If your 1999 Saturn SL turns over but won't start, there could be a few different reasons why. Here are some possible causes:
Faulty fuel pump: The fuel pump is responsible for delivering fuel from the tank to the engine. If it's not working properly, the engine won't receive enough fuel to start. You can check if the fuel pump is working by turning the key to the "on" position and listening for a humming sound coming from the fuel tank. If you don't hear anything, the fuel pump may be faulty.
Dead battery: If the battery is dead, the engine won't have enough power to start. You can try jump-starting the car to see if that helps.
Ignition system problems: If the ignition system isn't working properly, the engine won't start. This could be caused by a faulty ignition coil, distributor, or spark plugs.
Clogged fuel filter: If the fuel filter is clogged, fuel won't be able to flow properly to the engine. This can cause the engine to stall or not start at all.
Bad crankshaft position sensor: The crankshaft position sensor tells the engine control module (ECM) when to fire the spark plugs. If it's not working properly, the engine won't start.
These are just a few possible causes of a Saturn SL that turns over but won't start. It's best to have a qualified mechanic diagnose the problem to ensure that it's fixed correctly.
I'm thinking maybe ignition switch??? There you go thinking ??? Thinking an not knowing how to test . You probably should have a qualified repair shop check it. Looks like you just know how to replace parts to no avail.
Do you know what happens when you turn the key to start ?
Circuit Description
When the ignition switch is turned to the Start position, the body control module (BCM) receives battery voltage on the ignition 1 voltage circuit, and less than 5 volts on the off/run/crank voltage circuit. The BCM supplies voltage to energize the RUN/CRANK Relay 32. The BCM sends a high speed GMLAN serial data message to the engine control module (ECM) that the key is in the start position. The ECM receives the message from the BCM, and also receives a serial data message from the transmission control module (TCM) containing the shift lever position. If the shift lever is in Park or Neutral when ignition switch is turned to Start, the ECM supplies voltage to the START Relay 31. The START relay supplies voltage to the S terminal of the starter solenoid, through the 30 A STRTR Fuse 26, in order to crank the engine.
This vehicle's body control module (BCM) has a bussed electrical center integrated into the housing. Body control relays and fuses are installed directly on the BCM, which simplifies wiring and junction blocks on the vehicle. The body control system consists of the BCM and its associated controls. Battery positive voltage is provided to the BCM from IBCM BATT 1 fuse and the IBCM BATT 2 fuse in the underhood fuse block. The module grounds are wired to ground G201, G203 and G305. The BCM is wired to the GMLAN High speed serial data buss, and the GMLAN Low speed serial data buss, as well as discrete input and output terminals to control the functions of the vehicle's body .
Power Mode Master
This vehicles body control module (BCM) functions as the power mode master (PMM). Refer to Power Mode Description and Operation for a complete description of power mode functions.
Hooking up a professional grade scan tool an checking for codes in all the modules on the vehicle ,viewing ignition switch inputs to the BCM is how a professional tech would go about finding the problem .Not guessing an just replacing parts .
car runs great?, and door locks work, work engine running? (key fact not told)key on engine running this fails????????????my guess is RAP fooled you? as it does vast.the car has RAP, and if using RAP and not knowing how RAP WORKS we fail.yes doors fail when RAP times out. sure does.(key off engine off)use door manual levers? manual levers are for safety , to exit any care with engine and battery dead.both Electric windows doors fail.??? and master driver and switches fail on both doors?what battery not told we can not guess what hands did.car main battery LUGS pulled?the door buttons for windows are dead?all; door locks fail too , (buttons)simple it is.KEY failures are:just wires and switches , cave man simple.un like 1990 and back.fuse 29 blown, yes 30 ampsdrivers door ground G300- not bad or both doors will fail hard.all; dead,the problem is in the drivers doorthe module windows switch drivertop fail is wires broken there or wires in hinge boot.or G300 broken or its lug rustynow RAP ( many folk buy newer car discover RAP)and are now confused 1990 had no RAP but thit car doesKEYOFF fails normally>retained accessory power.what is rap?,well it is this silly delay power thingengine runningturn on radio.key off,and things still operate for 10 minutes! bingo RAPor until door is opened AND many things GOES DEAD.(after delay)head lamps by law always work, (and park lamps)is this confusing?, the windows only work if the RAP relay is closed, ,or engine running (keyon)or key off after 10 minute RAP rules,.I will not read the whole 100 pages in your service manual and detail all things that are RAP. sorry will not.Duane tells it to techs. best , best video on earth topic RAPhttps://youtu.be/boUtUHx7T7k
If your 2003 Saturn Vue died as you were pulling up to a stop and the speedometer isn't working now, it's possible that there may be an issue with the vehicle speed sensor or the instrument cluster.
The vehicle speed sensor is a small electronic device that is located on the transmission or transaxle. It sends a signal to the vehicle's computer to tell it how fast the vehicle is traveling. If the vehicle speed sensor is not working properly, the speedometer may not work correctly or at all.
On the other hand, if the instrument cluster is malfunctioning, it could cause the speedometer to stop working. If the instrument cluster has a loose connection or a blown fuse, this could also cause the speedometer to stop working.
It's best to have your vehicle checked by a certified mechanic who can diagnose the issue and recommend the necessary repairs. They will be able to test the vehicle speed sensor and instrument cluster to determine the root cause of the problem.
Low coolant or low power steering fluid would not cause a no-start situation. Call out a mobile auto electrician to connect his pro grade scan tool computer to diagnose. you have electronics, or communication issues.
According to Hollander interchange, the engines are the same from 2004 to 2007. I would change all sensors from your engine to the replacement engine just to make sure there are no issues.
please do post personal economics in public that can last on the internet for 50 years or forever(see, waybackmachine.com)
I will now try to answer this question, (no pointing/wagging fingers!)
based off almost zero evidence, no PCM scans, or how IMMO lamps acts up told at all,or if even present.
"Is it possible to hot wire a 5 speed?I have a 2006 saturn vue 5 speed I lost my keys can it be hotwired".
the simple answer is. (an oxymoron)?
if immo lamp is there (is it?) and blinks wrong, there is no hack.
if no immo lamp at all sure can be hacked.(no IMMO option on this car ) (cut a key and go, locksmith easy)
1: IMMO present it must be repaired in a shop. or dealer.
2: there is no DIY fix for any car with mission keys IMMO
4: there is no DIY fix for cars with less than 2 good key, I can DIY my car with key 3 to 8,but only if 2 keys work ,my same car sold in Canada this DIY is all banned there as it is in vast countries
no VIN told on your car, so most post world wide will lie to you for laws there not the same as your.(a secret)
IMMO kills dead spark and fuel
so yes starter can be hotwired but will never start
IMMO lamp not happy
read the free guide, 1st google hit.
page 96
Passlock--theft-deterrent system. read it carefully
https://www.manualslib.com/manual/149196/Saturn-2006-Vue.html
the lamp goes off , to start in run, mode. not stuck on.
if flashing that is error too,.
im just reading it to you.
A#1 goal and by law is to block all hotwired hacks of any kind
that is JOB 1 , and even more strict now, for sure, by laws too.
and
If the values do not match, the fuel supply is shut off. After three consecutive failed attempts, PASSLock will enter Long Tamper Mode, disabling the engine for 10 minutes while the Theft System indicator on the instrument panel flashes.
there is no DIY fix for 2 lost keys, ever,
DIY,/HACK/HOTWIRES,
ZERO
BEST ON ALL MODERN CARS HAVE 3 KEYS
AND FOR SURE 2 WORKING
if in canada, no DIY there.
also 2005 and 2006 major key changes(designed immo)
the early passlock was resistor codes, then later is passive RF codes.

