    Weak spark on 94 toyota
    My 94 toyota 2.2 stopped running I have checked all relays. Coil primary and secondary ohms. I have replace the TPS sensor and fuel pressure regulator. Fuel pump runs and pumps fuel when cranking and it activates when I jump terminal. I have notice that it has a weak spark. I have also replaced the capacitor/resister that connects to the positive side of the coil after finding it has the inside oozing out some kind of plastic material. It still won't start.

    Replace the Ignition Control Module (ICM) and coil. Bench testing these components is virtually a waste of time.
