2002 GMC Yukon XL won't start
I know this is a MC forum, yet, there are similarities in car and LT systems... any help is appreciated.
Sunday, My 2002 GMC Yukon XL (yes, it's mine now that it is broken), fails to start.
Before I returned home, the fuel pump was diagnosed as having croaked and my sons have the tank partially dropped, and had the pump out. the new one did not quite seem right.. but what do I know.
Since I'm fighting the flu and respiratory distress, I go inside and await their frustration level to threshold..
An hour later they step up and say, "They gave us the wrong pump"... hmmm
Another 1.5 hours and they have returned with another "new pump" and start assembly into tank.
I go outside to make sure my prodigy are not smashed under the vehicle and ask them... "did you hook it up to make sure it runs?" .002 seconds later I get the "WTF???" look, so I just shut up and go back inside.
Another 1.2 hours and they are about to set fire to the tank because they can't get the retaining ring in place.
.1 hours later I (stupid old man) get the ring in place with a light touch of silicone spray between the ring and gasket...
.5 hours later it's all back together, Battery connected.... ready to crank... Turn igniton "on"... no fuel pump noise... no fuel gauge reading.... (there was about 1/8 tank before replacement)
We "swapped" relays around, checked fuses.. etc... noting "obvious"....
So, I'm still laid up, trying to keep breathing.. my oldest borrows a "test" device and checks the car.. there are NO errors.. zero. But, still no "vroom".
Before I pull the tank completely...again... when I get over a little bit of this illness, what do you guys think the problem is?
1- Faulty "new" pump
2- problem with wiring to pump
