Cranks , doesn't start , randomly. Always starts first thing

Customer Question

cranks , doesn't start , randomly. Always starts first thing time each day.
JA: Does the engine turn over? How old is the battery?
Customer: It cranks fully.
JA: Tell me a bit more about what's going on so he can help you best.
Customer: starts each day. After subsequent trips during the day may crank but not start . Will eventually start after waiting 15- 30 min with multiple tries.
JA: Are you hoping to fix this yourself?
Customer: Have already serviced it , no codes . Replaced fuel pressure regulator and relay.
JA: Is there anything else the Audi Mechanic should be aware of about your Audi?
Customer: 110, 000 miles . 100,00 mile service was done at that mileage. Leaks a little oil.

Welcome, I'm Chris (aka Moose). I normally log in after 3 pm central everyday. Please let me know exactly what you need from this conversation so I can provide EXCELLENT 5 STAR service.

After it starts in the morning, does it run fine?

If shut off later in the day, it will not start till it cools down?

Can I get the year, make, model, engine, and a brief description of your skills?

Thanks Chris

After it starts in the am and any other start , it runs like a fab Passat that it is. I love this car! The crank , not start problem occurs randomly , not every day , although I make several stops throughout the day. When it has occurred - I have been able to restart the car within 3-10 min after attempting several (5-7) starts ( all full crank no start). 2002 VW Passat V6 GLX 4-motion 2.8. I have had the fuel relay sensor and fuel pressure regulator replaced without a cure. Car does not overheat , no codes on computer, either. Today, had air filter checked and a very dirty air filter "strainer" ( found on certain models I was told) was all that required cleaning. Could this have been the problem?

I'm hoping that someone like yourself has encountered this in similar engines. There are many of these out there on roads with many more miles on them. Thanks.
