Replying to: sclipson (Jan 23, 2008 10:46 am) Hi ther I can relate to your frustration concerning this. Mechanic replaced the lower crankshaft sensor, brought the car home and 10 minutes later it did it again. Took it back and they replaced the top sensor (harder of the 2). car ran great for 2 weeks then started again. went back to mechanic, they replaced the ignition wires. 3 hours later did it again. went back and freaked out on dealership. they kept the car for 1 week, it too did not have a service engine light on, no codes and they were totally baffled about it. they contacted Gm and after basically going thru the whole car, decided to replace the crankshaft sensors again and clean the contacts when they connected to. this was 1 month ago and the car seems to be running fine and has not acted up since. hopefully this is the end of the stalling issue. it to was stalling at stop signs and traffic lights and would always start right back up. as per several mechanics I have talked to and many searches on the Olds Aurora Website, if you replace the crankshaft sensors, replace them both at the same time and make sure the contact area are clean. hope this helps and good luck

thanks for your advise on the sensors. i showed your response to the dealer , and they said if the sensors were acting up, it would leave a trail, i.e. codes.   obviously none of us really knows the answer. went ahead and ordered new sensors anyway, as it was'nt that much money. if this doesent work, it goes on the block.

Replying to: sclipson (Jan 24, 2008 4:50 am) Please let me know if the new sensors solve the problem. If so I will try it. I have the same problem (engine dies just like I turned the ignition key to off) and have been shifting into neutral at every stop light. My problem started after I installed new plugs and wires and I have been trying to decide if that is the problem. Did your problem start after installing new plugs and wires?.

sorry to hear you are having the same problem. no, my problem did not start after having new wires etc. installed. car had been running great untill about a year ago. does not do it very often, but enough that my wife will not take it more than a couple blocks from home. one thought was that the egr valve was acting up but that checks out all right. hopefully the sensors will arrive shortly and can get them installed early next week. its been one fine automobile and my wife does not want to give it up, but will in a heartbeat if this problem isn't fixed soon. i'll post my results as soon as i can .
#25 of 83 95 Aurora hard starting and hesitation under load by dkocchi Feb 21, 2008 (8:13 pm)
I recently had my 95 into the dealer for a 3rd replacement of the AC comp. All is fine with the AC now, but a couple days after I got the car back form the dealer, after the car sitting for the afternoon it would barely start, but started, and was drivable but running very poorly. The next morning the car would not start. We had the car towed to our mechanic and he determined it was the fuel pump ($650), the pressures were low 12psi, and I guess were SB about 40 something. All made sense at that point. I picked up the car and all seemed fine but the car was still hesitating, when you decellerate and then gradually accellerate, the car would hesitate and backfire. (This hesitation was present even before the AC problem, I was hoping the new fuel pump would take care of this problem.) No such luck. The car still had the same issues so I took it back to the mechanic. The car would now stumble when trying to start, but start and also continued to hesitate as described above.(periodically) The mechanic could not figure out what was going on, the pressures were fine on the new pump, but felt it might be bleeding out after sitting for awhile. He continued to replace the fuel pressure switch. The problem is still not fixed. He tested plug wires, coils etc... with no problems found. The conclusion, it may be a defective fuel pump. He offered to changed out the pump for a new one. I guess we will see if that takes care of it, I have my doubts. Any other ideas???

after my previous post on engine stalling at a light etc., i had the crankshaft and cam sensors changed and all now seems okay. have not had a problem and have added approx one thousand miles since. hope this continues, as we are taking a trip to fla soon. will report back as to how that goes.
#27 of 83 My 95 Aurora Suddenly Won't Start by ndeysayau95 Mar 07, 2008 (5:32 pm)
I am new to the site, I recently bought a 95 Aurora. When I got it I had to replace the thermostat & water pump due to overheating (it was welded into the housing unit wow!) I did this myself (mind u I am a woman hahaha). After fixing this problem the car ran well! Then one day I went to start it and it was hesitant, I had to turn the key a few times before it would start. The next morning I went to start it and it did nothing, all I hear is a clicking under the backseat. Had the battery tested it was goo but low so they charged it. Still nothing. I should also mention that some extra things were attached to the car (backup battery for an amp in the trunk) the day before the car wouldn't start wires touched & arched. Also my "Change Oil NOW" light on the DIC appeared about 3 days after the oil & filter were changed. Possible oil sending unit prob? If so how hard is it to replace? PLEASE help! Sorry for such long msg just trying to be clear. Thanks in advance!! Replies to this message: spur2 (Mar 08, 2008 8:03 am) ndeysayau95 (Mar 08, 2008 1:27 pm) skurz374 (Jun 02, 2008 5:58 am)

Replying to: ndeysayau95 (Mar 07, 2008 5:32 pm) As to the "Change Oil Now" light, it probably needs to be "reset." Push the reset button on the DIC. As to the failure to start problem, I have not experienced that with my 98 Aurora but it sounds like it may be the starter. I understand that 95 Auroras have had some problems with fuel leaks and possible fires. Do you know if yours has been repaired for this? Replies to this message: ndeysayau95 (Mar 08, 2008 1:27 pm)

Replying to: spur2 (Mar 08, 2008 8:03 am) Thank you for the input. I am not sure if mine has been repaired for the fuel leaks. I did read in some of the other posts about one of the lines being recalled. Im hoping that it is not my starter as this is a costly job. Maybe it's my fuel pump considering I ran out of gas in the car twice, and then filled up. Once again thank you.
