Finally did the timing belt on my 2002 XG350 now that it just turned 90,000
miles. After about 8 hours of hidden bolts, no access space, and bleeding
knuckles it was finished. Started right up, ran it around the
block...running good. Next morning I drive to work. 50 miles. No
problems, cars running great. At lunch I hop in the car, and the car
doesn't start. No spark
Can anything come up with a scenario that would fit this? I'm having
trouble. Only thing I can think of is maybe the crank sensor by the water
pump that got a little wet when the water pump was replaced? Does such a
device have a startup circuit and a run circuit such that the startup
circuit could go bad while driving to work and it only gets noticed the next
time I try and start the car? I know its not the timing, as we marked the
belt, transferred the marks to the new belt, then installed the new belt
(this worked very well by the way) and then checked the timing marks too,
and everything was dead on...plus it drove 50 miles running perfectly.
As always, your help is appreciated
If it's related to anything you did, I'd primarily suspect that the crank
sensor wiring may have gotten caught up in something. Can't hurt to check
all the connectors you had to pop loose to get to everything.
If it cranks faster than normal, that's a sign the timing belt jumped for
Sorry about your trouble, Dan. And, no, I don't have any answers for you.
But I do have a question.
I am trying to ascertain how long that 3.5L engine can REALLY go between
timing belts. I know one should not really play this game, especially with
an interference engine.
It seems that some engines, where replacement is called for at 60,000 miles,
will go well over 100,000, while others seem lucky to get to 50,000. I'm
wondering what this engine will do.
What condition was the belt you just took off?? Just curious.
As far as I was concerned, the belt looked fine. But the guy doing the work
(a friend of mine) said that it looked like it needed replacing. Some of
what he based his opinion on was the fact that the nice bright white
lettering on the back side of the belt was faded down to be almost
unreadable and he said that someone else once told him that that was one of
the "tricks" you could use to help decide if the belt was good or not. I
suspect that the belts are just like modern radiator hoses these days...you
really can't tell by inspection. At any rate, I used 5yrs/60000 miles
whichever comes LAST and got away with it. My wife's XG350 (yes, we have
his and hers) is 5 years 60,000 now and I'm planning on doing that one
within the next month. For what its worth, HyundaiTech said that the XG350
is "not known for throwing its belt".
The problem with mine, by the way, was the crankshaft position sensor wire,
the insulation had broken down and it had shorted. We found out that the
crankshaft position sensor is only used to start the car and then the
camshaft position sensor takes over, so that explains what happened to me.
