with key off just use a jump button on the b and s terminal of the starter, then you can stay in the front of the truck, if fuel is pumping to the lines and you know you put good injectors on the front it has to be a problem with the piston, or the rings, is it leaking oil from a rear main seal

 

I saw that truck on craigslist and wanted it....
Hope you get it running good

 

Isn't there a minimum amount of pressure needed to pop the injector? I don't think it is leaking out the rear main. If so, not much.

 

it needs to be 260 bar
