1983 K5 Transmission Controlled Spark System

Anybody know anything about the TCS system on the 1983 Blazer? I'm changing the engine but am not replacing the emission control equipment. Will that affect the transmission's operation?

I heard that in most cases with the code PO44O it is just a "Loose" Gas Cap. You need to make sure the cap is turned until you hear several clicks. Then reset code and hopefully the light stays off.

More then likely its the Canister Purge Solenoid. you can find it online at www.autozone.com the part number is PV140. And to replace it on blazer you have to remove the spare tire. Alot of people don't know where this part is so I hope this helps you and good luck.

I had this probelm, we found that the throttle body gasket was letting air in through a tiny pin hole, new gasket fixed it. You have rebuilt yours, maybe check the seal. Be sure and use a new gasket.

The best thing to do is to buy a Chilton,s repair manual. It has step by step procedures. You can get one at most auto parts stores. They coast anywhere from $10-$30 dollars.

My 86 chevy k5 blazer with carburated engine will crank but not start


As with any no-start situation, you would need to know if the plugs are getting spark and if the carb is spraying fuel into the intake.

Airbag warning


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms

On my Toyota Sienna 2008, my check engine light, Trac Off and VSC lights are one. Why? How do I fix it?


On most Toyota's that are equipped with Cruise Control (Vehicle Speed Control or "VSC") and with Traction Control System (TCS or "Trac") all of these lights will come on at the same time if the Engine Control Module (ECM) determines that there is a fault in the engine management system that 1. Prevents the engine from being properly controlled. 2. Prevents the VSC from being properly controlled 3. Prevents the TCS from being properly controlled 4. Any combination of items 1,2, and 3.
Most of the time it is caused by a single fault in the engine management system. Fault codes are codes that are output by the ECM to let a diagnostician know which of the many systems, that are monitored by the ECM, is malfunctioning. To find out what the actual cause is, you must scan the ECM for fault codes then use this information to begin diagnosis of the system that the fault codes point to.

Check engine light on an 85 k5 blazer


a simple way to see if the check engine light works is to unplug any sensor and if the light comes on then the light works and the computer is doing its job(to turn off the light simply plug the sensor back and disconnect the negative cable on the battery for 1 minute)
