I have a different engine but had a similar problem with extended cranking and for me it was the crank position sensor.
We have 2 Impalas with the 3.8L. The 2001 now has 103k and the 2004 has 120k.
In Sep-06 at 92k the 2001 suddenly started cranking longer to start. This car had always started on 1 crank. The problem started 1 week before my 6yr/100k extended warranty expired.
Dealer replaced fuel pump and ignition module under the warranty but that didn't fix it and they couldn't duplicate the problem and of course no codes.
 
Then it started stalling out intermittenly too, but it always restarted. My wife only does local low-speed driving and it seemed to stall out when it was cold, like the first drive of the early morning, after going a few miles.
Both problems occurred randomly for 2 months and I spent many hours searching the net for a most likely cause.
Finally it stalled after going 100 feet - her first start after work- and wouldn't restart. Towed to the dealer and left it there for several days for them to try to duplicate the problem.
 
I had seen in my research that the CPS could be the problem but the service mngr (who was a very good) said the flow charts don't point to the CPS for the 2 problems when combined.
I said to replace it as a last try because we didn't have a drivable car anyway.
End of story is they replaced it at no charge, and the car's been fine for 2.5 years. I got lucky - it could have been an intermittent electrical problem.
 
Repair history for the 2 cars:
2001 - upper intake coolant leak and cat converter (Chevy warranty), thermostat, fuel pressure regular, one rear ABS sensor, one front wheel bearing assembly, blower resister, fuel gauge sensor and the crank position sensor.
2004 - I drive this one 500 miles a week - one oxygen sensor, a thermostat, one front wheel bearing assembly, and a slow leaking lower trans coolant line.
 
Overall, not bad for 223k total, and if the CPS had been diagnosed quickly, no major problem issues. They also get serviced - fluids, filters.
The cars look good, still feel solid and always plenty of power.

I'll keep my eye on the starting issue. So far it has always been reliable and never left us stranded. Then again, it's only got 40K on it. It is lucky to see a 10K a year. However it is only the the 3.4 How I wish I would have bought that gorgeous used 3.8 LS Impala instead of my NEW base Impala, but what's done is done. It's still been a good car.

The DIC is the Driver Information Center. It is what displays all the info such as your check engine light, idiot light for the oil, battery, security and what not. It is the box in the right hand instrument bezel at the bottom. It is square and pixelated to change to the different icons to depict what ever needs to be depicted.
 
Not sure what would be causing your problem, but I don't think it has anything to do with the DIC?

oil change time... by the_big_al

time for the once a year oil change on the Imp... Since it rarely sees over 10K a year (it's a 2004-bought in October of '04 and only has 42K on it), I run Mobile1 and change it once a year. It was that time today. The only caveat?? Took me longer to change the air filter than it did to change to oil....
 
oh ya - I also flushed out the coolant too.

Bought a used 2003 Impala 3.8L in March 2009. Service Traction System light goes on often, with ABS light and Trac light. Hub sensor wires are perfect-no oxidation. I ignore it and it does not affect driving. Wont take it to a GM dealer to pay $$$ then have the same problem 2 weeks later, like so many blogs describe. Cant find a GM Tech Service Bullitin on this - must be one.

I have a 2003 Impala 3.4L with 118k, ABS light and Trac light come in when I accelate the car very gentle which does not make sense to me. I agree with you.

Did you ever find a resolution to this problem? I have the exact same issue, same stain on the hood cloth, and same area wet on the radiator. I can't catch it in action so I haven't a clue.
