My 93 cummings turbo won't start w/o ether wether it is cold or hot. Not even if I give her a little pedal or alotta pedal. I changed the transfer pump but no luck. Does anybody have any good ideas? I am guessing it is probably the injector pump but don't want to be wrong.
THANKS for any help

 

A few ideas, check the shut off solinoid wires and make sure your getting voltage to it, these solinoids go bad and it wont start. are you getting fuel ? try pumping the pump lever after you loosen the line going to the injector pump ,see if fuel comes out, may be as simple as a cracked rubber hose. some other will chime in with more ideas, but dont go buying stuff you dont need, these little checks are free.

 

If it starts with eather then I'm not convinced that it is the shut off solenoid. I'm leaning towards the cracked fuel lines. check the fuel lines from and to the lift pump and see if you are sucking air. hope this helps, and welcome to dtr.

Loosen every other injector, just a hair, be careful of the fuel spray. Get a partner to turn the key and tighten the injectors back up while it's cranking. It my fire right up while you do this, if it does it'll run ruff. After those three are tight, crack open and retighten the other three, one at a time. The idle should smooth right out as you get these done. You might have air in the line from changing the lift pump and haveing a previously bad lift pump and this should help. If it fires right up and gives you problems again later, you may have bad fuel lines to the tank, that allow it to lose prime when it sits.

 

I think you're getting air in the lines like timb says.

 

like wanna has always told me. put a shop rag in the filler in the tank then put your air hose in there and fill it up! this will force any fuel out of the lines, when there is a leak not all of the time fuel will come out when you are trying to start it.

I learned that trick from Pastor Bob.

 

if you put air in that tank make sure you dont build to much psi wen i do it i put my regulator to 5 psi thats around the psis the system makesmaybe it does not matter but i better be safe then sorry

 

thanks for all the ideas i'm on my way to the garage to check it out right now
