Vito cdi112 1997 "dead diesel"

[xBx]

I got this van very cheap. It has sat four years without running. When it did last run the owner brought it to a shop to change out the injectors. The ace mechanic cross threaded one injector and then had to remove the head to repair the threads. After re-installing everything it never ran again. Typical here in the Dominican Republic. I put a hot battery in her and she rolls over fine. Even with a short shot of ether not even a pop. Im thinking timing? When i crack the injectors i get strong squirts from all four. So isn't that at least telling me the fuel system is being energized. Any help here would be greatly appreciated on what my next step should be other than the artificial reef option.

I thought all motors were 1930's American over there.

You seem to be getting fuel to the injectors, likely that is enough pressure in the fuel rail for the ECU.
You may not be getting the electric pulse at the injectors.

I'm guessing this is the OM611 engine (an early version of the OM646). That's worth confirming for others that might have ideas.

Plug in a scanner and check for faults...

M80 , you mistaken Dominican republic for Cuba....

M80 i thought the numbers on the head, of the photo i posted, might identify which engine i have? Im just getting started on this project so learning as i go. So where else would i look for engine model?
Thanks for the reply

Yeah but hes close. Mostly Jap stuff here.

Very true, I've been to both and should know better.
It's the memories of those 'Cuban' chaps racing their 1930;s flippin' big motors near Santiago. It had just rained, I could imagine the tyres being 1930's also. A bit worrying and still a strong memory.

I wasn't sure a scanner would have great purpose in an early Vito.

If you find the VIN this decoder should provide more info

I hope.
The VIN should start as WDF638

If she won’t bark on ether or easystart there is something wrong with the fundamentals - low compression or timing issues. Don’t waste time examining the fuel system until you have checked out the heavy stuff

Ive had diesel engines all my life in my commercial fishing boats. Very basic. But when you say <electric pulse at the injectors> i would assume some electric pulse being sent to the injector? (showing how little i know about these kind of things) but i see only injector lines and return lines attached to the injectors? no wires. And again just learning as i go. will not be until Wednesday to get back to the van to check on Vin#.
Thanks again for the help

Jobsworth appreciate that. Been reading up on timing procedures. I really like this van. Wouldnt have even considered taking on this project had it been a gasoline engine.

I am assuming that this is the early CDI engine. Having a common rail at high pressure, these engines then inject fuel by pulsing each injector, the timing is by pulse rather than distributor from the pump.
On the CDI each injector has an electrical feed that plugs into each injector.

Do your injectors all receive the fuel from a common fuel rail, or individual fuel lines from the pump?

 

[Jobsworth]

Looks like an om601. No electronic injectors on these, old fashioned rack pump

individual fuel lines from the pump for sure. Okay great i now understand pulse injection. But don't have that. Thanks again for your time to respond. I cant imagine anybody needing to take the injector pump off to remove the head? But for sure the timing chain. Just thinking out loud here on what could have gotten screwed-up on just taking the head off. And unless someone before me put excessive force rolling the engine over i dont hear or see any signs of the valves hitting the pistons. But not even a cough with ether? Timing right? Any common mistakes you have heard of re-timing the engine after say replacing a head gasket. off 180? I heard a German owned the shop that did this job but with Haitian mechanics so...

I would probably lift the cam cover first and check the cam timing. If that checks out, compression test next.

Been five days online reading up on timing. Thats how i came upon this site. I would also imagine four years of sitting rings could be gummed up. Might have to order a compression guage. But for now just doing what i can do with what i got. appreciate your input.

Tried easy start?

Tried easy start?

just regular starting fluid. Living in this turd world country. Nothing is easy here. All about improvising. I was thinking to take out injectors put each cylinder (at a time tdc) and inject air pressure into cylinder. I havent yet handed over the cash for the van. And dont want a major rebuild job if valves hit pistons. You think that may give me any indication of bent valves? Appreciate all the help

 

[Habil]

Not sure if it applies to your engine, but the crankcase cover breather goes hard with age and isn't available anymore

OM60X breather

 

[amazighman]

What makes u think valves hit pistons? These engines have timing chains and do galactic miles before a chain is kaput , unless someone messed with it before

 

[xBx]

the head was removed and if re-installed with the timing chain off a few degrees wouldnt that make for a bit of a problem with valve clearance?
