Map sensor troubleshooting
We have 96 toyoto camery. It will start then it will die for no reason. Take the map senser out it will run. Just uses a lot of gas. Is it the senser or something else.
Fuses
hi if you look on the lid of fuse box it shoud be on there or in the hand book
Engine
Brake booster is possibly leaking
Car wouldnt start after being hooked up to a battery charger for 24 hours
It could be water frozen in your fuel system (fuel line, fuel filter, fuel pump or pickup or fuel rail). If you can get the car into a garage try letting it warm up, otherwise wait for a warmer day, to try starting it. If it is water in the fuel, you can add "dry gas" to your fuel which is an alcohol product designed to be an antifreeze and to absorb the water. However, if the water is already frozen in your system, this won't help without warming the car up first in some way. If you haven't changed your fuel filter in the last year, I would do that as well. Water can easily build up in a filter and freeze there in extremely cold weather. If this problem is water related, also fill the tank completely with a fresh quality gasoline, and add dry gas for the next several fill ups to help get any water in your fuel system out to keep it from happening again.
Won't pass smog when it should...
Just because the car seems to run well, does not mean the emissions are within spec. For example, you could be running a little rich and the car will start and run great, but the exhaust is not within code.
What you can do is take it to a "smog shop", that is a repair shop with the proper equipment to diagnose the problem. If the testing is simply the reading of the on board computer codes, then most any place can read those, but you need an experinced mech to know what to do about it. May need an exhaust gas analyzer to physically sample and analyse the gasses. For the actual test, as long as the computer says all is fine, usually, you're good to go.
If the computer looses power any saved run data will be lost and must be re-accumulated to pass the smog test. A few hours to a day is usually enough run time to accumulate enough data.
No spark
have you looked at the CPS that is sitting just behind the starter ?
Engine idle
check for vacuum leak, idle speed is 700> rpm
SL1 randomly starts sputtering while driving, then
Saturn i think this is the same car or the same engine and software type as our opel vectra /zafiro range and if so then these cars from this age are notorious for dodgy ECUs ,the faults are varied but basicly the same but this one is only the idle and no fault lights on so i would suspect a FAULTY STEEPER MOTOR so renew this first and see what happens if that doesnt work then consult a local mechanic with saturn experiance
Engine is old
My personal preferrence would be to swap or get another car. This particular car in my opinion doesn't hold the value of cost to rebuild the engine. Just my opinion.
ABS light stays on on a 1999 sat urn sl2
ANY Dash Light you get, that comes on or stays on afterthe motor is running is a possible problem & a possiblefault code should be checked forI'm at a loss with this site & the questions, because we have had these codes & vehicle systems for well over 30 years, yet no one knows the vehicle is in trouble & you have to check for codesYou need to run to a repair shop within a day, every time anydash light or check engine light comes on,not ask questionsor continue to use the carAny codes you get can be googled, to find the system that setthe fault light
