checkenginechuck :
Watching these all now. Just for info the 3 volts is probably a biased voltage and the meter might not be able to pick up the ground pulses if they are there

Is that a trigger line per injector?

Any codes

your voltage on the ground sounds like bad ground

Chuckie :
sounds right. possible problem in the PCM but how's the ground to PCM.

got crank sensor counts?

Connect the injector and then check while back probing

I’ll show my tech in the morning, we have fixed a ton of these cars with weird issues.

Yes, a Powertrain Control Module (PCM) can overheat, and this can lead to engine shutdown as a protective measure. PCMs, like any electronic component, generate heat during operation, but excessive heat can cause failures. Overheating can result from various factors, including software issues, short circuits, power surges, or environmental conditions like moisture and extreme temperatures.

Back probe it or pierce the wire when your measuring voltage instead of unplugging it from the car. Should have battery voltage on the trigger side but you really need a scope to see if its getting the pulse. The 3v might just be a biased voltage when the circuit is incomplete.

Because it’s all the injectors, it has to be something with the PCM. Either the PCM is commanding the ground issue, or there a ground problem inside the PCM or outside. That’s all I got.

There was an extended coverage for the battery ground cable causing multiple issues. Sounds like a ground concern. Will it light a noid light when it’s a no start ?

Check for corrosion at ecm between injector terminals and coil terminals.had a few

Make sure the ignition B+ side of injector plug will light say a seal beam headlight to battery negative, just to be sure

My tech said sounds like a bad ground as well

Load test the ground side of the circuit from the pcm to injectors. Make sure it can carry the load.

Check the ground to the pcm with a test light clip on ground and the tip on the case and crank it. If the test light lights up dim check the ground eyelet cluster on the front driver side of the tranny and the eyelets I believe are near the rad support.

I'd be looking at those blocks grounds.
