Quit starting

Have you tried replacing the ASD relay? When a load is placed on it, it may be failing. Here is how it works. Battery voltage is supplied to the ignition coil positive terminal from the Automatic Shutdown (ASD) relay. From that, the Powertrain Control Module (PCM) opens and closes the ignition coil ground circuit for ignition coil operation. Based on that system, either the relay is bad (even though you get initial power), the coil itself, or the PCM isn't providing a ground.

Let me know your thoughts.

That is very possible. Let me know what you find or if you have other questions. I am interested in knowing if that fixes it.

Take care and have a good weekend.

Sounds like a plan. Have a good weekend.

Hi. Here is a link to check the starter. You will need a helper to complete the test, but it is not hard to do.

You cannot bypass the sensor to turn off the light. The sensor sends different signals to the computer to adjust fuel/air mixture. Now for the ignition coil. Battery voltage is supplied to the ignition coil positive terminal from the Automatic Shutdown (ASD) relay. The Power-train Control Module (PCM) opens and closes the ignition coil ground circuit for ignition coil operation. Are you getting any voltage to the neg side of the coil when cranking?

If not, check the power ground. The power ground is used to control the PCM loads for; the generator field, 8 volt PCM power supply, fuel injectors, and ignition coil.

With that in mind, controller supply voltage - The Power-train Control Module (PCM) receives battery voltage (B+) through a fusible link. I want you to check that. The PCM ground is on the right side rear of the engine. See attached pic.

So lets get started. First, I want you to check the ground to the data link connector. Since you are not getting anything from it, there may be a bad ground. Picture 1 shows / explains where it is located. Picture 3 is a better pic of location. (right side, rear of engine) That specific ground provides ground to the PCM pin 11 and 12 and to the heated oxygen sensor. When you check, make sure there is no corrosion, damage, make sure it's tight, and there is continuity between the ground wires and the neg on the battery terminal.

Next, confirm that fuses 1, 4, 5, and 7 are all good in the fuse box (all tied to the ignition switch for different reasons, but you never know) and most importantly, fuse 1 in the power distribution box under the hood. That is what controls the ASD.

If that all checks good, I need you to disconnect the neg battery terminal and then disconnect the PCM 60 pin connector. Reconnect battery. First, confirm ground to pins 11 and 12. Check for power to pin 3. While it is off, confirm there is no damage to pin 9, 19, and confirm continuity to pin ground on pin 5. That is a ground also, but more importantly both pin 5 and 9 are fusible links. Make sure they are good.

Okay, that's a lot to get started with. Run these tests and let me know the results. I have attached schematics for you to follow. The second and forth schematics are of the PCM plug and what each pin does.

Let me know what you find or if you have other questions.

Take care,
Joe

Wow. Does it not always seem to be something we never expected. Regardless, thanks for using the site. We are here to help when you need us. Let me know if you have questions in the future.

Joe

We all appreciate that. It will most likely help another person.

Thanks,
Joe
