1990 Corolla won't crank (663 Views)

My daughter parked the car in the driveway one afternoon and the next morning it wouldn't crank. When I carried it o the shop, it would only fire on two cylinders. My mechanic has checked all fuses, compression, replaced the distributor, cap, rotor, plug wires, timing belt, and everything he knows to check and it still will not crank. I even called the local Toyota dealer and spoke to their Toyota Guru and he is stumped as to why it won't crank. Any suggestions guys? Thanks for your help.
