alright so ill start at the beggining. my timing belt broke a while back. it was a big deal cuz the car has been in the family and all. so i decided instead of selling it or paying someone else to swap the motor, me and a couple of buddies would do it. so everything came out fine and everything was dandy. then i go to check on the motor that i was buying, for three hundred bucks, and the guy told me it had the carbuerated engine from japan. i was like its chill, ill just use the old intake manifold. so i got the motor in and put everything on, and after a bit of fiddling, it started up no problem. but the wiring harness is a bitch and im not sure where everything went. so im not getting an engine temperature reading, and the car is idling really really funny, and after about ten minutes my buddy noticed my cat was glowing red. quick shutoff. i saw my idle air control valve and it was all fucked up, so i go to the junkyard and pick another one up, and put it on it didnt fix anything. so then naturally i tried it again. the starter got weaker and weaker the more i tried it. so i trickle charged the battery over night and tried it again the next day, and it wouldnt start. that said to me that the alternator was bad, (i had one bad alternator of the three i had in my backyard and i wasnt sure which one was bad). and when i put the other one on it gave me the same problem, so i thought, hey the battery is dead. so again, i charged the battery and tried to start the car again. this time it didnt even spark and the main relay in the car makes this annoying buzzing sound. so i was like...hrm thats the problem the main relay got friend from the trrickle charging. yeah im stupid, leave me alone.so i got another relay from the junkyard and thats where im at. the relay i got was put in and nothing changed. the car still makes the annoying buzzing sound. im at my wits end and my mom is tired of lugging my ass around. someone please please help me! i drive a 1990 honda civic hatchback standard with dual point injection and a four speed manual tranny. if i get the spark back i might be able to fix the idle problem, i think that the o2 sensor is bad, but to figure that out i need the car to spark agAIN. AT THIS MOMENT THE CAR DOES NOT SPARK AT ALL please help. thank you.

If the cat is glowing red, sounds like the cat may be shot now too. Check the dizzy coil you may not be getting a hot enough spark and all the gas isn't burining and is getting the cat hot. I am not real familiar w/ the carb. setup on hondas. See what your plugs look like and see if they smeel really strong of gas, if thats the case then either your getting too much gas or the spark isn't hot enough to burn it which whould cause a red hot cat.

i didnt run the car for long enough to necessitate a new cat. i didnt run the carbuerated intake manifold i used the old one. ill check the ignition coil, but would that cause the main relay to make an anooying buzzing sound?
