I have a 1993 Volvo 434. With EST ignition At first had a no start Replace the ignition module Started right up and ran perfect after shutting it off next time no start again after testing everything ignition on there is one spark and if you hit it just right the engine will run after testing everything I found that when the starter is engaged there is no spark Is there another power supply to the coil during cranking?
Any help would be greatly appreciated
