91 hb starting problems

I boughta civic hb ran fine but the next day i took it to get an oil change it was run fine .they started it back up and left it running out side i drove 100 feet or so to a car wash ,left it running to wash motor but it died before i could do so . it wouldnt start back up .check spark didnt have any. i put a distributer cap on it it started up and drove two miles and died again cant get it to start again.im thinking its either main relay or ignitor. please help if you know what it could be thanks

Check the coil in the distributer. if it is not that, then it prolly is your main relay

Did you replace the rotor too?
