So it was pretty cold this morning, about -35 degrees Celcius. Truck wasn't plugged in last night, remote started it to let it warm up before getting in. I know that it started and was running for about 15 minutes. It had stopped on its own before I got outside and might had been stopped for 5 minutes. Got in and tried to start it with the key, message popped up saying "reduced engine power" turned the key to start it, it cranked fine but did not start, tried two more times no success. Battery voltage was normal around 14-15V but tried boosting anyways, cranks but still won't start. Decided to try plugging in block heater for 15-20 minutes, tried starting it again (no booster pack) started up just fine but engine light stayed on. Went for a short ride and drove just fine (wouldn't go into V4 because of CEL right). Went back home and cleared the CEL by disconnecting the battery. Drove around for a couple hours with multiple stops and starts, starts fine now.
I find it odd that plugging in the block heater for a short while got the truck to start and was wondering if anyone has had a problem like mine or might know what could cause the no start and reduced engine power message.
Thanks in advance.
