Spark Plugs,my grand am will not start it has different kind of spark plugs will that make a no start on the car

friends car car was running okay he decided to change spark plugs and problems started he has different kind of spark plugs it has a delco , auto light, and denso and we don't have any codes on it… it will crank but no start it has spark and fuel pressure about 45 psi we were thinking maybe the no start was because of spark plugs ? if we spray throttle cleaner the car will start and will run fine and will start again when the car is warm without spray.. come back in the morning and it will not start does not have security light on what do you think we check more on it or have you hav
