It cranks but no start. The day before she ran fine. I ran her a bit too low on gas. Filled her up running fine. There was a smell of gas after pumping. I cut her off at night. Next morning crank and no start!!!!! What should I look for? Thanks

Are you getting a Check Engine Light? If so, find out what the codes are. If you don't know how to do this, here is a nice how to.

Also, when you crank the car, does it seem like it tries to catch at all?

It does not catch at all. I will check the codes when I get home.

Ok, then it is possible that it is a RPM (Crank) Sensor or a Cam Sensor. You should have a code if it is one of these. Keep up posted.

Mine has a OBDII port will that work or should I use the procedure?

Before jump to any conclusions such as CPS or anything else, two things you need to check.
1, Do you have fuel? That gives you confirmation of either you have problem of fuel delivery system preventing you from start or not.
- If your fuel pressure(FP)>40psi at the Schroeder valve on the end of the fuel rail, then the fuel delivery is not the one (go to 2).
- If you have no or low FP, do you hear the "buzzing" sound when your key is turned to pos II? (1) if its no, jump your fuel pump relay (2) still no, give a smack at the bottom of your fuel tank see if your pump comes alive (a new pump should be ordered ASAP); (3) still nothing after smacking, check your pump getting power or not and see if it works with direct 12v.
2, Do you have sparks?
-if no, check your codes and post back what you got.
BTW, your OBD I ports will give you a ton more info than your OBD II port unless you have volvo's scantool.

The tank is full. I noticed there was no Buzzing sound from the pump. I just replaced the fuel relay not long ago I assume it is the red one?
