'02 Echo cranking but not catching

[tmontague]

My fiancee went to start her '02 Echo this morning and everything turned over but never caught. She tried a few times and then left it. I am at school and will not be home until tonight so I cannot check for codes until tonight where I'll post any new info I learn. Her car always has an illuminated engine light due to a P0420 (cat converter) since she had a plugged PCV valve a year ago and it was burning more oil than normal and putting it into the cat converter (car runs smooth though). I won't know if there is a new CEL until I hook up my ultra gauge later tonight.

I drove the car 80km round trip last night with absolutely no problems and it had been parked overnight for about 9 hours. It is ridiculously cold here right now with my Yaris coolant temp reading 2 defrees F on start up this morning. I ruled out battery, ignition switch and starter as it turns over fine, just doesn't catch.

My thought is a bad fuel pump. Has anyone seen an issue like this before and has a recommendation where I can start to look to figure this out. Any easy ways to check any recommended areas? I'm thinking of turning the ignition to ACC and listening for a fuel pump noise to diagnose the pump. Thanks in advance guys
