What did you do to your OBS GMT400 Tahoe/Yukon Today?

Fuel Pump and Tank

I replaced my fuel pump. When I dropped the tank it was rusted really bad and when I peeled back the padding used for vibration control, it had trapped tons of dirt and moisture. Guess what? It had a hole so I had to order a new tank. I got it from Advanced and used the "VISA" promo code on checkout and got $50 off plus another 15% on a sale they were having. I primed and painted everything including some rust spots under the body and the tank sheild. Felt good to get that done. My wife thinks i'm crazy!

I had the pump replaced about 5 years ago from a shop. It had a Carter in it with the original style connector on it. Here is a side by side of the Carter and Delphi guage rheostat. The Delphi looks like a much better pump overall.

The hardest part was getting the fuel lines off. The larger one was an oddball size. None of the disconnects I had fit, plus the carter had all kinds of addition plastic support around the pipe. I had to hacksaw off the tubes and mess with getting it out of the connector. POS Carter!!

So now My fuel pressure is a rock solid 52lbs. I posted a video here (http://www.youtube.com/watch?v=9vVNMj7Gsh8) to see if anyone thought the pump was going and really noone had seen an erratic fuel pressure reading like this. Turns out the pump must have been on its way out. I was actually trying to diagnose a p0300 issue but it still lives on. However it does run smother and idle is much more stable.

Here is the new video of fuel pressure. (http://www.youtube.com/watch?v=9rsRvBdvUzo&feature=channel&list=UL)

in ten days going back to have PS pump replaced. the reservoir seal is leaking and it has been run dry several times as a result. so a new pump and reservoir will be ordered with provisioning for a hydra-boost change over later on. $101 from Amazon for a remaned delco unit with no core.

WOW ! msd ? cap burned out after 12k miles and 9 months in service.

Doesn't look like there was any contact grease used anywhere on that cap and rotor and it looks like aluminum points at that. Next one, buy one with copper points and slather them in dielectric grease.

Good point,looks like aluminum points at that,Hmmm ,MSD

Actually the cap is brass terminals. Can't explain how it got corroded like that so fast. And why would I throw electric grease on them when I need to move thousands of volts right thru it? Kinda defeats the purpose. But if you mean inside the cap in the terminal pits I can not ensure the grease will always stay there. there is a delco unit now and the msd cap was in excellent condition on the wire side. I may have to consider looking at venting the dizzy assembly some how.

So I ended up buying my set of Bilsteins off of the Denali I just sold to a family friend. I had just put them on the Denali right before I sold it. He apparently didn't like how stiff they rode. So now it looks like I'm swapping out the brand new Monroe reflexs for the Bilsteins.

My Dad drove the blazecalade over 200 miles to his shop. He said it ran like a champ! He changed out the shift solenoid prior to leaving.... Happy to have the blazecalade up and running again
