Asked by Treytibbs86 Aug 31, 2020 at 12:51 PM about the 2001 GMC Yukon XL Denali 4WD

Question type: Maintenance & Repair

was heading to work this morning and I was coming
around a turn. When I came out of the turn, I hit the gas
hard, then my truck died. I tried to start it but It would
crank, but wouldn't start. I checked to see if the fuel pump
would prime when I turn the key to run, and it did, but when
I check the fuel pressure, it showed zero, I thought maybe I
was out of gas, so I put gas in it. I let it prime again and
still no start. I have four codes on my obd scanner ,p0140,
p0135 p0322, and p0327. Which is knock.sensor, 02
sensor and cat converter, but my cats have been hollowed
out. I did just get the bully dog gt tuner. Any suggestions
on what it could be?
