Ok please bare with me because I'm typing this off my cell. A few days ago I'm driving and the car just dies at first I thought I jumped timing made since the way it just died.

90 civic 4 door no mods

I run though everything and I find out no spark. So I mess with a few things and pull the same dizzy off my buddy's car and it starts, woo whoo right no .

I buy a rebuild dizzy from advanced and put it on the car won't start so I put it on my buddy's car and his starts so we know my dizzy is good.I try a few times this mouring checked fuses and its starts woo whoo right, no again I ran it for a few mins and turn it off jump back in it again and now it will just crank again

Could this be my main relay ?

Please help!

Thanks help will be rep'd
