Ok heres the deal. Put a b20 in my 91 CRX Si. I was getting to fuel, so i replaced my main relay and now i dont have spark. i switched my dizzy with my buddies and i still have nothing. i tried grounding the plug and cranking it to se if it sparks and i got nothing, so i am assuming no power to the Dizzy. I checked all fuses too and all are well...... i think i may be missing some grounds, will that cause it not to fire?

 

Thermostat housing ground on there?

 

yes... missing or bad grounds will cause a no start condition

 

missing a ground can skr00 you.... thermo as mentioned, valve cover, transmission, and make sure the battery/tranny ground strap is fastened to the frame rail tightly. are you still running obd-0 or have you chopped up some wiring during the swap??
