I have a 1995 Dodge Neon recently I went on the highway and was doing about 65 miles or so soon after something went wrong suddenly and car started slowing on it's own and could not get back up to 65miles. Like 20 seconds later engine light came on and car started to shake. Couple of days later started smoking from engine and muffler. Took motor to machine shop and replaced it but wont start. Timing seems correct but it still wont start,engine won't turn over. I don't know what else to do it's been 3 weeks of trying to fix my car and still it won't start. It does sound like it's trying to but so far no luck any advice would be helpful. Thank you so much for your time.
