I would rec to check for fuel trigger. Fuel trigger is the signal from the computer to the injectors. You would use a tool called a noid light. It simply plugs into the injector connector after the fuel injector is unplugged and should blink when the engine is cranked over. It looks like this.
Well the pick up inside the distributor can be bad. This is what tells the computer that the engine is turning over and for the injectors to fire.
The distributor has a separate coil which connects to the rotor through a high tension wire.
The distributor uses a magnetic pick-up assembly located inside the distributor consists of a permanent magnet, a pole piece with internal teeth, pick-up coil, and a hall effect switch. When the teeth of the timer core, rotating inside the pole piece, line up with the teeth of the pole piece, an induced voltage in the pick-up coil signals the electronic module to trigger the coil primary circuit. The primary current decreases and a high voltage of 35,000 volts is induced in the ignition coil secondary winding which is directed through the rotor and secondary leads to fire the spark plugs. This system incorporates a hall effect switch which tells the ECM when to fire the next cylinder. The capacitor in the distributor is for radio noise suppression.
This distributor also features a longer spark duration, made possible by the higher amount of energy that is stored in the coil. This is desirable for firing leaner mixtures
K... I will be here!
Lets check for the ground signal trigger at the signal wire coming right out of the computer.
ALso, lets pull codes again
This connector is used in the assembly plant to connect a computer for checking of the system to see that it is functioning properly before shipping the vehicle. To obtain trouble codes with the ignition switch on and the engine either stopped or running the "test" terminal in this connector should be grounded. The "test" terminal should be ungrounded when starting the engine or the "Check Engine" lamp will not function properly. Refer to Figure 1.
ALso, here is a flow chart to help you diagnose the no injector pulse.
Circuit Description :
This chart should only be used if diagnosis in CHART A-3 indicated an injector circuit problem.
Test Description : Numbers below refer to circled numbers on the diagnostic chart.
This test will determine if the ignition module is generating a reference pulse, if the wiring is at fault or if the ECM is at fault. By touching and removing a test light, connected to 12 volts, to CKT 430, a reference pulse should be generated. If injector test light blinks, the ECM and wiring are OK. This step tests for 12 volts to the injector. It will also determine if there is a short to voltage on the ECM side of the circuit. This test checks for continuity to the ECM.
