Plugs and wires for old style 2000 Tahoe

TX-TahoeLtd · February 5, 2005

Hi,

I did a search and the information I found was for the 5.3L engines.

I've got 70k on my 'old style' 2000 Tahoe with the 5.7 - can anyone give me some suggestions on what plugs/wires I need for my truck?

Also - what about fuel filters? Hard to replace?

I've got a startup problem after it's been cool outside and the truck sits for a while. I carpool to work so it sits there for ~a week and it's starting to turn over a few more times (like 10 or so) before firing up. Once it fires, it's pretty smooth and runs very well. I haven't noticed any significant drop in mpg either.

Think plugs/wires/air-filter(time to change, i know it's not part of the problem)/fuel filter will help?

Also - once it starts up it's fine after that for the next few days until it sits for a while.

Maybe she's just mad at me for not driving her more. ;)

I bought a "tune up kit" from Summit racing. Plugs, wires, cap and rotor. All made by Accel and good quality and performance. About $100.

The fuel filter should be along the frame rail under the driver's door. Not too hard to change. Just go easy with the wrench, put the new one in correctly according to the arrow on the new filer, and make sure you have something to catch the small amount of gas that will run out when you remove the old one.

When changing the filter go through this procedure to keep from getting sprayed in the face with fuel.

1. Open the hood and take out the fuel pump control relay.

2. Start the engine and let it run until it dies from lack of fuel.

3. Now you can undo the lines to the filter and there will be no pressure on them.

When you order wires or plugs, just make sure you tell them you have the 5.7L engine. A lot of places get confused by the carry-over models. You can just tell them 98 Tahoe if you want.

MSD makes a killer set of wires for the 5.7L

I like the MSD stuff, great products, reliable. You would be best off getting the wires, plugs, rotor button, and cap. If you want to spend a few extra, go for the MSD coil as well. Great combo!

Thanks all - I ran to Pep-Boys and gathered all the parts.

I'm 2cyl shy (back 2, psgr side) of completing it - just ran out of time yesterday.

This was my first time doing anything like this and it was a little more difficult than I had expected, especially getting the cap off and put back on. I had to climb into the engine bay to figure out how to get the dadgum thing off.

Just took a little patience and lots of elbow grease.

Anyone know what's in that box that sits up on top of the throttle body that is labled 'vortec'? Anything that needs to be changed out?
