2003 Nissan Sentra turns over but will not start. It has no spark at the plugs. Replaced Crankshaft sensor with no change. Used old Crankshaft sensor to replace Camshaft sensor (same part) with no change. All fuses look good. Can hear fuel pump when starting. No engine codes that I can see. The engine was very clean when I received the car.
The lady I am helping (owner of car) informed me it all began with her engine overheating. She said someone took a look at it and kept it for 3 weeks. This person was only able to work on it off and on. He took the head off and checked it out. I understand everything looked ok. There was no answer for why it overheated. She got the car back and it ran fine for a week. Then it began to hesitate on acceleration. The engine would die at times but she was able to restart and go. Then it just got to the point where it could no longer be started.
I am just a shade-tree mechanic looking to help the poor girl out. Do you have any thoughts on next steps?
