B2150 Won\'t start

I have a problem with my B2150 in that it will crank, but not start.
I was running it and stopped for lunch. It has run fine for about 8 years with no problems. It has about 300 hrs on it. I went to start it after lunch and it would just crank. No smoke, no ignition
, just cranks.
I opened the hood and much to my surprise were 2 dead mice near the injector pump. After changing the fuel filter(it was very dirty, it was last changed about 2 yrs ago) I opened the bleeder valves and tried again and it still would not start. I can see the bladder pump that is pumping to the injector pump is getting fuel. If I disconnect one of the lines to an injector, it gets no fuel. I've checked the shutoff valve that controls the injector pump and it appears to be operating
correctly. i.e. is in the correct position when I'm cranking it.
I've checked the voltage to the glow plugs and its getting voltage. I haven't checke the glow plugs, because it appears I'm
not getting any fuel to the injectors. Can the injector pump get clogged? At this point I'd like to take the injector pump out and inspect it, but I can't seem to get it out easily. Does the engine
need to be in a certain position to remove the injector pump?
Stumped and not a mechanic.

I would still bet the fuel solonoid is not functioning correctly.

Re: B2150 Won\'t start

There is a stop handle on the dash that works in conjunction with a solenoid near the injector pump. It appears to operate a flapper type switch below the injector pump. The flapper switch has a STOP arrow on it and when the stop handle is pulled all the way out, it puts the flapper type switch to the left(STOP). I can't seem to find any other type of device near the injector pump that would stop the flow. Is there another fuel stop solenoid besides the one I'm talking about? When I turn the key, this solenoid engages and pulls the flapper switch to the right(not in STOP)....other thoughts?

Re: B2150 Won\'t start

fwiw, I was able to figure the problem out.
The injector pump was clogged with contaminated fuel. By blowing compressed air thru the pump while cranking it, the contaminations were removed.
