Saturn Sl2 2001 Check Engine, Service Engine Soon, Engine Oil Pressure, Charging System, Airbag, and Gas lights all stay on the dash.

Asked by Jul 16, 2016 at 12:40 AM about the 2001 Saturn S-Series 4 Dr SL2 Sedan

Question type: Maintenance & Repair

I've had my lil car for about a year now, running at 115k miles. So far I've
had to replace the water pump and the radiator to fix other issues, but
nothing major has gone bad. Now occasionally when I start the car all the
above lights will light up and stay lit as I drive. If I pull over and kill the
engine and restart the car SOMETIMES they will turn off(They don't turn on
100% of the time I start the car, only like 30-40% it seems). If I let the gas
get below a quarter tank all sorts of odd things start happening, she doesnt
want to start and gives me electrical trouble (electric locks stop working for
no reason even though there is still power). But if I just keep gas in the car
those don't manifest. Also when I start the car the rpm hits like 1k then
drops to like 700 before idling back at like 800 or 900. Don't know if that
matters. So I've attached my code reader and it keeps giving me no codes
found, even with all the lights on. I only post now because the other day I
started the car in the driveway, it started fine but the lights mentioned
above stayed on, then I put it in reverse to back out of the driveway and it
clunked heavily as soon as I shifted. Like it tried and failed and the engine
instantly died. I tried to turn it back on and it wouldnt start. I went inside,
looked stuff up, then went back out and tried again and it starts. Everything
seems to be functioning now, but that seemed like a pretty big sign I should
have the car looked at. Any advice on what I should do/start looking would
be nice. I've searched many threads and can't find a situation exactly the
same as mine. Let me also say this is my first car, I'm trying to do all the
repairs myself to learn and whatnot, so please be patient if I was sub par
describing the situation so far.

Okay I don't know the personal history of your vehicle and it's great the way you described everything but can you describe what maintenance that you've done to the vehicle because you really have to start there like have you done a complete tune-up on the vehicle? One thing I learned from the Saturn fan club is that your temp sensor the coolant temp sensor can go bad and there's an updated sensor that's non ceramic & ist now all-brass because the ceramic one was corroding and falling apart. You can install that new updated design one it won't corrode, when the old one goes bad all kinds of crazy things happe so I recommend replacing that. Additionally you should go through all your fuses make sure they are all correct and make sure all your wires are tight around everything all your connections are tight just go in the engine bay and play around with all the wires grab them and play with them see if they're loose or tight your battery terminal connections make sure they're tight the alternator power cable make sure that's tight excetera good luck sir get back to us.
