I have a 1992 honda prelude 2.0si auto have had ingnition coil replaced and it fixed the problem or so I thought the car started to stall on start every now and again then the problem grew and started stalling whilst driving more so at lower speeds and now it won't fire up at all it cranks but nothing fires up

Also fuel pump is running and main relay clicks as it should be

Replace the Ignition Control Module (ICM):
