Default 01 RX300 only starts with code reader

I have been having hard starts, now no starts unless my code reader is plugged in. Cranks but no start without code reader, with it in, Ill get is started albeit a tad rough at first then after warm up, runs and idles perfectly. Sometimes check engine light is on with P1760, P1656,P1351 then others no codes at all. I checked all the ground under the hood but I am afraid this is pointing to an ECU. Any ideas on problem or best source for another ECU? Thanks so much!!!
