97 Ford Escort cranks but wont start.

I'm trying to troubleshoot my parents 97 ford escort, it's a 2.0. At first every now and then it would bog when you started it up but would be fine while driving. Sometimes it would start up and idle fine. Seemed to be an intermitent problem while idle. Then about 2 weeks ago it had a loss of power when accelerating and as of 3 days ago it started bogging down while driving it till finaly 2 days ago it won't even start but it will crank. If you give it gas while cranking it sputters a bit but won't start. I depressurised the fuel line and turned it back to the on position on the ignition and it repressurized so I'm pretty sure it's not the fuel filter or pump. I checked all the injectors and they all read 13.6 ohms. I also tried to check the trigger or pulse to the injectors and when I turned the ignition to on I got 12 volts to the injectors but when I went to crank it over it went down to 10.6 volts and stayed there. I'm not sure if I did the pulse check right or not. I'm using a multimeter for those checks. The coil pack checks out and the plugs all fire. I hooked up my odbII scanner since the check engine light was on but I didn't get any codes reported back. The only thing I can think of is maybe a bad PCM or is it possible the timming belt broke? The timming belt was never replaced and it has 197, 00 miles on it so I think that could be a possibility. What are some things I could do to troubleshoot this further?
