Car won't start OR even roll .. seized engine?

My 92GS won’t start - replaced things like MFR, ignitor, coil, etc to no avail. Decided to just get it towed to the shop so a professional can take a look. With my fathers help I tried to push it out of the driveway and on to the street for the tow truck, and it absolutely will not budge … is there any way that this is Not a seized engine? How would I test for that? Total noob here.

the transmission is engaged if the car wont budge, or the e-brake’s are sticking in the rear. has nothing to do with the motor…to test motor-check compression in all the cylinders, pull a plug and hold it against a ground and make sure you are getting spark, and/or make sure the cams are turning (timing belt not broke).
