Car turned off while driving, got a jump drove home and car will not start. Car sounds like it wants to start. Replaced the crankshaft sensor put car together and it started but sounded rough at idle after about 2min. Car turned off. Restarted car 3 times and each time it turned off. Now it's back to it will not start status and no spark is going to the spark plugs. What can I do next to fix the problem?
