You need to do some voltage checks starting with voltage at the coils.

Your battery is low. You should charge it to 12.6 volts.

Again about the fuel, did you have a good flow from the rail?

We are getting closer to the ECM.

Yes. Had good fuel flow at the rail. 12.12 volts is higher than 12.6.

No, it is not. 12.12 is much lower than 12.6 volts.

Yeah, you're right now that I think about it. 12.12 is less than 12.60.

I saw that. To check the coils, you need a scope to see if the coils are being commanded by the ECM. From past experience, it sounds like the ECM is the issue.

You think I should throw the cam shaft and crank shaft position sensors at it out of desperation.

There are no codes for them, so no.

If either was an issue it would set a fault code.

You are going to need some extra help to track why it has no spark.

Do you have a local shop that can at least do a diagnostic?

I bought an ECM when the truck first stalled out. I kinda assumed it's the computer. Truck was running beautifully before it did this.
I'm thinking about just installing the junkyard ECM and paying someone to program it.

Try it and see. It depends on what it came out of to see if it will run.
