Iv got a 91 non turbo that will not start at all unless pull started need help asap I know starting fluid is bad but even after a good shot after the glow plugs cycle won't sputter or nothing. But if you pull it, it fires right up

 

first check bateries, then its usualy glow plugs, but it can be the controller or the temp sender in back of block ther is also a cylinoid on manifold that sends power to glow plugs check to se if your geting power to glow plugs when light comes on. i like to pull glow plugs and test with a batery. 6.9s are notoriouse for bad glow plugs if they dont work no start.and dont use either!

 

starter could also be bad. not spinning the motor over fast enough.

 

It's spinning fast enough I know that. I have 2 1989s 2 1994s a 1993 and a 1996 all ford diesel except for my dodge. I just noticed some diesel leaking out of the return lines overnight would that do it? Thanks

 

yes that would. any fuel leak, either feed or return will cause they system to bleed down. get a fuel line return kit, sold online for about 30 bucks. replace the orings, caps, and lines.

 

Ill do it tonight an let you know how it goes.

 

i just replaced my return lines and got a leak on pass side rear injector leaks out of where the fuel line goes into the nut that screws onto the injector any suggestions?

 

did you cross thread it?
is the end of the injector fubar? or the end of the line?

 

is it fubar? whats that?

 

f-ed up beyond all recognition- fubar.
