Hey everyone, long time reader first time poster. My mothers integra with 275k miles on it has no spark. I have replaced plugs, igniter, coil, rotor, main relay, coolant temp sensor, checked all fuses, checked all the grounds i could see up top, fuel pump hums and there is fuel at the banjo bolt at the filter. I do not smell gas when cranking and the distributor has juice. Main relay clicks and i have no lights on except abs which i know is due to the internal seals being bad. Im beginning to suspect a bad ecu but im posting here to get second opinions. The engine will not run even on starting fluid. The lack of gas and no spark has pointed me to the ecu. Anybody have any ideas? Thank you.
