Angry d24t coolant pressure issue

[Impolvo]

so I had a couple min to check stuff out other than the fuel lines I was checking some electrical and found no power to glow plugs on cranking

It's 70 degrees here but I figure there should be power at least at cranking

There is also an extra electric inline fuel pump pulling from the tank
It is cool nbected to a bus bar
I disconnected it and it works with direct power
If I jumper to the glow plugs with my aligator clips it instantly blows my In line fuse (30 amp )

So o am assuming there is some powering up issue

Sorry for all my possibly dumb questions but I've got much learning to do
