Hey guys, I recently purchased a an m1008 cucv. It is currently still wired for 24v as I cant really afford a 12v starter, blah blah blah. Anyway, trying to get it started. It has a new fuel filter, dropped the fuel tank, cleaned it out, its got about 10gallons of fresh diesel in it, replaced the rubber fuel lines because they had a buncha little pinholes. Anyway, I read on this site to unhook the return line from the injector pump and put low pressure air on it (I used about 5psi) and that pressurized the system, pushing fuel up through the filter, and seemed to do a really good job at priming the system.
So I turn it over & over and it doesnt even attempt to fire. So I take loose one of the lines on the engine side of the lift pump. I am getting good fuel flow there, and if I had to guess I would say ~5-6psi worth. However, at the injector I am getting almost nothing. I get a little drip basically, more like a trickle. I pulled the return line off the injector pump and tried turning it over and I just get a little drizzle out of the return line (basically the injector drip x
I noted that there was a relay or solenoid click on the injector pump when I would switch the key to the on position. I was going to check and see if I had power at the injector pump, but undoubtedly it is 24v (I thought the starter was the only 24v accesory and resistors brought the rest of the truck down to 12v).
I arrived at this conclusion because my test light went supernova on me, burned my retinas and blew the bulb apart. So I would make the assumption I am getting 24v to the injector pump pink wire.
I also noticed the fuel coming out of the injector pump, and the injector pump itself was very very warm. About as warm as a pan of water that had been sitting in the sun all day.
All in all this wraps up to what do I check next? I really dont want to think of it being the injector pump, the truck only has 41,xxx miles on it, so I would hope they have a longer service life than that.
Thanks for any help on this guys.
