Car won't start after sitting overnight?

This problem was noticed on Audi A4 Quattro.

This problem is very common problem noticed in most of the car models.Its a car maintenance and servicing indication.

In this types of cases the engine starts if sprayed stater fluid on throttle body.

But this same problem repeats after car sitting overnight again.So starter fluid procedure is not permanent solution.

If plugs are older than 20k miles, replace them
- if fuel filter has more than 50k miles, replace it
- if coolant temp sensor isn't green in color or hasn't been replaced in 3+ years, replace it.

This are basic possibilities you can try.

In most of cases if car starts by spraying starter fluid ,then issue is with faulty fuel pump and clogged fuel filter.Inspecting this parts properly will help.

Thanks.
