Thanks to all who tried to help. With the aid of buying and receiving the main or ignition relay, finally able to find and replace it. Elated that sparks have returned but still no start with cranking. After being left alone for a long time, like a day, at first start, the engine would try to turn over but could not. Subsequently, cranking produced nothing. This has been the case since engine quitting during idling in 12-20. Seems to me that the only culprit left is timing belt jumped several teeth during idling which I find hard to believe. Any ideas before checking out the timing belt. Parts replaced so far starting from the latest are spark plugs, main or ignition relay, crank sensor, cam sensor and ignition module. Thanks so much.
