my grand am will not start it has different kind of spark plugs will that make a no start on the car
Looks like you’re chasing an electrical gremlin here. First, the brand of spark plug may in some cases cause issues with starting. However, beyond brand is making sure it’s the right model and has the correct gap is more critical. The fact that you’re trying to start the car with throttle cleaner is a red flag. This method used to work really well with older, carburetor fueled systems, but with today’s fuel injected systems that are monitored by ECU’s, that typically causes a huge overload of energy, can fry the sensors and put you back to square one.
My advice here is to contact a certified mechanic and have them diagnose the starting problem you’re having, as by trying to fix it, the problems with the Grand Am may have gotten worse unfortunately.
How to Identify and Fix Common car Problems ?

The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.
Too late or too early and the air/fuel mixture won`t entirely combust, reducing performance and potentially failing to start the engine entirely. One of the reasons your spark plugs might be firing incorrectly is due to a faulty crankshaft position sensor.
Having worn spark plugs will cause the ignition system to work harder. Faulty spark plugs can also cause your battery to drain. Harsh weather conditions increase the chance of worn spark plugs preventing the engine from turning over.
As a camshaft position sensor weakens, the ECM (Engine Control Module) switches off fuel and spark delivery that can be a dangerous situation. If you ignore the symptoms which your camshaft position sensor fails, or any other listed here, eventually your engine will not start.
No warning lights or other signs of electrical activity could indicate a dead battery or that the battery cables are loose or corroded. Try turning on the headlights. No lights? Then you have a battery or battery connection problem.

Most of the time, when it’s extremely cold outside, the problem is with the battery and an inability to have enough cold cranking amps to activate the starter and other ancillary components that allow the vehicle’s ability to start. Although worn out spark plugs tend to impact the vehicle’s ability to start, they are usually not the source of cold starting problems. You might want to either replace your battery, or contact a professional mechanic to complete a car is hard to start inspection first; before you determine why your car is having difficulty starting.
A qualified technician, such as one from YourMechanic, would first test for voltage (as well as voltage drop) at the starter when you actuate the starting circuit. If no voltage, that is if the circuit is open, the break in the starting circuit is simply traced.
If there is power to the starter and yet the starter will not function, the starter is condemned and thence replaced. YourMechanic can perform these tests to properly diagnose your starting issue right at your location.
At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.
