WOnt turn over after changing out glow plugs

[tamra070]

Hey Guys,
I have a Delica Chamonix 1999 turbo diesel. I would have to turn the glow plugs 3x or more to get my van to start and when it started it sounded pretty rough. I had my boyfriend change the glow plugs to new good ones (not aftermarket). I drove it home then the next morning the Van wouldn't start. I had to hold the key multiple times for it to finally engage. He also said he could hear a slight knocking sound on cold start as well there is a small rattling sound under the dash on the driver side. Do I have faulty glow plugs because now I am worse off than I was before. Sometimes I turn the key for a really long time and it still wont engage. It doesn't even sound like it is trying to engage. Could it be pistons could it be the glow plug bar where the electrical is hooked up to the bar not the first spark plug ? When it does start it initially sounds like it is running really bad and smoke comes out the back.


Any help is greatly appreciated

Sounds like a problem with your electrical wiring or your starter.

Even if you take the glowplugs out you can turn the engine over. It won't do anything, but it will turn over.

Best guess, there is a bad contact somewhere.

Not after market but are they the correct glow plugs? The Electronic Control Unit (ECU) operates based on resistance measured from the glow plugs. If you put 4D56T engine GPs into a 4M40 engine the resistance will be wrong.

When you say the engine is not turning over ~ do you mean that it's not starting or that the starter is not turning over the engine? I think Mister Flibble might have a point, the first thing I would do is take a wire brush and clean your battery terminals and cable ends put it back together, get a boost and see how she starts. I'm guessing if she doesn't start properly then perhaps it's the glow system. If she does start then go for a drive down the highway to recharge your battery. If the former is the issue then I'm thinking either the GPs are at fault, either faulty or mismatched or something is at fault with the ECU, such as a blown capacitor.

First thing I'd do is clean the terminals & cable ends. It's far cheaper and less involved. You can get a wire brush especially designed for terminals at any auto supply store.

Next, if that doesn't work, check the glow plugs OEM parts number. There are at least two models of glow plugs used for the Space Gear. I would recommend going to the Delica FAQ Section (see the board index); look for "Useful Links for Vehicle Part Identification Purposes." Scroll down to "JDM Online Catalogue", click on that; enter your vehicle's frame number into the Mitsubishi field, it'll look something like "PD8W-XXXXXXX" (seven numbers), click enter and you should have your vehicle's stock history in front of you. Scroll down to engine electrical (I think it's section 16), click on that and look for the sub heading "Glow Plug & Relay". Click on "Glow Plug", it will give you a PNC# and an OEM#. You want the OEM number. Compare that number with the number of the GPs you installed and see if they match.

If they match and you've ensured all the connexions are cleanly connected and you're still having trouble starting then look to the ECU and relays. There are a number of ECU models out there so you have to pay attention to this detail. there's a write-up in a thread called Regarding the ECU. that will give you an idea of what you're up against.

There is another parts link in the Useful Links for Vehicle Part Identification Purposes thread called "partsbase.org/mitsubishi/jp/" that has exploded views of the parts you want but I would correlate those numbers with the ones in the JDM Online Catalogue, to be sure.

Hope this helps.

Falco.

The temperature has been cold so I bought two 600cca batteries and replaced to see if that was the problem. I cut a couple inches off the wire to the bus bar incase their was corrosion. The bus bar has 12 v. Now my van will not turn over unless I get a boost from my boyfriends cummins diesel truck.

At this point new glow plugs, power to bus bar, new batteries. Only will start when I get a boost then runs fine for the rest of the day. I have the 1999 delica Chamonix turbo diesel and it is fitted with a valve that you can push in out or that says throttle. Would it help if I tried to pull it out on cold start? I also have a valve that you can push in or out on the left side that has a weird symbol. Not sure what it is but you can push it in or pull it out as well. It is only on cold start vans as I have read on here and some say it has to do with an air intake flap. Is there something I should be doing with this valve on cold starts ?

The fact that the unit starts when you boost it with another vehicle tell me that the Delica's electrical system is fine.

first: Recheck your battery connections and be sure they are all CLEAN and TIGHT...check for broken battery clamps, loose cables
second: Get a charging system test performed. This will test the batteries and your alternator's output. PartSource does this for free in the parking lot...so does Canadian Tire.

I have seen new batteries fail due to an internal short so it can't give you the amperage needed to start a cold engine....once the engine is warm, and the outside temps rise there is less demand on the batteries and the engine will start.

I experienced a similar only cranking when connected to an external power source (booster/car). It turned out to be the ground wire. Trace it from block to body to battery 'Y'. Hope it works for ya

Hey, what are you doing back on here?

Threadjack I still need to find out exactly which outfit you used in North Bend Washington to get that Montero Locker....
