Tahoe 98 having trouble starting.

Throttle body is not hard to remove.
One wing nut/ screw deal to hold the intake tube ontop of the throttle body. Standing at the front bumper lift the rear and pull forward.
Then you need to unplug the IAC and TPS. (Idle air control valve and Throttle Positioning Sensor)
Disconnect the throttle and cruise cables.
Should be 3 bolts and it will lift right off. Take the IAC and TPS off before you start cleaning it. Carb cleaner is just fine.

Yes the scanner should work. Unless it is a different plug, European and older models have some interesting plugs. So it's possible you could have a different plug, but I don't think so.

Your problem may be will the scanner support it.
Here (depending on the scanner) American cars (Chevy/Ford) are very well supported.
BMW, Mercedes, etc... sometimes will not even be on a scanner or will have "holes" that the scanner cannot even show data for that car.

If it will plug in give it a go, worst is it will not communicate or will not show what you need.

It worked. Didnt show any codes tho, And now it starts on the first try.. Its really wierd lol

Maybe it just needed a friend to talk too ?

Maybe.. Its like.. -1 or 2 here, and now it dosnt start again, Once you try to start it it gives out like big black clouds of smoke.. Something is really weird right?! When you're in need of the car, it dont start, all other times it does..

Edit: Once it starts and runs its no black smoke or anything, and is it normal that the ABS lamp is glowing when the engine is cold? :S

the abs should light should turn off a few seconds after engine start. As for the black clouds of smoke you said it just happens at start up and is gone in how many seconds please?

How cold are we talking anyway?

Mine does the same thing, except when it's cold (between negative 10 and 20 degrees) it will not even turn over, just makes a grinding noise. Someone told me it was my starter solenoid going out? Normally I have to turn it a handful of times (4-5) before the starter actually sounds engaged. I had my fuel pump replaced less than 10k miles ago with an AC Delco unit.

Mine does about the same thing when it's below zero outside- turn key and no crank. My fix is getting under pass side and hitting the starter solenoid with a wrench and that unsticks it and it fires right up. First time I tryed this I was pretty shocked that this worked. Got a new starter but I don't mind wearing this one out a bit more, feel like the fonz when i gotta bang on my truck to get it going

Have you changed the fuel filter? Also have ignition module tested. If I remember right it will have a white dot appear on it when they are faulty.

Trouble starting when its like.. -2 or less, Once it gets like +5 or something it starts fine.. Sometimes.

can you get a scanner to read live data from the pcm?
