2003 Toyota Corolla Q&A

2003 Toyota Corolla Question: How would I know if i need a timing chain

Car will crank but will shut off; it stopped cranking installed a crank sensor and it started back cranking but wont stay cranked; when the crank sensor was removed the old one was bent or dented like something had almost crushed it. Could a loose timing chain cause this? -
Answer 1
poss tensioner issues inside timing cover which will make chain loose.pull valve cover and look with flash light and see if chain is loose or jumped time -
