Hi yesterday the 3rd february car wouldn't start ai put a brand new battery and would hold the gas pedal while cranking it and after 25-30 seconds it started and held rpm. now today the 4th it doesn't start but it is extremly cold outside -27 degrees celsius, I tried it today but it only cranks, feels like it's about to start but then it dies and it sounds like starter is having some trouble. I was told to check the fuel pump relay and to replace it and also check my fuel pump ground behind the spare tire.
