Trying to pin this issue down as there is zero info out there from my searching.
Here's the situation:
After putting the key in and going to the run position or trying to start the vehicle, it cranks, but does not start.
After about 5 seconds the security light comes on solid on the IP.
My ‘10 got the good crank, but no start issue. No codes! I went through all normal suggestions. Replaced RPM and cam sensors, tested IPDM, checked fuel pump, and was beginning to believe it was an ECM issue. If it started it would run perfectly. I did notice that all the dash gauges would...
TLDR: Car wont start in cold or medium weather, battery is good, heat gun on ECM didn't help, only starts with a jump pack even after being driven for 2 hours+ and alternator charging battery.
-Gets a spark
-Has fuel pressure
-Requires a jump pack to start (even @50 degree weather)
