Question = Hi, Ive been having a problem with my
2000 Buick regal supercahrged. It has been dying
while i am driving and when it happens it usually
starts right back up. When it dies, no lights are
effected and the radio dose not cut out at all, only
the accelerator and power steering is effected.
Lately it has not been starting all the time some
times i have to wait 20 min. or longer until it turns
over. It sounds normal when i am trying to turn it
over does not bog down at all. And it also idles
Answer: First of all, with the check engine light on,
you need to get the computer codes checked. The
stored trouble codes may give an indication as to
what the problem is. You can them scanned at
most of the large parts stores for free. The dying
out problem may be a common failure of the crank
position sensor on the 3800 engine. When they
get hot, the cause the engine to stall.

Mine is a 2004 Buick Regal. I change spark plugs and wires. Now
when the car warms up it seems to have a miss in it. Someone (a
mechanic) told us it was the catalytic converter... is it possible?
What was the reason for changing the plugs and wires?
I changed the 3/6 coil because it was bad and that didn't fix the
problem so i changed the plugs and wires.
Does the engine miss at idle or any engine speed? Does it do it
more on hard acceleration? Does it seem to have no power under
Hard acceleration. Kind of pops at hard acceleration.
OK. Most misfires under accel ARE ignition related. Try spraying a
water bottle on the other coils when running to see if you can cause
it to misfire, If you are sure that the other coils are OK, then i would
suspect a plugged converter. This usually feels like a severe lack of
power, more than a misfire.
Wow you are awesome thank you very much. I will check this out.
Thank you so much.
You would need to let it cool down before it will start. Another
possibility is your Buick is loosing fuel pressure. This could be a
bad fuel pump. You may also have a bad ignition module. You
would need to check for spark at the spark plugs, fuel pressure at
the fuel rail port and fuel injector pulse signal to determine what is
missing. If one or more is not right, that will give a clue to where
the problem is.
If you have no spark but the fuel pressure and injector signal are
good, then testing of the ignition module would be needed next. If
no spark or injector pulse, then I would suspect the crank position
sensor. A high idle could be a vacuum leak. This would not cause
the car to stall or not start, so it sounds like you have a few
different problems with your Buick.
