Car won't start but will crank

rod.bearings · 02-08-2021, 09:37 PM

New fully charged battery just swapped in and the car still won't start.

Last night it had a hpfp code and went into limp mode. Parked it overnight outside at -40c. Now it won't start

Attached code and video. Any ideas? Could the hpfp just crap out? I never had any start issues before.

I'm still learning these engine but it sounds like it could be a bad HPFP. From what I understand in these pump its a O'ring inside the pump that normally fails. The cold weather could have helped it along. You have a way to check the fuel pressure? I have head other member say injectors could leak in the cold and puddle on the cylinder and it wont start put I wouldn't think it would throw those codes. You could check your spark plugs after its been sitting to see if any have fuel on them.
