My acura only starts every now and then and I can't figure it out

Fuel pump relay has cold-solder joints and needs to be desoldered and then re-soldered.they hide the relay BEHIND the fuse panel down by your left foot if you are sitting in the drivers seat. you have to lossen the bolt on the fuse panel, and you will then find the relay tucked behind the fuse panel , between the fuse panel and the wall that the fuse panel is mounted on. the hide the thing, why I don't know. repair or replace your relay, that should make the engine run again. hope this helps
