This is often a sign the plug isn't firing correctly. Is the engine running rough at idle and under power? Using insulated grips, with the plug out and fitted into the plug wire, hold it against the engine block. Get a helper to crank the engine for NO MORE THAN 3 seconds. Look for a strong blue spark firing evenly. If there is no spark or it is weak replace ALL the plugs with new ones and recheck #2 after running the engine.

Check the switch that is under the dash on the brake pedal arm.

My personal suggestion would be to try www.reliable-store.com instead. much better info on all vehicles, complete details, and they also have live assistance feature

Get manual online under $10-15 and get complete guide on whether to repair or not, service it, and how to repair etc you can get it from reliable-store or manualslife really good plus instant help also available

I think there is a wiring connector in the harness that may be loose or corroded. Trace wires from back to front.

There are two vent/purge valves - one on the engine that takes vapor from the gas tank and cycles it into the intake manifold. The other one is connected by a hose to the vapor canister. I don't know which one you bought, but it can't hurt to replace both - the one that fails most often is the one connected to the canister and is usually mounted under the vehicle at the back. It often fails due to road contamination getting into the solenoid.

for 4wl need to be stopped and put in neutral or park it wont actuate while driving [ blinking light indicates failure to engage ] 4wd hi can do while driving --if fails also then check and test for actuator sticking --control module --or transfer case failure

Your wrench size should be 22 MM and the thread size should be M14-1.5 and its a right hand thread

Visit the on-line store, known as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem. 2001 CHEVROLET SILVERADO 1500 PICKUP REPAIR MANUAL

Make and model, year, engine, transmission? 2wd/4wd, ever been wrecked, etc. could be drivetrain parts such as c.v. or U joints. could be fuel system clog somewhere. could be a bad sensor. We will need more detailed information.

It sounds like you have a ground problem. Have you checked to see that the "new" battery is fully charged? Have you checked to see if the starter motor is getting current when you try to start the truck? Have you checked to see if the battery cables and terminals are corroded, or the cables themselves corroded at any point? You also might have an ignition switch problem due to age or use. You also might have a computer problem that is keeping the circuits from connecting properly. If you have a OBD II scanning tool, it might well tell you exactly where the problem is. Scanners are inexpensive and available almost everywhere. I bought mine through Amazon for less than $25 including shipping.

Did you hook up a professional scan tool , check sensor data to the PCM - engine computer ?

What ????????????

Remove plugs and check compression, maybe burnt valve, unseated valve

indicates injector problems and possible low fuel pressure run the fault codes to check for EVAP and blocked cat converters

If the transmission isn't shifting out of second, it's in "limp in" mode and there will be a trouble code stored in the computer. Start by getting the trouble code instead of trying to guess is a certain wire is the problem

Yes we can ! With the light on and or flashing , DTC'S - diagnostic trouble codes are stored in the 4X4 control module . Have the codes check , not at auto zone or any other parts stores . There code reader tool will not pull this codes . Need to take to a qualified repair shop . Testing also needs to done , not guessing an throwing parts at it . This 4X4 system can set a number of codes .

The encoder houses 4 Hall effect sensors that are used for channels P, A, B, and C. These sensors provide a path to ground, when a magnet, (part of the Motor Encoder), passes over them. The transfer case shift control module supplies an 8 V reference and a ground circuit for the encoder hall effect sensors to function. The transfer case shift control module supplies current limited 5 V on all the channels, thus as these channels are pulled to ground, the module can interpret the location of the transfer case shift position. This DTC detects that the transfer case is unable to successfully complete a shift to a requested mode or range.

Hey RPG, There is a sensor on the side of the output shaft (Speedo).. Mine had become covered with metal crud and would not work,, pulled it out, cleaned it,..(replace the o-ring on the sensor!!) and it ran fine.. This might not work for you, but it did for me. Next.. take it too O'Reilly's, Auto Zone, or Advance Auto and ask the to scan you truck for a trouble code..(free) and see what turns up.. Good Luck.. https://shop.advanceautoparts.com/ Home Page Reilly Auto Parts Save 20 On Online Ship To Home Orders Of 100 Or More

Does the vehicle start an run ? If it does ,the brain as you call it is working fine . The check engine light has nothing to do with the PCM /ECM sensing problems .You probably should take your vehicle to a qualified repair shop .
