Question about 2001 GMC Yukon
Why does my 01 GMC Yukon stall out while driving? Cranks right back up after you turn it over about 6 to 10 times. No check engine light on. Acts like it is out of gas. I have replaced the catalyic converters, fuel filter and pump, and throttle body has been cleaned. Very frustrated please help!
Check throttle position sensor, IAC Valve, and loose or leaky vacuum lines.
Hopefully fuel pump isn't bad.

I would check the fuel pressure regulator. Make sure there is vacuum going to it. Also, there is a screen in the fuel pressure regulator, that screen could be clogged. I would also check the fuel pressure just to make sure the fuel pump isn't defective. 4.8 Liter or 5.3 Liter?
