What happened after replacing? What did it control? What cavity did it work from?

Relay located on firewall, near brake fluid reservoir. Recharging battery now. Will try and start it when battery fully charged, tomorrow. These are the new replacement parts I have had installed. Spark plugs and wires, coil pack, fuel filter, alternater and belt, battery, upper and lower oxygen sensor, camshaft position sensor, crankshaft position sensor, general purpose relay. Problems having-. Idle rough, but usually will stay running. When driving though does run smooth and then (check engine light comes on/sometimes on acceleration-flashes) there will be at times power loss and stalls. Will not start.

Ok, 2 things, first what is the fuel pressure?

Throttle bodies are common failures for the rough idle. Check for vacuum leaks.

Check compression as well.

Compression checked out fine, I tried to clean throttle body and did the vacuum leak check and fuses. Tomorrow will try checking with code scanner. Again
