I was driving my 95 rive down the road at about 60 mph and it just quit on me. The CEL came on as well as the battery and brake light. I pulled to the side and it would not start. After about 20 mins it fired right up. I got where I was going and let it sit for 2 hours then it was time to drive home. I made it 15 miles and it did the same thing. after restarting this time I only made it half a mile. this time I had to wait half an hour before it would start. Then I made it the last 5 miles home. A quick scan gave me 9 codes. I was suspecting a crank position sensor but it was not among them. The cam sensor was there though. From what I have read, excessive cranking could be the reason for that. I'm kinda lost as where to go next. Hoping someone who knows this car can help. Thanks bonk

Although there is a crank position sensor code, there isn't a crank position sensor code that will light. If you have never replaced that sensor, you might want to do it now anyway.

In a 95 Riv you primarily need to check the wiring harness at the connector to the ignition module. Some of the wires might break inside the insulation.

9 codes? what are they?
recommend you work through all of them.
they will provide insight re what has caused the engine to quit.

..................

the matter regarding how your cooling off periods allow the motor to start
suggests a failing crank sensor, but the sensor fail does not have a code.

my recall is that if the crank sensor is not bumping the engine control module,
then the fuel-pump voltage goes to zero.

Here are the codes my 9145 scanner gave me.
0561. 0565. 0640
0562. 0300
0566. 0341

I am guessing that the cruise control codes came up because I had the cruise control button in the on position. From what I have read the quad driver code is a secondary issue that usually goes away once the true problem is solved. But I am a hack amateur so I'm hoping you guys here may be able to help.

there is no magic answer for this one.
your fault is intermittent which makes diagnosis difficult.
fortunately you have clues in the form of Diagnostic Trouble Codes.

Note:
1995 is not exactly OBD-2.
Buick claims the engine control system to be OBD-1.
professionals call the '95 Riviera OBD- 1-and-a-half.
So as to get sure-fire diagnostics, when I owned a 1995 rivi we bought factory manuals and
a craigslist Vetronix Tech 2 from a failed GM dealership.

if you wish to correct this problem yourself and then maintain your '95 Riv,
your best bet is to consult the Buick factory service manuals specific for 1995 Riviera.
so, YOU MUST HAVE THE MANUALS.

the primary problems appear to be setting the 0300 & 0341 codes so
that seems good place to begin.

0300 - "random misfire"                as per manual for 1997 riv
this dtc leads to pages in the 1997 manual with a 15-step procedure to diagnose and correct.
again, you need a copy of the correct year Riv service/repair manual.

0341 - "Camshaft Position Sensor Circuit Range/Performance"  [google]
this dtc leads to pages in my 1997 manual with a 15-step procedure to diagnose and correct.
that’s 4 pages not correct for your year model, nor your engine generation, nor your OBD version,
but for your information, I have scanned them and they are below.

....................................................

Probably it is ok to put these DTC's on the “back burner”:

0561 - "system voltage unstable"  [google]
0562 - "system voltage low"          [google]

0565 - "cruise on signal malfunction"  [google]
0566 - "cruise off signal malfunction"  [google]

0640 - "intake heated air control circuit"  [google]

.....................................

summary:
get into the buick manual and follow the diagnostic steps in order.
if you choose to not get your own manuals, perhaps someone on this forum will
provide you with scans of the correct individual pages.

here are links to said 4 pages re the 1997 rivi for DTC 0341 :

Not sure if the P0341code is the same as series 2, but we have an entire thread on that code.  The main cause common to most is a broken black wire on the firewall connector.  It was difficult to diagnose but took 5 minutes to fix. See my posts in this thread,

Do yourself a favor and change the balancer and sensor. You will eventually..
