1999 SL2
I have a four door 1999 Saturn SL2 Automatic that just recently started
having electrical issues. About two months ago was driving in extreme heat, shut off to fill with gas, and would not restart. After sitting in shade for about an hour (jump did no good battery fine) it restarted and made it home and then died again. Helpful mechanic diagnosed it with testing meter to be Relay switch--and we replaced the main one and the one that controlls the AC to be safe (and even bought two spare just in case). Ran great for about a month. Then another scorcher....died....remote keys/alarm would not work/radio would not work/car would not start/ headlights work/interior light works/dash lights come on when try to start.....no fix when change out relay switches.....Let car sit for 2-3 hours....started and ran fine for 1-2 weeks (but radio/clock all reset) Happened again today...very hot and humid...all above symptoms...towed home....called mechanic and described...he wants me to research too as he's stumped. Luckily home and so is car...and can borrow if can...research seeming to say to start with Crank Position Sensor? Does this sound posible? I'm sure it will be tough to test as by the time he can look at it, it will probably start again...and I do not have much knowledge or meters...I just need advice to help point him and not empty my bank. Any/all help will be GREATLY appreciated!!! Thanks |

Please describe the "no start" symptom and the "car died" symptom too. We
have no idea based on what you wrote if the starter turns over the engine or not and at what speed and engine RPM it died. Did it stall out while at idle or completely cut out at 55MPH? It also would be useful to provide the vehicle mileage, battery age, maintenance history and any recent maintenance performed, etc. The bottom line is that the better and more detailed your description, the better the advice and discussion you will generate on this newsgroup.

When I mean no start I mean completely dead. Started doesn't even click. It
doesn't start only after the car has been hut off and it is very hot and humid out. If it is running it runs fine. This only happen when the car is turned off. I had a mechanic test the fuses and relays under the hood and on the passenger side consol. On the Passengers console he gound the ignition relay was dead. Replaced it and started right up. Worked great for a month and the next hot (over 90) and humid day it did it again, only to start a few hours later. Two weeks after that (yesterday) Hot and very humid it again did it. Replaced the relay with a new one but nothing. Wouldn't restart last night after sitting 10 hours. The car has 67,000 miles, a/c power locks factor "alarm"(horn beeper) and key fob remote. When it is in this state, the headlights and daytime running lights work. The remote does not. Will not unlock anything or sound off horn. Radio is dead and when you restart the car the radio is reset to factory. No work has been done on this car recently as we have not had any problems ever with it.

I had something very mildly like this, but in a different car that turn out
to be a short in a "going bad" starter... When the starter was hot (or just hot / humid outside), when you turned the key to try start it, it would short out and pop fuses on me. (But for me, it also ground out the battery and I ended up having to eventually replace that too as battery's tend not to like that happening to them too many times before they crap out...) I replaced the starter (and the battery soon after that) and was fine...Not sure this is your issue, but you might try there if no one else has any thoughts for you...

(John has yet to provide any details on that failure mode...) Negative battery cable becoming disconnected certainly does cause the car to die while running.

It has never died when running. It runs fine once it has started. After you
have turned it off it does this. I thought I had said that once it runs it runs and doesn't die "Bob Shuman" > wrote in message ... > Doug, > > These were my initial thoughts as well since they are very common issues, > but neither would account for the car dying when it was already started > and running.

Thoroughly clean the battery posts and cable connectors and then re-tighten
them. Also check to make sure the cables themselves are good and that the connection at he starter is also good. As good measure, you can also remove and clean all connections to the chassis and engine grounds too. If it then acts up again, you will know it is either the battery (Car should start off jump fine then) or a problem in the starting system (the starter, starter solenoid, starter relay, or ignition key switch). Good luck. Intermittent problems are a PITA to diagnose ... Bob "John" > wrote in message sburylight... > It has never died when running. It runs fine once it has started.
