Intermittently my 1997 Buick LeSabre 55k miles will not start after short trips. Runs and starts fine cold but when turned off after around a 5 mile drive and sits for about 30 minutes it turns over but will not fire. No check engine light, no trouble codes. Let it sit for another hour and it starts fine. Runs and starts fine after longer trips. Any ideas? Thanks
Do you own a scan tool ? One that shows engine sensor data parameters ? Checking sensor data would be the thing to do .
047 Engine Hard to Start or No Start Scan Data for Ignition
Check spec. to factory spec.
048 Engine Hard to Start or No Start Scan Data for Starting Problems .
SOURCE: 1995 Buick LeSabre - horn blows
My horn would honk without any assistance from me. The
reason was because the plastic cover for the air bag and horn switches had
shrunk so tight that it pressed on the horn switches. If your problem is
intermittent then cold temperature would also cause the cover to shrink. This
is how I solved the problem on my 1995 Buick LeSabre:
Disconnect the negative battery cable.
2. 2.
There are two plastic twist locks (turn ¼ left) and one small wing nut holding
the cover on. When the cover is off I see two black fuse covers side by side
and below them are several relays. Some are gray and some are black.
3. My
horn relay was the second from the left as I faced the rear of my car. It was
gray. Some may be black.
4. A
small green retainer tab had to be pushed out before I could pull the relay
out. On the back of the relay were two orange wires that supply 12V. One green
wire that goes to the horns and one black wire for ground that goes to the horn
switch under the air bag.
5. I
cut the black wire and wired in a spst push button switch that I connected to
ground.
6. I
mounted the push button switch near the driver’s door on a flat part of the
dash. I used very strong double sided tape to secure the button switch to the
dash.
My horns now are activated when I
push my new horn switch button. My problem solved.
Someone recommended removing the
air bag/horn switch unit from the steering wheel and relieving the tightness of
the plastic cover. There are probably more than one way to this.
SOURCE: 2001 Buick Regal cuts off while driving at times also won't start
The ignition switch on that model is rated @ 50amps. When I was driving my 2001 Regal LS (at 120,000 miles) and used the turn signal, the engine would die, when I switched the turn signal off, the engine ran. So I replaced the ignition switch, and all is well.

SOURCE: AC/heater fan on 1992 Buick LeSabre only works intermittently
Could be a bad control switch, relay or connection and ground at motor itself. Since it's intermittent, check voltages when it's working, then again when it's not. Wherever voltage stops, that's what you need to replace. Don't wait on this...when completely inoperative it gets much harder to find the problem!

There are a couple of factors here:
Hope this answers your question and gives you a good place to start. All the best.

SOURCE: ABS & Brake warning lights turn on
it is possible but its also possible you have a wheel speed sensor acting up. you would have to have it scanned for codes
Its
a hot start issue.
Can
be related to low fuel pressure or problem with crank sensor.
Also
it can be weak battery or starter.
But
possibilities are to be inspected to confirm what exactly it is.------
