starting problem on 2008 d4d yaris

[georgeg]

My car problem looks very easy. when i tern the key on accessories, check engine light and glow plugs light don't come on and the car wont start( cranking but no starting). All the other lights come on every time i turn the key. If i keep turning the key back and forward check engine and glow plugs lights come on and the car starts very easy and runs perfectly. When is hot outside it can take 10-15 minutes of turning the key before check engine light comes on.Does anyone else encountered this problem before? Toyota tech couldn't find what is wrong with it .
