So, I added an electric lift pump from bd and now the truck wont start . 97 12v, 270,000 miles no mods. Overflow valve? or fuel shut off solenoid?
This is not the truck in my sig Please help

 

OK, did you see if the fuel filter is filling up?

Did you crack any injector lines?

 

did not crack any lines but filter is draining

 

i can make the truck run if i hold donwn the throttle, but only for a minute then it dies did this 20 times

 

What made you add the electric lift pump?

Were there problems before this was added?

 

the ticking noise made me think the lift pump failed and i already had the electric lift pump

 

You need to back up , the mechanical lift pump in that truck is for the price & general use , the best / most reliable you can get .
Ticking can be a sign of an issue is the only way to find & fix a problem , if you want to do it right , for the least money / effort .
Then & now a fuel pressure test , 26 psi at idle , and 35 at wide open throttle , not more than a couple lbs lower than those numbers .
If pressure is low , slowly pinch the return hose , watch to see if pressure goes up , if it does then new OFV , if not , the pump may not be able to make pressure .

 

More than likely your electric pump isn't putting out enough pressure.
Replace with a mechanical pump from Cummins, about $70.

 

but why would this happen only after i added the electric pump? even if the electric pump isn't putting out enough pressure it would still be more than it had before and the truck ran fine before that.

 

I thing you missed the point , the old [ no fuel pressure test ] just ticking may have been making good pressure .
Then you put in an other pump [ stlll no pressure test ] , now you have a new problem , odds are , the change in performance is from the change you made with out testing before or after .
The ticking would have been a good reason to test the old pump , now you have a reason to test the new pump .
Testing saves more money than parts .
