1995 Toyota Camry Ignition

Hello,
I am having a problem with the car not starting, no spark. It started stalling while driving, now won't start at all. I checked the EFI relay and fuses, ignition fuses, alternator, ignition module, pickup coil, and checked dist. Air gap. Replaced plugs, wires, dist. Cap and ignition coil. There is power to the coil. I don't know how to check the IGT signal from the ECM, I don't know where the COR(circuit opening relay) is to test. I have heard that the MAP sensor may be the problem, or the crank sensor. I haven't checked the fuel pressure, but smell gas, (the problem is no spark). Not sure where to turn at this point.
