My wife call me at work and tell her truck stopped. So I leave to meet her and AAA to get it towed to the shop. Get there and turn the key seems like the starter is bad. After beating on the starter I notice the starter is trying to do something. So just for kicks I check the Oil. Wow... the stick is not even wet. So I try turn the engine with a large screw driver then with a large pipe wench. Could not turn it. After work I am going to pull the plugs and put some Lucas Oil in there and let it sit for awhile and hopefully it will tunr over. Does anyone have any ideas about unlocking a engine. This is 97 Grand Cherokee with a 4.0L... I have only been telling her to get an oil change for 2 months now... We were suppose to go looking for a car for our dauther Saturday. Are son just got a 05 Sebring last year for his 16 birthday. This is offically my longest post ever...
