Hot Starts?

[FirstGM]

Hi Guys,

Just bought my first GM vehicle 2 months ago, it's used 2000 GMC 6.0L 2500 Pickup with 150 000KM's.

 

After the engine warms up I notice that it idles a bit rough. If I shut off the motor and try to start it again the engine cranks longer before it fires and when it does finally fire it is a rough start.

Curious to see if this is a common 6.0L problem, and what the fix is.

 

Thanx in advance!

Step 1,

 

Always check the codes. Always. Always.

Take the vacuum hose off the fuel pressure regulator and check for gas.

The truck has not thrown any codes yet, and where is the fuel pressure regulator located?

Thanx
