuel and it is getting to the plugs. I replaced the distributor cap and rotor also. There is no air box on the car and the intake manifold is not sucking air in. Is this the problem?

 

Well, check that the timing belt didn't snap and also check that the single wire on the S teriminal located on the starter solenoid didn't come off of there. Mine did that a few time and get a Ebay 3" intake for that then if it didn't come with an air box.
