1999 international 8100 won't start

Did you check to make sure you have power to the fuel selinoid? Shouldn't
Take a m11 long to build fuel while cranking are you getting any smoke out of the stack while your cranking it might have a fuel line sucking air

 

Yes, it will look just like this, may be black in colour on your engine. It will have one wire going to it. This is your shut down solenoid. It needs 12v to send fuel to the engine. If you do not have power at that wire with the key on the engine will never start.

 

That is possible. We have seen before that the pump has been wearing out for some time but is still able to draw fuel until it can't anymore one day and then thats it won't start. We will remove the fuel line at the pump inlet and install a test line to a pail of fuel. If it won't draw fuel up from a pail only a few feet away it may be time for a pump. There is a spring loaded disc on the other side of that solenoid that may be stuck. The solenoid is just an electro-magnet that pulls that disc against the spring by magnetism. If the disc is stuck it would cause your no-start.

 

Great glad you got it going
