Bleeding td42 after injector rail replacement
Hey guys i just changed the injector spill rail on my 93 td42 maverick i bleed the injector pump and have fuel coming out of the injector rails when i try to start it but no luck it just keeps turning over sometimes might fire on a few cylinders but no good would anyone have some suggestions on what i might try to do?

Are you sure your priming pump is working ok , bled the screw on top of the pump properly ? Sounds like there's still air in there somewhere .

Pretty sure i have, should that be the only way you should need to bleed the injectors, there would have been a heap of air in the fuel rail when i changed it

Nah I think you have to crack each line , one by one it just depends on what's happened ie run out of fuel , done what you did etc .
I've only had to bleed once when I worked on the injector pump but gave it a good prime until I was happy with it , then after starting I ran around to the prime pump and pumped the bejesus out of it in case it stopped .
If your pumps primed and your injectors are primed it should go .
Have you tried getting someone to crank it over while you hand prime .

It has a massive weird ass hand primer pump on it to looks like something off a 1950s massey Ferguson lol definitely needs to be changed out for a better pne but i cant see this being a issue

Should be a circular black plate type thing on the fuel filter that you push down repeatedly , might have been modified , I thought the old masseys had a tiny handle type piston pump .

Yeah they do lol was just referencing an old diesel tractor and the massey sprang to mind although atm the massey is more reliable than the maverick lol, its a weird setup has a long pipe coming off the top of it pointing towards the motor with a handle you unwind at the end then you pull it out and push it back in closet thing i can think its like is a push bike pump if you know what i mean
