engine starts for 3 seconds then stops
That sounds like a security system problem. Any dash lights on?
check engine light is on and was on for 1 week i checked all fluid levels , oil level is slightly high
Have the OBD2 codes read to know what is going on. I would not worry about the engine oil.
i live in a forest miles away from a reader is there anything i can bypass to get it going
You can't bypass the security. Buy or borrow a code reader. They are less than a $100 on Amazon.
Try to get someone to jump start it.