I;'d say the only best way ,is call real car locksmiths and ask them.
even buy a spare new key first, and save more.
Sadly, this very likely can only be diagnosed by a mechanic who experiences the condition --unless it can be immediately reproduced by said mechanic. And it would be helpful to know the year and whether it is an automatic or manual or if you have any error codes. The following site suggests 13 different possilble causes: https://www.repairsmith.com/blog/transmission-jerks/
I am not sure of the list includes the possibility of bad coils.
The information offered is a little slim to narrow the problem down.
A random/multiple misfire in a 2008 Saturn Vue can be caused by a variety of issues. Some common causes of misfires include:
Spark plugs or ignition coils: Worn or fouled spark plugs or faulty ignition coils can cause a misfire. These components should be checked and replaced if necessary.
Fuel system: A clogged fuel injector or a problem with the fuel pump can cause a misfire. The fuel pressure should be checked and any clogged injectors should be cleaned or replaced.
Vacuum leaks: Leaks in the vacuum system can cause a misfire. These leaks should be located and repaired.
Exhaust system: A clogged catalytic converter or a problem with the exhaust manifold can cause a misfire. These components should be inspected and any necessary repairs should be made.
Engine control module (ECM): A problem with the ECM can cause a misfire. The ECM should be checked and reprogrammed if necessary.
It's recommended to have the vehicle scanned with a diagnostic scanner to retrieve the trouble codes and determine the source of the problem. Once the codes are retrieved, it would give a better idea of what component is causing the misfire.
It's always recommended that you take your vehicle to a professional mechanic to diagnose and fix the problem, as these are complex systems and require specialized knowledge and equipment to fix.
The "service vehicle" message on a Saturn Ion typically indicates a problem with the vehicle's on-board diagnostic (OBD) system, which is responsible for monitoring various systems and components in the car. The message may be accompanied by a specific diagnostic trouble code (DTC) that can be read using a scan tool. The DTC can help a mechanic to identify the specific problem and make the necessary repairs. It's recommendable to take the vehicle to a qualified technician or mechanic to diagnose the problem and fix it.

WHY ARE YOU DOING ALL THIS, ??????
MOST OF THOSE SENSORS DO NOT FAIL, 9 OF 10 ARE GOOD, OWNERS LOVE TO CHANGE THEM AT DROP OF HAT FOR NO REASONS WHATSOEVER. CONFUSED.
THE SENSORS MAKERS LOVE YOU. NO KIDDING
MOST ARE CAM ERRORS. BELT DRIVE TOPS THE LIST

THE CKP IS LONG PLASTIC PROBE, 1 BOLT AND 3 PINS
THE TOP Chains made even GM can go 250,000 miles
more with freq. oil changes
the cheap chain kits sold are pure trash can fail under 50k,
in chains and guides you do get what you pay for.
and no sensor on earth can hide a bad chain,guide or tensiion';er
yes the SM tells you CKP must be relearned
i will post step 3 you will never do, lacking GM tools
