Starting Probs

Alright i own a 90 civc dx, and i have been having starting problems. It doesnt happen all the time, but probably half the time im driving it. I will turn the key the car will start for 2-3 seconds then the engine shuts off. After 5 minutes the engine will turn back on. I had my main relay replaced a while ago, its winter where i am so i dont see that as the problem. I was thinking electrical, but im not sure. Any comments or suggestions?

power? fuel? spark?

this happens to my car like once every 2 months, ill start it and it'll idle funny and then die, and if i try giving it gas it will just kill it out faster, then it'll not start for a min or so, and then its fine again.

Im stumped on it, but also havent looked into it to much. First thing I would check is coil and ignitor, and then fuel pressure.

Alright ill check those, any other ideas?

i had a problem like this and it turned out it was the coil giving off weak spark. so check your spark like super said
