Filled up at Shell today. Always the same station and the same pump every time. I'm just anal about that. After filling up (93 V-Power), I went to grocery store. After getting back into the car ,I went to start it up and it just kept turning over and over. After 4 seconds or so, I turned it off and attempted to start again. It fired right up. I suspect it may be fuel pump but not sure. Filter replaced 1K miles ago. Car was low on fuel but nowhere near empty. I did notice earlier this week I had belt squealing but saw no signs or ware. Could this possibly be related to startup? Voltage steady between 13.6V -13.8v. Idle roughly 700RPM. Was saving money for suspension but I fear that may be put on standby for now. Should I be concerned?
