#25 of 89 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???

#27 of 89 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.
#30 of 89 suddenly wont start by sclipson Mar 10, 2008 (3:54 am)
it does sound like the starter. any good shop can verify this quite easily.   reset the change oil light. the manual will guide you as to how to do this.   good luck
#31 of 89 Siren type noise from engine on acceleration by trini3 Apr 01, 2008 (5:19 am)
Hi Folks, I have a 2001 aurora with the 3.5 V6 engine. I recently discovered a siren type noise that increases and decreases with acceleration or deceleration. It only starts when I' up around 60mph. I guess it appears to ha a vacuum leak like symptom. Help if any one has ever had this problem. Thanks Replies to this message: racuatt (Nov 14, 2008 4:53 pm)

#34 of 89 2001 Aurora by hannig43 Apr 03, 2008 (9:42 am)
I've read all of these accounts and it sounds like my CRANKSHAFT SENOR(s) need to be replaced too (it stalls at wierd times)....also the tach is shooting up to 8000 even though the engine isn't reving that high. Does this sound familiar to anybody? Are they related?
