For what its worth, check the connection at the fuel quantity control valve .
You may have molested , whacked it or indeed damaged the valve during your repair doings.

I bet you bumped one of the quick connectors on the clear fuel lines.

Also if your battery only has 12v it is weak. 12.06 volts equals only a 50% charge which is not enough to fire the injectors. You should see 12.7 volts when fully charged.

Check the writeup section. A belt alone can be removed simply by detentioning the tensioner with a wrench and then slipping the belt off and up out of the top of the engine bay. If doing pulleys, then you just remove the grille and radiator cross member which is just a few screws and bolts and then ease the whole coolant pack (radiator, intercooler, AC condenser, power steering cooler, aux fan) forward to gain access to the pulley bolts.
No worries, thanks!

Yeah, Iím kind of realizing that now. I think the tensioner would have been tough to swap out..I know you can do it from below though.

Thanks for the info on the battery. I canít remember what it is at exactly, but Iíll check tomorrow as well.

On the front of the HPOP just where the serp belt runs.

Worth checking. Definitely reassemble everything.

I know that when there are air leaks in the hose from the air filter box to the turbo it can cause odd symptoms. I recall that including no start, but I don't remember whether that was from T1N or NCV3 comments. With nothing connected it could affect starting.

I see from your profile your van is a 2006 3500, so your OM-647 engine doesnít have the clear fuel lines or quick connects of the OM-612... instead youíve got an in-tank fuel pump that pushes fuel through the fuel filter and into the HPFP at around 80 psi. Failure of the tank pump can cause a no-start, but that is very unlikely to be your current issue.

Have a good look around for collateral damage. As Dennis alluded, there are many wires and hoses in the path of the belt when it came loose. (some electrical faults will be noticed by the ECM and generate a fault code. Youíll need to Sprinter-aware scanner to read them, though a generic OBDII tool may offer some guidance?)

If you swap the HPFP quantity valve connector with the PCV heater connector, the engine will get a code, and possibly stall after 30 seconds. The connectors are the same type and are long enough to interchange.

Default Re: Not starting after changing pulleys and tensioner ?!

Wanted to chime in since I made this post. It’s been a ride lmao.

I re-assembled the whole front end. Went to start it and couldn’t find my key...the only key I had!! Ugh.

Ended up sending requirements parts into SOS diagnostics so they could make me keys (after wasting a few days calling local people that wanted to charge an arm and a leg).

Got the keys in and ta-da!! It started.

Lesson learned: car won’t start without radiator.

NEW QUESTION - check engine light is on now, ugh! Any ideas why this could happen after changing the parts I did?

Thanks everyone!

Your best bet is to plug in a scanner and see what code comes up. It may be something as simple as the ambient air temp sensor being unplugged
