I don’t know if a mechanic to recommend it’s been a while since I read up on no start issues so I don’t remember which symptoms are related with which parts. I know that crankshaft and camshaft position sensors can be problematic as well as the relay control module. I had my RCM rebuilt and put in new sensors before I had a problem and keep the originals as spares. I did have a warm starting issue which was caused by a failed check valve in the fuel pump.
