What's this he's asking...I just ran into the same problem

you have an electrical problem somewhere a shorted wire could be touching the frame. Try checking your battery connections starter connections and wear rubber soled shoes

Sounds like the security system is causing your problem. Is the "security" light flashing? If it is, turn the key on, leave the key in the ON position for 10 minutes. The light will stop flashing. Now, turn OFF the key, turn it back to ON, and then crank it. It should start. If the security light starts flashing again, go through the process again until it starts. This is resetting the security system after the battery has died, battery has been changed, radio was changed, instrument cluster was removed and replaced, etc. Hope this works for you.

The crank sensor generates the signal for the ecm. Every revolution of the crankcase sends a momentary impulse to the ecm. That data then gives the ecm the info with which to properly coordinate the firing of the spark plugs and other critical components. When testing the sensor most important thing to do is make sure that the sensor is receiving the 12 volts of power on one hot line and then if confirmed you check out the remaining power line for the impulse as the crank rotates. If you detect the impulse then you know the sensor is working.

Hope this helps

The Internet, though, has a large number of web sites where you can buy service manuals and schematics from bookstores, publishers, and other collectors.

check the refrigerant level

You find where the leak is and replace that part of the line with the same size line and then you need to bleed the brakes and get the air out of the line. Be sure when you bleed the lines the master cylinder always has fluid in it You will need someone to pump up the brake and hold it and do not take there foot off of the brake when you have the bleeder at each wheel open or you will suck air back into the system.

You need to remove the rear end plate and then the c locks can be remove with a pair of needle nose, you may need to move the axle either in or out to get some clearance to do this or loosen the c lock. Just be sure to drain the rear end before you pull the cover on it.

If the engine has been blue printed with different pistons and cam the best way to set the engine time is to loosen the dist so you can turn it and then start the truck and move the dist to the rear until the engine misses or slows and then move the dist forward until the engine smooth's out and runs smooth. Once this is done quickly step on the gas and the engine should respond right now with no hesitation. You can also use this method for a regular engine timing setting.

Not sure on a 2001 but they are either under the dash on the driver side or under the hood in the black box marked fuses and each one is identified as to where it goes.

Here is how to test fuel pump....also check for clogged fuel filter http://www.bing.com/videos/search?q=2001+chevy+silverado+how+to+test+fuel+pump&qpvt=2001+chevy+silverado+how+to+test+fuel+pump&FORM=VDRE#view=detail&mid=AE270CE3C22ABEF14F34AE270CE3C22ABEF14F34

Vacuum Leak or bad fuel or fuel pump

Either ASD relay or starter fuse

check the wiring

There are so many factors involved - bell housing bolt pattern, engine type, etc. you are better to get a trans out of the same configured vehicle.

check Ytube.

Same post again? Look at two AC pipes entering heater box. One is low side (large) and one is high side (smaller). Disconnect the high side pipe union and inside the pie going into heater box is the orifice tube.
