Whining noise while in idle, sputtering, car tries to die while driving, wouldn't start initially then would start after a period of time.
The
following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
The
Engine and Automatic Transmission (not applicable to manual
transmissions) in this vehicles drive train are fully electronically
controlled by a computer called the PCM and TCM (Power Train Control
Module, Transmission Control Module). When a problem like this or
other drive-ability related problems occurs the computer stores a
record of the problem (there are of course some exceptions to this,
like the fuel pump, engine coolant temperature sensor and MAF sensor
for instance) in the form of a fault code in its memory, to read
these fault codes you must have the systems memory scanned with a
special tool. Once the fault code(s) are read you then must perform
the appropriate diagnostic testing to find and resolve the problem(s)
DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED
THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT
MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for
correct spec for your make and engine type.
Also engine mechanical problems ca cause many drive-ability related
problem such as rough idle and other symptoms

almost positive its your fuel pump letting you know its time for a new one.
Could also be; control module
coil
crank sensor
battery with internal plates touching
fuel pump relay(i would change this one regardless)
Your OBD1 should have a stored code and that will probally lead to your pump or relay.

Hi there.Hope this can help.On the top of the transmission there's a black electrical plug that the shift linkage goes in..It sounds like the range sensor is out of adjustment..If you try going from reverse to like first or second does it still stall.You may have to get it adjusted.Does the selector in the car where it say P R N D 2 1 Line up with its indicator.

Not to mention the condition of the fuel pump which is a weaker link in this vehicle.Key on/eng off cycles this pump for 3 seconds and that gives you some opportunity to listen for this pump in the fuel tank. New units sound smooth and quiet...a failing pump sounds louder and squeelish. After replaceing that suspect filter (located along the driver side frame rail under seat) have a listen to the
pump and they work about like they sound it seems.Verify fuel pressure if possible.
SOURCE: whining noise at idle & gets louder when
gonna have to localize the noise alittle further...
SOURCE: blazers in park = rattling
have you had the catalytic converter checked. When they break apart they will make a rattle ling noise. eventually the broken pieces will plug the exhaust and cause a lack of power feeling. When the exhaust is cold hit the bottom of the catalytic converter with your hand. If it rattles it is bad and needs to be replaced.
