Did timing belt, starts and runs, but issues...

3328 23
I have a 2014 diesel cruze with 106,000 miles. I replaced the timing belt and water pump.

When it was put back together it fired right up without a problem, sounded perfect... However, the Stabili trak and TCS needs service lit up, as well as the check engine light. The tachometer also does not work, as well as when it is put into gear it the transmission shifts very harshly and once underway the automatic transmission does not shift out of second.

Does anyone have any thoughts on what I messed up? And also how to fix it?

Also, I hooked the car up to my code reader, and got the P0016 code. As I said, it starts and runs just fine.

Jll might be right... just take of your timing cover on top and see if you can line up crank with cams and if the dots are in the right spots. the HPFP cam mark doesn't matter btw.
nope

and jesus christ nope


if the timing WAS off, he'd have grenaded the motor

his post says the engine runs fine....thats literally impossible if the timing was off

HPFP timing mark absolutely matters. The idea is to pump fuel into the common rail while it is simultaneously being injected. You want to keep the pressure in the rail relatively smooth and constant based on demand. If you have it slightly off you would have pressure drops in the rail as the pump is out of sync.

I don't know if the HPFP pulley actually cares, but it's the spacing between the fuel pump park and the cam mark that is important, which is the reason the mark is there. Would you agree? When I did my belt I made sure the fuel pump mark lined up so that the spacing on the teeth would still be correct so whether it was needed or not, it was done.

Did you pull the the wheel liner out to get access to the crank pully? It sounds like maybe you damaged or unhooked the wheel speed sensor. That may explain the first two errors. I'm not sure if that would affect shifting though.

OK, I have 2 nice days left, gonna start getting cold here in PA. Car still starts and runs, same codes. I need to know how many times its going to take to get the timing belt to match the lines on the belt again, so I can readjust this. I was cranking it by hand out there yesterday, and the lines never matched back up.

What else can I do to find tdc on cylinder 1 again, not to mention the cam? Somehow, I'm thinking that it doesn't line up on each rotation... I'm almost thinking I need to send her to the dealer and let them re-time it.

I appreciate all the help so far in my little dilemma...

I forgot the diesel is interference. Most engines that I've dealt with will run if they're 1 tooth off.
Yup - the diesel gets real unhappy real fast. :LOL:

he'd have a code for the speed sensor if that was the case.

there is no timing on a hpfp.. it just sends pressure... Just like any other fuel pump just way higher. The car uses the cam and crank to decide when to fire the injector. My belt never matched up on the hpfp.. no problems... The only problem I had was the seal leaked on the hpfp.. so If anybody is doing a timing belt I would change the hpfp shaft seal at the same time.. easy job. saves lots of time if you don't have to do the belt twice.

How do you change it?

its not too bad just use grease and a socket to make sure you press/tap the new one in straight. If I remember right it did not take too much pressure to seat it. here is my original post from a while back

I know this is long past the last post. I had the same problem where a fuel leak was caused at some time during the timing belt change. I'm wondering if it is caused when the seal on the High pressure fuel pump is inadvertently turned backwards a little while changing the timing belt... It could be worn in one direction and the backwards motion messes with it... remember this thing is under a lot of pressure and heat. anyways. Cheaper fix.. I just pulled the high pressure fuel pump and changed the shaft seal. From now on I will probably just change that seal preemptively as I hate doing the timing belt removal and install twice in a row. cheap insurance ... here is a link to the complete kit for replacing a bunch of parts in the fuel pump.

Well, this just keeps getting more and more unusual...

Decided to take the car to the dealer, so I went outside and put everything back together. Started it to move it off the ramps, and lo and behold, no lights other than the check engine. And the tach was working too. Took it out and drove it for 11 miles, got it nice and warm. no issues. The check engine light was for slow egr response.

Took it back to the house, and shut it off. Went in to get my wallet because I was going to take it to the car wash. Restarted the car, and no tach, and the other lights all came back on..

I am now stumped...

Ahh OK, so you just pulled the pump off and worked on the bench to remove the pulley? How does the seal fit? I guess it may be hard to explain without pictures.

edit
Does this look like it?
