So i bought a 89 prelude si b20a5 dohc. If i go out after car sits for like overnight it will fire up for like 3 seconds then die n then has no spark i checked black yellow wire going into coil on top conector It had 12v i checked blue wire on ignitioncontrolmodule connector it had 12 volts this was with key in on position. And the little box that bolts to coil bolt that has 2 wires one going to distruibter i checked the one going to distruibter while turning over and it had like .3volts while turning over. When i put key in on position the check engine light stays on doesnt go out does that mean bad ecu or maine relay ..... And i dont see any flashes above computer. Please help
