Fuse 18 goes to the horn relay are you sure that is the correct one? Try resetting your security system and check fuel pressure with a gauge autoparts rent it then scan for codes. If no manual look online ot reset security

If you don't know what fuse it is why did you say that one and just give us ether correct info to begin with. You wonder why people write back ticked off. Your asd relay is connected to that as well check to see if it's bad you can do that on site here under electrical how to repair. Also these engines have a place where harness may wear through at back of head by stud causes problems. Also check your fuel pressure it may be low. Should be 44-54 autoparts rent gauge. Check at idle. Its' fuse 22 btw
