1999 international 8100 won't start

I have a daycab with a m11 that won't start. i have not had any problems with starting since i have had, but i let it sit for a month with out starting it in the cold, the block heater was not plugged in . i have charged the batteries and plugged it in . it turns over fine but won't start. it will try to run if i spray either in the air tube

 

where would the ecm fuse be located ? i opened the drain plug on the longest fuel filter, i let drain for a minute, if lost prime would either help regain it ,if not how do i regain the prime

 

thanks for the help, i have a fuse panel under the drivers side dash, where would the fuel solenoid be ? i have a test light . this is my first time owning a tractor. i also have a thick cable in the battery box not hooked to anything . it has power to it and is thicker than all the other battery post, it is heavily corroded, no hole at the end just a short nub

the tach is working , i found three inline fuses under the truck all good, i removed one of the small fuel lines on the driverside block nothing came out not even a drop
