Could be ignition or fuel.
You would check for fuel pressure when it fails to start. The fuel pump or pump relay could be failing when hot.
Same thing with the coils and ignition module.

SOURCE: Check Engine Light on -- No Problems Found

You don't have to worry about P0411. But you need to fix.
because the vehicle will burn more gas...
Let me Explain a little bit. of the SECONDARY AIR INJECTION SYSTEM.
Your vehicle use a Vaccum Electric pump. to reduce the HYDROCARBOM EMISSION , During a Cold start the System forces filtered fresh air into the exhaust stream in order to accelerate the catalystic operation.
The IAr is send to the exhaust passing from a check valve.
The code P 0411 , Can be a restriction on the hose coming from the Air pump to a Exhaust. or The hose damaged or pinched.
But the first step is check the operarion of the pump.
Check the Air pump relay. and fuse.

The pump Is located on Left Front Frame Rail, Forward of Fenderwell.

P1660. This code refer to a : Excessive Current or Voltage ON the system.
Check The ALTERNATOR for proper Voltage charging.
If the Alternator is charged more than 16v. replace the alternator.
Remember if you gave a Jump Cables of any time or day.

Any of this will the code P1660 come..
After you check the Charging system. And detect that everything is in order, Clear the light.

PRINT THIS COMMENT and give to your mechanic....

I hope this will help on your problem.

SOURCE: 04 pontiac grand prix wont start.

first remove the battery and take it to a auto parts place and have them check it. move on from there. if the battery is good the do a starter draw test. take a meter and hook it to your battery. now have someone try and start the car. if the voltage on the battery drops from 12.8 to below 9 volts then the starter is bad. if the voltage doesnt drop much at all then its prolly the solenoid both of which require starter replacement since most solenoids are on starters. if still nothing then check ignition switch. but before anything else ensure vehicle is in park. if it is in part use a meter to test neutral safety switch.

You need a steering pump. or you could have someone rebuild the one you have for half the price.

SOURCE: 2002 Pontiac Grand prix wont start; unable to remove key

On many cars, if the battery is dead, it locks the key in the ignition. Put a battery charger on the car or replace the battery and give it a shot.

Good luck.

SOURCE: car shuts off while driving wont start up

You need to replace your crankshaft position sensor located by the harmonic balacer. These sensors heat up and cut off the engine until the sensor cools down. This happens with age and it is not specific to GM.

I would have the control module tested. Some parts stores can test them. If that's ok, you might have some bad injectors.

2001 grand prix gt freaking out!

Hello and yes this is a major noise. I would check your oil now right before you ever start the oil again. This noise may have been your engine locking up from really low oil levels and excessive heat from a lot of driving. If this is fine contact me again and we will address more problems if their is more. Thank You.
