I dont know a thing about cars..so could you fill me in about what is going on? Thanks :) ????? Your vehicle transmission is electronically controlled by a computer , without hooking up a factory or professional scanner an checking sensor data parameters to the PCM - powertrain control module ( computer ) an codes ,we'd only be guessing . Your best bet , take it to a qualified repair shop an have it diagnosed .

If you ran it low find out where the oil is going leaks seal's put a large piece of card board under your vehicle tonite and check in the morning.do not move until you check.As far as the tick that sounds like a bad valve lifter or damage to your engine.

Test the connector to see if it has power with a multi-meter. Corrosion plays a big factor. But considering it is a 2003 I'd probably say it is the motor considering you changed the fuse.

Sounds like your key is no longer actuating the starter/not matched to the vehicle key code, if you can turn it on but no cranking action is done when trying to start.

Maybe a broke wire inside the rubber boot from the body to the door ! See this a lot. Opening an closing the door a million times . Do you have a volt meter ? Pull the switch from the door an test for B+ voltage on the brown wire at pin G connector 1 The other window switches get B+ from the drive door switch . Also check the ground , black wire pin B connector 1 . Do you know how to use a DVOM - digital volt ohm meter ?
Videos on youtube .

Hey DaisyMae
I do not believe its the ignition switch.
Sounds more like the battery is not making really good connections or its a bad battery. Take the battery and have the CCA (Cold Cranking Amps) checked.(the true measure of the quality of a battery).. Home Page Reilly Auto Parts These people can check it. If the battery checks good, make sure the battery connections are clean and TIGHT.. NOW - ..IF the same clicking still happens, time to check the starter solenoid and starter, -(make sure their connections are tight) ... the solenoid is located on the starter. IF ya'll are mechanically inclined you can remove the starter/solenoid and it's back to O'Reilly's for a check... Your problem is 99.99% one of these items. (disconnect the battery when removing the starter)..
Please rate as helpful ..if this helps..thanks and good luck.

Why would you do 10 minute key trick ? Is the SECURITY light on steady ? Just a code reader ? Checks just Engine PCM codes ! Need a professional type scan tool to check codes in the BCM - body control module ! Don't know what and how much you know about these GM vehicles ? The ignition switch is a low voltage input to the BCM ! To determine power mode , off ,ACC , run , crank
On vehicles that have several control modules connected by serial data circuits, one module is the Power Mode Master, PMM. On this vehicle the PMM is the BCM. The PMM receives 3 discreet ignition switch signals to differentiate which power mode will be sent over the Class 2 Serial Data circuit.
To determine the correct power mode the PMM uses the following circuits:
• Ignition 0
• Ignition 1 voltage
• Ignition 3 voltage
Discrete Ignition Signals
Those modules that have discrete ignition signal inputs also remain in the state dictated by the last valid PMM message received on the serial data circuits. They then check the state of their discrete ignition input to determine the current valid state. If the discrete ignition input is active, battery positive voltage, the modules will fail-safe to the RUN power mode. If the discrete ignition input is not active, open or 0 voltage, the modules will fail-safe to OFF-AWAKE. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle . If you don't know anything about this your best bet , take it to a GM dealer . Without knowing what state the BCM is in or seeing from the ignition switch or if DTC'S - diagnostic trouble codes are stored , can't give you any sound advice . Would only be guessing !

Did you try Head gasket fix I had 99 3.4 works well?

You most likely need a new low beam headlight BULB.It has the low and high beam in it and the separate high beam has only high.
You SHOULD have 2 tabs ,one at each end to pull up and the headlight assembly should then come out easily.
Tapping a blown out headlight can reattach the filament for a short time but after that replacement is necessary.

Get a definite diagnosis. It could be many things but it sounds like the trans is starting to show signs of wear. If its still under warr. take it back ASAP

If you have 100,000 miles or close to it you needed or would need a fuel pump anyway.Your mechanic sounds like a knowledgeable skilled honest one, he didn't even charge you for some items.
Stick with him/her as you both will get all the problems solved.
The work he has done is smart logical work so far.
Next time it does not start right away,keep cranking the engine to get the oil pressure up.If it starts when the oil pressure builds it may be you are not getting a prime cycle when you first turn on the key some times.

Try a mechanical grabber, which is a flexible cable with a push-button on one end, and grabber-claws on the other end.

I assume the symptoms are a low brake pedal? If so the master cylinder may be defective.
