I find in my haynes book , jumping the hall effect sensor to make spark on coil , a try and nothing !??I do not understand which wire you think you need to move in the bulkhead of the firewall?
In post #14 I gave references to 2 wiring diagrams; one for 1989 and one for 1990 - 91. You need to print out both diagrams. Start with the 1990 - 91 diagram and check and find the counterpart pin with the same color wire and description on the 1989 diagram. It will be in a different pin location. Check all pins on the 1990 - 91 diagram. You will find one on the 1990 - 91 diagram that is NOT on the 1989 diagram. Identify that pin. It may be the solution to a no spark condition.
To create spark in this throttle body injection, the PCM must receive a timed pulse signal from the distributor. When the PCM receives this pulse, it interrupts the current flow (removes the ground) from the primary circuit in the ignition coil. Interrupting the electrical current flow in the primary winding causes the collapsing magnetic field to induce a high voltage current in the secondary ignition coil winding. This high voltage current then travels through the spark plug tower, to the distributor center port, onto the rotor coil under the distributor cap and to the appropriate spark plug tower which carries high voltage charge to the appropriate cylinder spark plug. The high voltage arcs across the spark plug tip and fires the air - fuel mixture.
You need to check the wiring and distributor pickup and make sure it is generating proper pulses. No pulses from the distributor then there will be no spark. It is also possible that the distributor pickup sensor is generating pulses but internal circuitry has failed in the PCM and it cannot control the ground for the coil.
