ok so I have a 94 integra ls with 113k, and lately ive been having some trouble starting it up. i just bought it about a month ago, and things were fine for a while, but recently (about a week and a half ago) its not been starting up very well. all the electronics turn on, but when i turn the key itll try and start up, but its just not going. ive had the cap and rotor checked and those are fine, ive had the spark plugs replaced, ive had the fuel filter replaced, ive had the battery checked and thats fine, but its still not going. it does start up sometimes, but then sometimes it doesnt. not really sure what else to check, so if anyone has any advice please let me know asap, thank you all very much your help is greatly appreciated
