Is the timing of the injection pump on humvee different then a CUCV?

HI All
Thanks for the replies earlier this week, I got the ground strap
("short") problem sorted out, she spins over really good with no
"smoking". But I still have a fuel delivery problem. The glowplugs don't
work so I use either to start it (in very small amounts), this is ok as
long as the glow plugs don't activate, and you don't get carried away,
been doing it for almost a year.
After bleeding the injectors several times, but it still wouldn't start,
I decided to give her a compression test this morning. I have between
400-420 LBS on all 8 cylinders, well within the boundries of acceptable
compression, that's the good news. So while I have the glow plugs out, I
cracked all 8 injectors open, with the throttle pedal floored I spun the
engine over twice at about 12-13 revolutions each time. The area around
the injectors was wet on all 8, so I closed all the injectors,
re-installed the glowplugs, gave her a shot of either, and cranked her
over. She rattled a little then seemed to catch for about a second and a
half, then died. I then gave her another shot of either, and cranked her
over but she only ran on the either.
I don't think I'm getting enough fuel to the injectors, OR, the
injectors aren't getting enough fuel to the cylinders, but since it
almost started, I'm thinking the injectors are ok, and maybe the
injector pump isn't putting out enough pressure, just guessing though,
as I have no way to test that. I replaced that pressure switch this week
that's in the fuel filter housing, and have a new fuel filter. When I
initially cranked her over with the fuel filter removed, she shot fuel
from the housing all the way to the radiator, so I'm pretty sure I got
plenty of fuel flow/pressure to the injector pump.
I bought the engine from Ted's Trucks and Stuff, as a HUMMV take out,
they tested it on a stand so it should run.... I had to change out the
HUMMV for the CUCV attachments on the injector pump, but everything
seems to work ok. The fuel shut off solenoid works. So I'm at a loss
here as far as to what the next step is to take, so any advise/help is
appreciated.
Thanks - Tom
