I forgot to say that everything has checked out per the FSM until I reached the step telling me to check the ECM.Updates:
1) NGK plugs and wires now installed
2) Denso cap and rotor installed
I am following the ON-Vehicle inspection Spark test per the FSM.
Since we have last spoken, The coil came in. I installed it and still no spark. Thinking I may return and purchase an igniter to see if that gets me going. I may have overlooked but I do not see any specifications on checking resistance to terminals with igniter. While the igniter is shipping I am going to dive in to the ECM and carefully check everything as explained starting on EG-231 of the service manual.
@SmokingRocks Am I headed in the right direction here?
The engine needs: Compression, Fuel/Air mixture and Spark to run. We are assuming the compression is fine, know that fuel is present at the fuel rail and it sounds like we've narrowed in on a spark issue.
Based on what you've stated you have tested / confirmed the following on the spark branch:
- Checked, connections (removed, cleaned and reinstalled) at the Ignition Coil, Ignighter and Distributor
- Checked Resitanve of spark plug wires, all resistance was under 25k ohms
- Checked power supply to the ignition coil and ignigter. Verified that battery voltage is pressent at the + terminal on the coil
- Verified resistance of the ignition coil is within spec
- verified resitance of the signal generator is within specs
- Verified the gap in the distributor is within spec
Next check that the IGT signal from the ECU?
I think we need to verify that your distributor is sending the right signals to the ECU. Lets recap how spark is delivered so you can understand exactly why we need to check the distributors signals.
- Starter cranks over the engine which spins the distributor
- A signal from the starter is delivered to the ECM to let it know that it's time to go. THis signal should be 6volts or more at the STA port at the computer. CHECK THIS, you will need to remove the glovebox to access the ECM. Measure voltage between STA and E1 port while cranking
- View attachment 1989983
- View attachment 1989982
- If the voltage signal is confirmed then move to the next step
- The spinning distributor creates pulse signals that are sent to the ECM terminals, you will need to verify that these signals are present at the ECM. These signals allow the ECM to set the advance for the spark. Jump G1 to G-, G2 to G-, NE to G- while cranking, it helps to have a multi-meter that has a memory function.
I believe someone may have tried to install an aftermarket door locking and starting system. I found a non-OEM box zip tied under my dash above the kick panel. I looked it up and found it to be from a manufacturer named “bulldog security systems” I believe particular box this is tied into my door locking system. This could be a possible lead if is has something to do with the ignition which I suspect it very well could have.
