A very long story made short...I bought a car that had taken water in and bent a connecting rod on auction.

The engine has been swapped with one that was running prior to removal, the original DDE has been tuned by JR Auto, and water injection has been installed.

The car cranks but will not start at all. All accessories work and while there are a couple minor codes, there are no fault codes that point to why the engine won't start. The ECUs are all original to the car and are working together, ISNs match etc so it's not that. The injectors are properly coded (original to the car, not the engine and are in the same positions).

Can anyone think of a place I should start? I'm going to try to bleed the fuel lines tonight but am unsure of what else I can check.

Id be willing to bet its that the hpfp wont prime... take a look at my hpfp post, there is a procedure on using INPA to prime it

Thank you! I'm sorry, I'm not quite sure how to search for it or do I just browse your posts?

Okay I used Rheingold to prime the pump for 3 minutes but no change :/

Hmm...well make sure you are getting fuel TO the hpfp I guess by unhooking the hose and letting it run out into a bucket....

Other than that..its gotta be priming that hpfp...

Might be covered already, but was the DDE recently reconnected. If so, try re-seating the connections on the DDE as it is an item you mention and can cause a no start.

Thanks, yes I did try reseating them twice with the battery disconnected and no change. When I run Rheingold it connects to modules fine, so I'm assuming based on that also that there isn't a communication issue

SUCCESS!

Ran the bleeding function in Rheingold twice with no change, took off one of the lines that run from the rail to the injectors and no fuel leaked out. So...no fuel getting to the injectors.

We manually pumped some diesel into the rail until it wouldn't take anymore and the car started up after about ten seconds!

Not sure if it was the adding of fuel that got the pump working (primed) or just the fact that we cranked it over enough times, but whatever it was worked and the car runs. Thanks for the help!!

^ good to hear. If the rail is dry it takes a bit to get her going, even with priming the system.

So how did you manually pump diesel into the rail? Can you be a bit more specific on how you did it?

Yeah, if the fuel rail was completely empty it's gonna take awhile before you build up enough pressure to get it to fire off. You probably would have gotten it eventually if you continued priming. Either way, glad you got it done.
