This is a very common problem with GM vehicles in general.

The first thing I would do is check the fuel pressure regulator. It is located about in the middle of the fuel rail on the drivers side of the engine. There will be a vacuum line attached to the top. Remove the vacuum line and see if fuel comes out of the nipple. If it does the regulator is bad and needs to be replaced. Sometimes you will need to start the engine or cylce the key a couple of times to build pressure in the fuel rail before gas will come out of the regulator.

Why does my car get to its normal temp and cut off?


Does it immediately restart or is there an extended crank to start it back up? Is the check engine light on? If so, have the codes scanned to see if any problem areas have been found by the computer. A cold engine requires more fuel and as the engine warms up, fuel is trimmed back/reduced by the computer. You may have a vacuum leak causing the stall/dirty throttle plate/ or it could even be an electrical issue to/from a sensor

Engine starts when cold but won't restart when half warmed up


It's probably still a problem with the ignition control module/coil, with a circuit in or attached to it heating up as the engine warms, and then the circuit opens when stopped and it starts to cool. As soon as the engine sufficiently cools off, the circuit would revert to a good connection. I would carefully check the connectors and wiring on both sides of the module, and then possibly trying another module.

Crank but does not start (Error code P0642)


p0642 = sensor reference voltage a circuit low voltage
p0300 = means random misfire
check firing order connections and must be in place.
check also cables especially the high tension cable and coils for required resistance.
primary = 1.0 to 0.5 ohms
secondary = 900 to 11,000 ohms (as requires per model)

Starts when cold but once it is warm and is shut off it won't


Hi!
Looking at your brief description can I guess that when warm the starter turns slowly? as if a flat battery?
If this is so then the starter windings and armature are possibly cooked??
Have you recently tried cranking the engine too much? or with a poorly charged battery?
When cranking the starter gets very warm and if not left to cool after 5 seconds of cranking can cook the wiring/armature internals of starter.
When your engine is cold the Windings/armature are too so will turn easier, but when warm all internals are expanded so more drain and heat! then causing the starter to revolve slowly taking a lot of power from engine and ignition circuitry.
This can also be caused from trying to start a vehicle with low battery, Volts go down Amps go up cooking/frying the winding/armature.
I am suggesting this as all I have to go on from the description STARTS COLD BUT ONCE IT IS WARM???? I hope this helps,
If it does please remember to press FixYa button as I have taken a lot of time to post the response.
Good Luck!
