Was this a used ECM or new?

First I put a used one in and I had a problem with no power. So I put in a new one and it ran perfect for about 3 days and then it started bogging out on the freeway

You may have a wiring harness issue here then. Have you checked the powers and grounds to the ECM?

Not yetI'm not sure what it's supposed to read

Simply battery voltage with the key on. It shouldn't be more than a few tenths of a volt lower than the battery voltage.
Ground should be less than 2 ohms of resistance to the negative terminal of the battery.
Is this a 5.3?

6.0 lq4just unplug it and test it from there?

Here is the wiring diagram. Check all wires labeled:
1. GND-ground to negative terminal of battery-less than 2 ohms
2. IGN-key on power-should be whatever the battery voltage is
3. B+ power at all times key off

My 01 Silverado 1500 hd was hit with a bullet that struck it in the ecm. I replaced the ecm and it drove great for about 3 days and then all of the sudden it started bogging out at high rpm. I don't know why it's doing it but my mil is on and the dtc is p1335. Mechanic's Assistant: Will the headlights turn on? Is the battery fully charged? Yes it idles just fine and the headlights work Mechanic's Assistant: Anything else we should know to help you? Well, after I replaced the ecm, none of my windows work and neither does the stereo. I replaced the crank sensor and still no change in power Mechanic's Assistant: OK. Got it. I'm sending you to a secure page to join JustAnswer. While you're filling out that form, I'll tell the Expert about your situation and then connect you two.
