Riktar Posted December 1, 2004 Report Share Posted December 1, 2004 The wife had the Crank Sensor replaced back in January on her 91' GP. Today the damn thing just shut off close to home and refused to start. Thankfully I was able to coast the final 1/4 mile into the driveway. Since I wasn't here to see this thing changed I was only told that it was on the backside of the engine near the firewall. The best description I got from those who changed it were sprinkled with "colorful" words, followed by everyone leaving for vacation. Assuming it went bad again: Would it be easier to get at if I loosened the dogbones and rocked the engine forward? What else could cause the engine to simply shut off and refuse to start? I will put a shot of starting fluid through it to rule out fuel delivery problems. Quote Link to comment Share on other sites More sharing options...
Brian P Posted December 1, 2004 Report Share Posted December 1, 2004 yes, I got to it easier by tilting the engine forward and removing the Alternator (assuming 3.1L) It should come out relatively simple since it's fairly new. I have heard of aftermarket crank sensors failing quickly (ie: Borg Warner) Quote Link to comment Share on other sites More sharing options...
terryk2003 Posted December 1, 2004 Report Share Posted December 1, 2004 well, i dunno about the crank sensor...but this sounds like a symptom of a bad ignition Control Module...did you try starting it later after the car cooled off!?... :?

DaveFromColorado Posted December 2, 2004 Report Share Posted December 2, 2004 check the "DIS" fuse in the underhood fuse box, located on the passanger side of the engine bay. if that fuse is bad, then you know that your ignition module is going bad - whenever replacing the module, I always* recomend replacing all the coils, because something killed the old module, and why take chances if you don't have to. the CPS is pretty easy to get to from under the car, just lift it up, slide on your back, and get it that way, I've changed a few of them. my old Buick (2.8 V6) burned up two of them in a matter of 4 years - I won't buy cheap checker parts anymore.

Riktar Posted December 2, 2004 Author Report Share Posted December 2, 2004 Thanks for all the replies. The car hasn't started since the thing quit. I have been tied up with other problems and the car is currently sitting in the garage waiting my attention. I'll run out right now and make some of the checks you folks suggested. I will let you know how it turns out. Quote Link to comment Share on other sites More sharing options...
Riktar Posted December 3, 2004 Author Report Share Posted December 3, 2004 Shooting some starting fluid into the breather tube has no effect. All the fuses are good, yada-yada-yada. I thought maybe this thing would be under warranty since it was less than 1 year old but since the receipt is MIA that's out. I now see where all the grousing about the replacement procedure comes from. This thing is in a VERY tight spot. While I can just get my hands on it I am going to have to dig up some type of 1/4 driver/7mm(?) socket to remove the retaining bolt. I am also leery of buying from the same place again since the old part didn't last too long. Then again it's a choice of going 5 miles or 25 miles. NUTS!

Riktar Posted December 3, 2004 Author Report Share Posted December 3, 2004 Changed out the crankshaft Sensor and all is well again. Thanks for all the tips folks. They were very helpfull! Back to the original topic of this post: Could there be something causing the premature failure of the CS? This car runs like a top in every respect I can think of: Great (30+ highway) mileage, nice (For a 3.1) power, quick starts, smooth idle, etc. Is there something I should check to see if it's putting a "strain" on the CS?

DaveFromColorado Posted December 4, 2004 Report Share Posted December 4, 2004 you could've just gotten a bad CPS, that's happened to me more then once - --Dave. Quote Link to comment Share on other sites More sharing options...
Brian P Posted December 4, 2004 Report Share Posted December 4, 2004 Was the replacement that failed a borg warner? Just based on experience and experiences of my friends, a lot of their replacement sensors fail pretty quick. Quote Link to comment Share on other sites More sharing options...
Riktar Posted December 4, 2004 Author Report Share Posted December 4, 2004 I can't speak about the one that failed since noboidy remembers what the brand was but the replacement IS a Borg Warner :shock: which now has me a bit concerned. Is there a prefered brand that is best? Maybe I should just pickup another one and toss it in the glovebox for future use. Quote Link to comment Share on other sites More sharing options...
Brian P Posted December 5, 2004 Report Share Posted December 5, 2004 See what the dealer wants for one. It shouldn't be much more than the Borg Warner Quote Link to comment Share on other sites More sharing options...
GPRACER Posted December 5, 2004 Report Share Posted December 5, 2004 Definately go with a GM or A/C Delco part when it comes to sensors, much better reliability. Quote Link to comment Share on other sites More sharing options...
