1.9 alh injection pump jumped time

I have a 2001 jetta alh motor 5 speed and I rebuilt 40 thousand miles ago the car has 180,000 on it. The other night I was driving home and it started running bad would not rev and smoked I got it home and shut it off the next day it would not start so after looking it over I got to the belt and put crank to tdc and pulled valve cover to make shure the cam was still in time did not pull vac pump to tool on yet I found the the ip was 1 to 2 teeth off hole was toward the fire wall the bolts were tight so I loosen the bolts and alined holes and car started so im wondering how it moved the belt only has 40 grand on it and is not lose has anyone else had this problem im wondering if the ip is going bad or tried to lock up I would like to fined out more befor I spend 300 on another belt kit
Thanks

Was the tensioner adjusted properly when belt was installed? In CW direction? Quality parts?

Please use punctuation and paragraphs. Makes it so much easier for others to read.

For a moment I was wondering why you shut it off the next day.

Yes CW direction and yes Quality parts I was wondering if the belt stretched and the tensioner could not keep up I do drive the car a bit hard

Did you learn to use periods at the end of sentences or was it optional in your schooling? Really curious why you keep doing that.

Do us a favor and put one at the end. It's actually very easy if you are using a mobile device. Just double tap the space bar. It will automatically put a period AND capitalize the next letter. If you are not, then I presume ignorance at the rules of grammar on your part.

Possible the cam sprocket moved or IP pulley bolts? It's not stretch.
We're gonna assume it was all installed O.K. because this came on sudden like.

I would assume without any other obvious reason that this is a case of installer error. ALH timing belts do not just "jump" around on their own. Either the belt was not tensioned properly OR substandard (prothe, hans, etc.) parts were used.

I saw an ALH with the tensioner tensioned backwards run for quite a while, and some run for about 20 minutes.

Any missing teeth on the belt? Anyone know how far off the pump is if it's in the sucker hole?

Put another way... these belts don't stretch in any significant way. At least, not until the microsecond before they break.

Meaning, your issues probably lie someone other than the belt stretching two teeth... and whatever happened may happen again... this time with valves meeting pistons?!

No teeth missing. The hole was about 1/2 to 7/16 from lining up. I am going to ck the cam to see if that moved any on sat. Im thinking I'll pull the balancer to make sure there is not a problem with the crank sprocket.

Yes ran fine for 40 thousand miles.

Unless you've got the cam indexed ("locked") you're not accurate here.

Is there good tensioning on the belt? (tensioner failed?)

Tensioner issue or cam gear has spun.

Bottom line: things work, until they don't.

When I do TB jobs (like I do a ton of them- ha ha, NOT! [only have done two]) I have mirrors and a camera to get up-close shots of all my key components (it can be easy to get thrown off by "error of parallax").

I did something on my first TB that I'm not going to disclose until it's changed next (whether it goes to interval or not [now have 50k miles on it]). As it's still working I have no reason to confess! You, OP, however, since you have a problem, need to state everything that you may have had doubts about when you did all the work (those 40k miles ago).

So I checked the cam with the tool and found it did not jump time. So I took the belt off. And found a broken tensioner. Guess I need a higher quality tensioner.
Thanks everyone for there help.

If it was me, I'd order a new timing belt kit from one of the vendors on this site. It will provide you good quality replacement components for everything on the timing belt. If you got a cheap kit and the tensioner died, whats to say other components (water pump most likely) aren't gonna die next. You got lucky this time, next time maybe not.

My thoughts exactly. I plan on calling frank monday

Have you bought a lottery ticket lately?

What's the brand of that tensioner?

I'd be thinking hard about whether the tensioner was installed correctly. Doesn't matter how high-quality a part is, if it's not installed correctly it will be compromised.

I have a similar problem. After setting crank and cam to TDC my pump if off more like 1 1/2".
When I remove the timing belt can I turn the pump clockwise to align with the locking pin hole and not damaging anything? Then replace the timing belt.

If the crankshaft and camshaft are locked in place, aligning the pump should not cause an issue.
Of course, I may be wrong.

Nevada, you are not wrong. Could even turn it, gasp! backwards if necessary.

But one wonders how Steve P's pump got so far out of time. Shouldn't have moved at all if it was set up properly when installed. How about it Steve? Wuhappened?

Pretty hard for the components to move independently of each other w/o the belt loosing tension or "teeth" other than bolt(s) failed, which is usually an installation error.

The car stopped suddenly while driving. Looking at it last night, I found that the tensioner was not in the proper position. I'm thinking it allowed the pump to slip on the belt, stopping the car. Thankful that nothing else slipped. 11/2" was not an accurate measurement either.

In your later posts you say the camshaft timing was right-on compared to crankshaft, what tool did you use to check?

You are replying to a comment from 2018. Steve P did one of those bad forum etiquette of hijacking-an-old-thread-instead-of-starting-his-own-thread thing and you ended up commenting on the old stuff.

Thanks for the heads up.

Steve, as noted, start your own thread (to keep things straight): and try to use something other than "injection pump jumped time" as it's rarely the pump that's the cause of these sorts of problems [it's for sure a timing problem, but don't needlessly stigmatize IPs!]; start your own thread and it'll get figured out!
