well i just recently changed the fuel filter on my 1.6TD and well for the time up until now its been fine. But going to start it this morning i got nothing, it would crank over but not fire up. I had the same problem yesterday but it did eventually fire up, and then driving around was fine, i could turn it off, go to a store come back and it would fire up no problem. Just wondering if it could have something to do with the new fuel filter?
thanks for any input you might have.

If you are missing the top o-ring, it sucks air.
-
well i got it started again, took forever. O-ring you say, ill go check if its still there. Should just be a little rubber ring that i could pull off?
nope o-ring still there. There's a sucking noise when i take the cap off. couldn't be to do with the glow plugs could it? i mean when the car starts up its normal plus i turned it off for a minute and it fired up right away, its just when its been sitting over night or for a while. But its never done this until now and i dont know what would have changed. :?:
-
so my mechanic friend says that i might be burning coolant, and that my head gasket is leaking because when my car fired up a lot of white smoke came out, plus that could expalin why it took so long to start because it wasnt getting the compression it needed. So now either i can get the repair done ( a nice chunk of money that i dont have) or i can sell it. Now of course i know i couldn't get a lot with this type of problem but i would be willing to sell it to one of you diesel heads nearby in hopes that you can fix it and be able to continue to use its services.

It sure sounds like a burnt glow plug fuse to me. A lot of fuel=white smoke.
Check the fuse my son....don't focus too hard on the filter.
-
as in fuse down by the advanced timing choke?
any idea which fuse that might be?
-
It depends on what you have. Most are on the firewall with 2 large red wires to it. It's a flat metal strip with a screw on each end.
-
got a location? i have a 1.6l turbo diesel in a 1991 jetta.
-
On the firewall (small lack case)with 2 large red wires to it
-
hehe, which side of the firewall, engine bay or cabin? and if in cabin, behind the fuse box?
***!!!! THe fuse is broken!!!!!!!!!!!!!!
You just made me very happy!!!, what can i use to replace it? not some special VW fuse is it?
-
:oops: Engine side :oops:
-
FOUND IT.. Its broken! :shock: thank you for your help, hope its the problem.
-
Let me know how it turns out.
-
IT WORKS!!!!!! you have no idea how ***ING happy i am thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you!!!!!
-
now the question is, what do i use to replace the fuse?
-
The last ones I bought at the dealer were about $.50 each but I have replaced it with a piece of wire to get me there....always buy 2 and keep 1 in the ashtray.
See the problem when you replace a part and then focus on that part???
Always look for the obvious first.
Glad to be able to help.
-
you have no idea how happy you made me! see thats what this forum is for, cause you diesel brains know what to check for first. My mechanic buddy, i guess from working on gassers so much assumed white smoke to be burning coolant. once again thank you so very much! haha, cancel the selling of my car :lol:
-
Yeah, that one burned be before as well. Also, if you're driving along and it goes dead, you can also look at the connector on the injector. Mine had a habit of backing itself off just enough (combined with the amount of oil on the engine) that it would exhibit similar problems.
Leave it overnight. If it behaves the same after checking those two things, it may be your fuel filter hasn't filled up with fuel and the injector is sucking air. Last time I replaced mine, I didn't put any diesel in it, but I believe that the best practice is to do so.
You'll make 'er.

:D :D

the proper replacements are cheap, I got like 4 for a buck and still got some change back

,,yea get the right fuse,,,,ihave fount they usually dont "blow",,they rot apart,,usually where one of the screws holds it down,and its not really visible tillyou remove it,then it falls todust in your hand,,,,in a pinch,,ive taken like 3 strands of wire,and twisted them together,for a temporary fuse to get me out of the boonies :wink:
-
are they specific fuses or can i get them at walmart of canadian tire?
-
I'm pretty sure they are specific. Because the glow system can draw a lot of power for a short period of time its probably best to grab the best fuse money can buy (or a few cheaper ones... especially in winter)
-
no one would happen to know the amp rating would they?
-
They are only available from the dealer, or a VW parts place because of the mounting. They are 50 amps, I believe.

Moved to troubleshooting
It was already IN troubleshooting. :oops:

thats what i thought :?

I'm glad that you guys agree this thread belongs in troubleshooting. IIRC before I moved it, it was miscategorized in the IDI Engine (power enhancement) section, but I could be remembering that wrong. :oops:

Aha, the heady aroma of diesel soot has finally effected your brain cells :wink:

I just bought a couple of them today from the stealer. I didn't know if regular parts places carry that type and they were only a couple of bucks a piece. Part # is: N-017-125-1 50 amp fuse
Not to hijack this thread, but I had a similar problem today:
While trying to figure out why my Jetta wouldn't start this morning I figured glow plugs and started looking for the fuse. Bently wasn't much help and I found some web sites that mentioned that it was located near the strut tower. I looked and sure enough there was one of them fuses right by the strut tower and it was corroded to the point that it was in pieces. I stuck a piece of wire inbetween just to make sure there wasn't something else wrong and it didn't do a thing. So then I was thinking relay and while searching for the relay I found the little black box on the firewall with the glow plug fuse. That was corroded to the point of there being nothing left as well. I stuck a wire in there and viola!!! Car started perfect.
I later found out that the first fuse I was looking at was for the fan controller. After replacing both fuses with real ones I sprayed them with some of that battery terminal greasy paint stuff to hopefully keep them from corroding away again.
Question for the gurus: After cranking for quite a while this morning due to no start I hooked up a remote starter switch to get power directly to the gp bus bar and it fired right up afterwards, but it made a hideous sounding racket for like a 1/4 - 1/2 second that sounded like valves hitting. Is it possible to essentially hydrolock a motor by cranking it for a while and not having it fire? Was that noise indicative of something bad? It's been running fine since, but that noise did not sound good at all.

Doubtfull, what usually happens is the cylinders get loaded up with a large quantity of fuel. When the engine finally fires all that fuel combusts at once and produces some fairly loud diesel clacking for the first few strokes accompanied by a glorious cloud of black smoke. I wouldn't worry about it.

glorious cloud of black smoke... brilliant!

Two choices:
1) go to the dealer and get another fusable link (get two and put the spare in the glovebox with a screwdriver)
2) Get a 50 amp circuit breaker and never change it again. Any place that sells truck parts should have them on the shelf, two terminals sticking up to hook to. Just make sure you get one that has ears to mount it with, some of them snap into place instead of bolting down.
