1992 Saturn SL1 - Page 2 - Answered Questions & Fixed issues

Put it back in the factory configuration with a new sending unit,and make sure it is the exact part you need. See if that works. don-ohio

You should be able to get a replacement either at a car parts store or an on-line supplier. It is probably not very hard to change - unlatch the electrical connector and unplug, then remove the clamping screws and pull the old injector out. Be sure to check for an O-ring in the seat; you don't want to try to put in two o-rings (not all designs use one).I assume you know the injector is bad because you have observed uneven or erratic spray from it, or you know the solenoid coil is defective.

it is mounted on the fuel injector rail

There are only 2 types of clutch linkage, cable or hydraulic.
I am assuming it is cable, and it snapped.
Not hard to do. Unattach each end, and remove. When you put the new one in, make sure to adjust it to about a half inch freeplay, unless it is self adjusting.
If linkage is hydraulic, then check the fluid and look for leaks.

Whom ever told you that the Saturn's where hard to find parts for it is wrong. I used to own a 1992 Saturn SL1, and had no problem finding parts at the local Autozone or Napa stores. I believe that your fuel filter is either located on the frame rail just under between the drivers and rear seats; or possibly under the hood in-line just before the fuel rails/ injectors. I wish I would have never gotten rid of mine, it was a great little car.

That is pretty easy. If your Saturn is an SL1 it is single cam if it is an SL2 it is dual cam. That is the only difference between an SL1 and an SL2 - Saturn didn't even bother to put a tag or emblem anywhere on the body to differentiate between the the two models. The 8th digit in the VIN will confirm this for you. If the 8th digit is "7" it is a Dual Overhead Cam (DOHC) engine. If the 8th digit is a "9" then it is a Single Overhead Cam (SOHC) engine. When you have seen both engines, it is pretty obvious by simply looking at them. The DOHC cam cover is much wider and has 2 "humps" with spark plugs and wires going down the center between the humps. The SOHC cam cover is narrow and the plugs and wires go down one side.

Also in the 1992 model year, the DOHC engine was equipped with Multiport Fuel Injection. (MFI) The fuel injectors (4 of them) were located in the top of the intake manifold. The SOHC engine had Throttle Body Injection (TBI) The two injectors were located in the throttle body.

I don't have any pictures of the cam covers, but I have pictures of the cam cover gaskets (AKA Valve Cover Gaskets) you can very easilly see the difference.

check wires and relays there is 2 relays one per lights
you can switch relays to see if problem reverses

could be your thermostst, or, if it just happens in idle, then your electric fan isnt engaging.

Inside of the fuel tank.

On the throttle body you will find the IAC idle control valve, with two wires going to it, unplug and plug it back if no change then bang on the IAC if it goes to normal idle change one with used one and should be fine.
Idle aslo goes high IF a vacume hoses get cracked or come off.

find the starter their should be fat and skinny wire fat fire supposed to have power all times skinny wire should have power when someone turns the key to start position if no power at skinny wire when key turned possible electrical problem, start switch, relay, natural safety switch etc. if their is power and no start bad starter

I'd have a shop look at it, reason being early Saturns are KNOWN for electrical issues - shorting out at fuse box and assorted wiring issues.

Think its time for a new belt and have someone inspect the belt tensioner at the same time...

Yes, adjust or change the belts.

The s-series saturns were known for all kinds of problems with their transmissions, you could have a bad shift solenoid or a worn pressure regulator valve inside the valve body causing hydraulic pressure loss, i would try and service the transmission drain the fluid and replace the spin on filter, if that doesnt help the shifting problems theres more then likely a problem with a shift solenoid or a worn prssure regulator valve both require the top transmission pan be removed, once its removed ohm out the 5 solenoids, the resistance should be between 4.5 and 6 ohms if one or more of the solenoids are out of these values replace the solenoid with a new unit, do you have a service engine soon light illuminated on your instrument cluster at all??

1) you can search and find a video of someone doing it on www.youtube.com
2) you can buy a repair manual very cheap on ebay with instructions and photos
3) you can find instructions and pictures at the reference area at your library in the
MOTORS MANUALS

unless that PS fluid is special fluid that you added The two PS and trans fluid are the same and won't hurt that trans at all..

A car that old is not worth rebuilding the engine. For the price of an engine rebuild you can buy a 99 Saturn with half the miles. Or you can call a junkyard and see if they can locate you a SOHC saturn engine to fit a 92, probably any Saturn SOHC up to 95 will do. Used motor will cost 300-400 dollars plus removal/install while a rebuild will cost you 1500 at least plus a removal/install.

Where all O2 Sensors have been for 25 years
In both ends of the converter
Some times, just before converter in exhaust pipe

An O2 Sensor Code---Does Not mean it is bad or has to be replaced
The code indicates it went out of range

You need to find out why.
Then only if you test it, and it has failed,would you replace it.
