1999 Saturn SL2 Electrical Problem--Help!!!




By hjletendre on Jul 31, 2008

" "
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 found my old extra security key they gave me to keep in my wallet when I bought the car new in 99 and even followed the "reset" directions in owners manual for alarm---but it's deader than a doornail this time---something's really blown and it's not those relays as I put new ones in...but thanks!

-   1999 sl2 stalls when driving or sometimes at start time. very intermittent. clock and radio always lose time/settings when car fails - even won't get reception only static when car is trying to turn over.. after numerous trips to mechanic who kept saying it was fuel pump/filter- now they tell me today they got a code on it and it's the crank circuit. perhaps the other times it was in shop car wouldn't start so couldn't get code. am hoping this $23 part will fix problem this time as car has been great other than this. i used a walmart copy in my ignition when i first got car 4 years ago and it's a tiny bit too long and i don't know if it messed up the ignition or what, but i only use my saturn key since experiencing problems early on with turning the copy key.-   daniryr2

-   I have a 1999 Saturn SL2 and it has electrical problems but very cold here 18F. About a week ago I started my car and the lights came on and off then it stalled. I restarted it with no problem. Then a few days ago the speedometer and the RPM dials would go to zero as I was driving on the highway and then go back to normal. The engine did not stall at all this time. The same day I stopped at my Moms to shovel snow and when I went back out to start my car there was no power. I tried again a half hour later and there was power to the clock and dome light but the engine would not turn over. -   srvohio

-   Hi,
I've had a sort of similar problem on my 1996 SL-2. Mine has a small security key right next to the ignition. I just leave the key in all the time. When my car won't start, I take the key out and put it back in and it usually fires right up. I don't know if that's helpful at all.-   Guest

Circuit 402. Loose terminal at the instrument panel junction block. Go to the back side, drivers side of the fuse block and reove the grey 64- way connector. A 7mm bolt in the center of it. Look at all of the connections, possible hot spots, if terminal F5 looks hot, replace the terminal and the fuse block.
