2004 yukon denali xl starter and traction control

[Brisolle]

Newbie Here.

I have two problems with my 04 Denali xl.

# 1. turn key on and starter cranks for a while but does not start, I turn key back off then I turn key on and engine ignites and runs normal.

# 2. Traction control comes on at crazy times when I am not losing traction. Car slows down and then returns to normal. (sounds like a faulty sensor).

Is there a cheap fix for either problems. I need to go on a road trip soon and want to make sure car is running fine.

Number one is probably the fuel pump. Mine does that and I am waiting for it to go, but I would try to change the fuel filter first because the pump is expensive. If that doesn't work then go ahead and change the pump. This thread has a How-To video in it. http://www.tahoeyukonforum.com/forum/showthread.php?t=39779&

I can't help you with traction control. 4X4 FTW!
