Have a Mazda 62 GT 2.0L. It will not turn over. or start up. It ran fine and over night would not crank anymore. I have replaced the Fuel pump. I think a computer is missing from under the Driver side seat. I need to confirm this though. does any one else have teh same kind of car and can tell me if the computer is under the Driver side seat. If it is not then could the Problem be the ECM under the dash. Thank you.
