Running good quit, cranks good, no spark to plugs, has lights, horn, etc. Don't have smart phone only old laptop, did get some codes, from watching your other videos 24, 26, 21, 71, 19, 62, I'm alone, hotwired the test light to single connect, but have to turn switch myself to get codes under hood, I'm thinking these codes are correct, btw, thank you for your videos, they got me this far, btw green fuel relay on fire wall clicks, but don't hear no fuel pumps sound, fuel gauges both work with key on, the crash shut off with the red button, the button down, with key on the test light is dead, when I ground n test them one at a time, these 2 wires are at the bottom of the unit with the red button.

The inertia switch should have power through it BTW. It is a simple two wire connection. Here are the codes, I would clear them and then try to start the van again, if all of these codes come back you have a bad PCM ground or the PCM itself is bad.

Code 24: Intake Air Temperature (IAT) sensor out of range.
Code 26: Mass Air Flow (MAF) sensor or Vehicle Speed Sensor (VSS) signal out of range.
Code 21: Engine Coolant Temperature (ECT) sensor out of range.
Code 71: EGR feedback (EVP) signal out of range.
Code 19: Failure in the Electronic Control Assembly (ECA) or Electronic Control Unit (ECU).
Code 62: Torque Converter Clutch (TCC) solenoid circuit failure.

I have heard these vans have trouble with the ignition module TFI, (common) Here is the location so you can check it out. Check out the images (below). Please let us know what happens.
