P1441 GMC -

Question

would this make the vehicle just stop running and not start? was in cc @55 and just quit. the only other code was a P0137 which is smog related pulling my hair out lol can hear fuel pump come on have not checked pressure yet, any help?

Answer 1

P1441 Evaporative system flow during non purge

P0137 02 sensor circuit low voltage (bank 1 Sensor 2)

Neither one of these code will not cause a no start. Hearing the fuel pump is a good sign that more than likely the fuel is being recieved, If your scan tool gives live data use the RPM data as you crank the vehicle the RPM must register more than 250 RPM in order to start, . Why ignition module are more prone to fail is the lack of a proper heat sink applied, When it fails it does not set a code, There is also the  the  crank position sensor which  is more of a misfire detection on this year make and module.
