No oil pressure at start up, 2001 Tahoe

[rook]

Ended up being the oil pickup grommet failed. About an $8 grommet did all this. Fixed it, I have some other posts...

k, have my fingers crossed. I did see some video's where they unbolted shaft housing from the cv joint, it was enough for the diff to drop without dropping it more. Did you try that? I have had to do this in my other one, the hardest part was putting the diff back up.

There was another post that said this could be done without dropping the diff. So, probably could be done. I just chose to pull it all down and power through since it was all pretty easy to get to.

Had the same low oil pressure problem at start up and slowly built as it warmed up, pulled the front off and changed the oil pump and o-ring, found the o-ring flattened and cracked so that was probably the culprit but with 219k on the engine a high volume pump was a logical choice since I had it apart, did the water pump and thermostat at the same time. 60# at start up now and 210 on the temp and shes very happy now!!

Why did you go with the HP pump? I read that you do it if your not building up enough oil pressure, is there really any down side? I have the pan off right now. On the 6.0 with electric fans, is it that much more work to do the pump or is it still a ***** to do? Kind of 50/50 on this. Only reason is that the pan is such a pain with diff, although I finally got smart and got a tranny jack.

You've got to take the front off. I looked at an oil pump too, wish I could have done that at the same time. I was just trying to get the rig back up, given it was my wife's only ride to truck around our kids...

Yeah, I am committed. I dropped the pan last night. The o-ring did not look that bad. Taking the front off.

Ok, so I can't get a GM puller, so the Chrysler one will have to do. Since I am removing the starter, thoughts on replacing it? It's the original, do these usually last forever and very reliable?
