If the car cranks runs good I'll drive any where when I turn off want crank

Google > 91 Civic main relay .. Review the results page .. Happy motoring! .. Tomorrow will be a nicer day to work on it!!

the main/fuel pump relay is bad. when it's HOT inside the car it will crank but not start until the relay cools off..IF the check engine light does NOT CLICK when the light goes off,it ain't starting! Part Number: 19257>>>$53.99 at the ZONE...rather than removing the bracket,just pop the guts out after unplugging it,and pop the guts out of the new relay and put it in the old bracket/housing....copy and paste the link,watch the video..this is an Accord but same as civic...
