Does vehicle ever seem to idle low?
Expert:  Dan replied 2 years ago.
The crankshaft position sensor and camshaft position sensor are common to fail causing hard start, more commonly the camshaft position sensor. Only other thing that would cause this is a weak fuel pump which would cause lack of fuel pressure. Let me know how it goes or if you have more questions, thanks.
