Question: I have a 1994 Buick La Crosse and it has
tested my every last nerve. About 7 months ago I had to replace the crankshaft
pulley, when I did that I replaced the crankshaft position sensor. 3 days later
the car mysteriously died on me and then restarted right away then died again
and wouldn't start. I was baffled as to why it did this, I then went to try and
fix the car 2 days later and it started right up, it didn't die on me until 3
weeks ago. This time it did the same thing, it died then restarted and died
again, a couple days later the car started up and ran just fine until I got
home. Ever since I got it home it only runs for about 5 minutes at most then
just shuts off. When it runs, it runs smooth and fine with no check engine
light. I know it's getting fuel, it won't run because it's not getting any
spark. I have tested all of the prongs that come out of the ignition module to
make sure that they are getting power and they all are. I have replaced the
ignition module, the ECM, ignition packs, and the camshaft senor. The security
light is not staying on so I know it's not the security system deactivating the
ignition. Somebody help before I beat this car with a hammer. Thanks, Tony
Answer: As good as that might feel......... You
might have a bad crank sensor, or damaged wiring at it. recheck that carefully
and see if it is getting trigger from it.
Question: I have an 05 La Crosse with 33,500 miles
3800 series engine, Can someone please tell me where the fuel filter is located
so that I can replace it Thanks.
Answer: The La Crosse does not have a serviceable
fuel filter. It has a strainer that is located in the tank but there is no
maintenance required for the fuel system.
Question: I have a 2005 Buick La Crosse with
32,000mi. with the 3.8l v6. Over that last few weeks, My daytime running lights
have been shutting off while I'm driving and wont turn back on and while I was
driving to work this morning in the dark, about 10 min into driving they shut
off. I tried to turn them back on manually by switching my lights from auto to
on but they won't turn back on, about 20 min later when I got to work they
decided to turn back on. Every time this happens no matter what I do I cant get
them to turn back on and I'm forced to use my high beams which don't seem to be
affected at all by this. I'm wondering if this is a computer problem. I don't
think its a fuse because they go on and off and I checked the fuses and their
all fine.
Answer: I was looking at the schematics and it
looks like the Body Control Module is what pulls the circuit to ground. There is
a headlamp module (relay) in the under hood fuse box it only controls the low
beam lights. It is relay #35 You could replace that and see if that takes care
of your problem. If that does not do it then You would need to lean towards the
BCM or a wiring issue...Is the car ot of warranty??
