Hi, I own an accent CRDi '03. My problem is that, engine wont start in the mornings. But it does start on jump starting and push start. After that it runs normally and starts normally. I've checked battery it is good. So what would the problem? And one more thing I've checked for errors, it shows "WTS heater plug relay fault". Sorry don't remember the code. Please help me out. Thank you.

Thank you for your answer. But before jump starting I used my cars fully charged battery itself, but the engine doesn't start. So, I followed jump starting and it worked. Then I checked my car battery it was good. After reading your answer, I asked my mechanic, he checked all the electrical wiring and alternator, both of them are good. Yesterday morning we tried again, but the same problem, the engine doesn't start. So my mechanic took out the crankshaft sensor, cleaned it, removed the rubber washer attached to it, and put it back, and the engine started. So the problem was with the cranshaft sensor's rubber washer. Now my car starts normally in morning. And the problem is solved. Thank you for your answer.
