u hav to take oilpan off. u might also hav to take motor mounts loose and jack up your motor away from k frame

there are two lines that connect to the radiator. they are tubes and have special nuts to take loose. u can use open end wrench but be careful not to round the nuts off. have a pail to let the tubes drain into so you don't spill trans. fluid.

if your battery is low on charge or you have to jump it off it may already be engaged and stuck in flywheel try turning motor by hand back and forth listen if you hear it pop out then try to start with good battery if doesnt work replace starter it could be the selinoid switch but you have to pull starter anyway so just replace all of it

Do you live in a damp area such as near the water? It sounds as if the ignition wire are a little porous and need the heat of the engine to dry out. There are many other issues that can cause this but is the first lace I start when these symptoms appear. Also, while the vehicle is mis-firing, does the 'Service Engine' light flicker?

Good you have tried it! I pressume all fuses and relays are fine. Check if there are broken wires from the main source of the distritbution fuse boxes. Now, try to supply the said relay (from the left) using jumper wires from the distribution fuse box voltage source. Goodluck.

Water in oil makes the oil go grey / milky or white . Check the cooling system by a pressure test and if it is holding then it will not be water in the oil.. If you are referring to transmission oil then the tan colour indicates burnt oil, and must be replaced. Water in that oil will also be a white cherry/ milky colour.

Tan color... or creamy color is kind of a bad thing... But, before I panicked, I would change the oil and filter and start from a new beginning.... IF, after running it for a day or two, you again have a problem, you are somehow getting water or engine coolant into your motor oil.. and that can happen several different ways..... and most of the ways are "bad"... Good luck...

The accelerator cables? Spray them up good on the outside with a penetrant spray, like WD-40. The problem with sticking throttle body parts (like the butterfly valve, and the idle control valve) is not carbon deposits, it is coking deposits. This is from air impurities. Remember that a hose from the PCV system is routed back into the air intake-this carries a lot of impurities. Over time, coking deposits will build up. Air passages controlled by the idle control valve will get these coking deposits. I'm not sure how much the internal carbon cleaning helped the throttle body. I believe I would get a second opinion- I have never heard of an idle valve that can't be taken off and cleaned.

test output of turn signal switch both circuts go thru switch

there is no reset button on GM's, check for clogged fuel filter and or low fuel pressure/volume

The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well. http://vatspasslockpasskeysecurityhelp.yolasite.com/
