Injection Pump

[Green1]

the plan is to send it to mardy... may not be the cheapest way to go, but they certainly know Delicas...

[JMK]

I would assume that it would still need to go to a specialist shop, maybe he can get a better deal than we can at GCL. The minimum cost from GCL would be about $700.00 but probably could easily reach $1,000.00 from what I understand.

Average overhaul of this type of injection pump (Bosch) is between 800-1,300. Average cost about 900+tax.

Same with the VW's. It's the same pump. Just different injection ports and timing/a/c throttle connections.

Best bet with the Delica's is to take it to Glenn or Mardy as they would have it overhauled AND set/timing specifically for the Delica.

Green1 does pumping the primer get rid of the air between the fuel filter and the IP too? One thing that I know for sure is that the top of the fuel filter does have air in it when I leave the van off for a long duration...like 24 hours. I have loosened the primer nut on the fuel filter before and it took quite a few pumps to get diesel to come out. I don't think that is normal.

No. There will always be some little air bubbles when 1st priming however we you turn it over, the air bubbles that were sitting in the fuel line between the filter <-> IP will have passed and ignited.

Not normal.

That is a symptom that you have an air intake in your fuel system. Most likely in either the lines themselves or connecting points.

Just for the record then regarding IP rebuilds, for those in Alberta there are some options, GCL Fuel systems tell me that they have absolutely no problems doing the Delica IP, they've done dozens of JDM IP's from Toyota Land Cruisers to Isuzu's, they certainly didn't have a problem rebuilding the injectors (they did have a problem with the suggestion you could simply replace the nozzles on the injectors). I've been told by a few diesel mechanics that GCL is one of the best diesel injection specialists in Canada.

Also, for those in Kamloops, Thompson Valley Diesel Injection come very highly recommended (first by Dawson Construction, and then by Floyd at Interior Diesel), so I also gave them a call (Holley, 250-372-9300) and they said no problem for the Delica IP, I think he said they have already done a few as well.

So it looks like the options are growing for those who are either of the 'do it yourself' ilk, or don't have convenient access to the resources on the Coast.

An update to GCL. I took my vehicle there on Wednesday to have the timing done dynamically. As there was one leaking injector they also addressed that problem. Before they did the timing they checked the IP and found that the pressure was 30psi low, so they reset it. Then when they did the timing they found that it was almost spot on, quite a feat on the part of my mechanic last spring who did it by the seat of his pants without a dial guage after he put the timing belt in by talking to John Hamilton from Rocky Mountain Imports on the phone.

It appears the pressure boost on the IP made quite a difference to my power, climbing over the Scott Lake Hill easily at 100km/hr and only kicking into OD once. Fuel consumption seems to be about the same at 13l/100km. I still have some black smoke however, so I suppose my next action should be to consider doing the EGR valve modification that is noted here on the forum.

I was very happy with GCL, a very high end facility that just does diesel fuel systems, and the staff are obviously very knowledgable and also very friendly and helpful. My Delica is not the first one they've seen so they didn't have a learning curve to overcome, and they are not afraid of JDM vehicles as they've seen lots of them. The total cost for the work above was about $280.00.

JMK, thanks for the update on GCL. I think I'll be there soon.

To answer earlier questions, I got my Delica in August 2007 with 24,000 km on it. It now has 52,000, and I think the IP started leaking a little while ago. Kirkham did an oil change a couple of weeks ago, and found fuel leaking at the IP. Since then it has become hard to start. I'm hoping it is a clogged fuel filter (it now has almost 30k on it), so I'll change that first, but ...

Erebus,

When my IP started leaking my starting became difficult as well. After a complete overhaul of the IP never had a problem again and the bus is working great! So might not be your fuel filter. I think it's either that air is getting in the system where the leak is and it makes it hard to start or that by leaking there's not enough fuel readily available while cranking. Don't know if these make "mechanic" sense but just a thought.

Good luck,
David

My Delica is booked in to GCL for monday... we'll see how it goes, but at the moment starting is near impossible, I'm just hoping that I can get it to them without a tow truck!

[JMK]

Green1, how did that visit to GCL turn out?

[Green1]

I'll try to post more details next week once I've had a chance to fix what GCL did, but for the moment, I'm not overly impressed with them...

They cost me a fortune, they broke my temperature sensor, they replaced my glow plugs (at a ridiculous parts cost) but then most likely burnt the new ones out due to the broken temp sensor... they "checked" all sorts of things (and billed me for it) but the only thing they actually DID was increase the pump pressure, and I'm not convinced that actually made much difference... but it's hard to be sure until I fix the glow plug system they buggered up...
They had the van for 2 weeks, and all told it worked out to over $1000.00

[JMK]

Wow, that's not encouraging to hear. I did freak when they charged me what seemed an exorbitant amount for shipping to get one of the injector rebuild parts they needed.

Given that they had just done my pump pressure a few days before you came in, maybe that's becoming their theme song. When they first told me that in fact my timing was pretty much spot on when I brought it in anyway, I was glad they they found something they could make an improvement on. In the end the 30lbs that they boosted the pressure did seem to make a difference in my case.

I've also contributed about $800.00 to GCL in total. So given this, I'm starting to think maybe Kamloops Diesel guys may be worth a try next time then when it's time to rebuild the IP.

[Green1]

They charged me $260 for parts for 4 glow plugs, and I'm not convinced I even needed them, and I strongly suspect that the new ones are now burnt out (without the temperature sensor (which was intact when I dropped off the van, but in 2 pieces when I picked it up again) the system pretty much runs them non-stop once the engine is running)

Hi guys,

Just came across this thread when looking for potential Delica probs and was wondering where the IP is located? I'm hoping to check out a '94 Star Wagon in the next day or two and it sounds like the IP is something to check. I'll be getting it checked over properly if it looks worth buying, but want to checka few basics before shelling out $$$ on an inspection.

Cheers guys,
Dave
