Check your oil and see if it looks white to greyish in color. If so, you might have a cracked block. I hope not! Let us know, OK?

hello thanks for your response. I changed the oil. it was black but very diluted with gas. it cranks but hits hard at approx. the same spot like a valve dropped or something just not sure how to check
Ok, Sorry, I am lost on this one but let us know what you find out, ok?
This may be your answer. Sounds like a hydraulic lock due to gas leaking from injectors. Pull all the plus and see if it will turn over. If not tear down is possibly needed.
