My cold start thread
This thread will be used to document my efforts to determine the reason my truck has to be plugged in to start when cold.
Truck would not start when delivered by transport company. 25 degrees out and all it would was turn over with no starting. I check engine metal temps and oil pan temp, all were 25*. Used a generator to plug it in and put a battery charger on it. An hour later metal temps in the area of the water pump were increasing, with a shot of starting fluid it started but ran very bad.
Plugged it in over night, outside temp 29*, engine metal temps in the area of the water pump were over 100*, the oil pan was 25*. Checked GPR, first time it did not energize, second attemp it did energize, engine started (this was the start I posted vid on in other thread). Engine ran better than night before but EBPV still seemed to actuate too much.
Replaced GPR and found EBPV sensor tube broken. Did not plug in for the night.
Outside temp 18*, engine metal temps 18*, oil pan 18*, HPOP resevoir 18*, verified GPR energized and tried start, it turned over but did not start.
I have plugged the block heater in and will get temps and try in a few hours. After reading so many other threads on the cold start issue, I tend to believe the issue (other than GP issues) may be to do with oil viscosity in the HPOP resevoir at the time of start. I am looking to see the resevoir temp is impacted by block heater and if that alone changes it from no start to start.
