C15 acert mxs ecm wiring. 2006 KW

Today i had just left the house and i made it bout 2 miles down the road. I was driving at bout 60 mph and i lost throttle, stop engine light comes on, coasted in gear for a few seconds and then the engine came back to life. Then 5 or 6 seconds later it done the same thing. This time it didnt come back to life.

I had my brother pull me back home and put it into the shop. I dumped 911 powerservice in, changed fuel filters and tried to start it. No go. Shot a little either, ran off either and died. Done that a few times to see if it will take off, but it didnt. I thought, well dam, Its not getting fuel or power.

I notice now that the ECM is NOT showing any milege, engine hours, outside temp. Also it showed no oil pressure while cranking the enigine on either. Its like the ecm lost power or has failed. Anyone have a schematic on the ecm plugs so i can check for power? Any suggestions? Thanks guys!!!

 

Thanks @Diesel Dave I did try to check for codes. The check engine light doesnt even come on at all when i turn the key on and/or hold the cruse button down.

My air pressure gauge work, volt gauge works, but thats it. The backlighting does work on all of the gauges though. My truck had been setting all week and when i got in it to start it today, the batteries were way down. It cranked slow, but it did start and run. It idled for maybe 30 mins to warm up before i took off. It ran just fine for the first couple miles then just basically died.

Im at a loss. I need to see what pin numbers to check on my ecm for + power and for ground.

 

Oh by the way, i just replaced all 4 batteries 3 weeks ago. The batteries crank fine and seem to have plenty of juice.

 

Im thinking theres GOT to be an inline fuse between the ECM and batteries, but i havent found it yet.

I just think its very odd that the ECM isnt showing any memory on the miles or hours.

 

I check what i could in the fuse box in the cab. Nothing bad there. So my next step was gonna be start looking to see where the inline fuse for the ECM is. i hoping the ecm isnt gone. I wish i had a test unit to put on it
