What to do when my truck stalls

Asked by May 08, 2017 at 11:16 AM about the 2000 GMC Sierra 1500 SL 4WD Standard Cab Stepside SB

Question type: Maintenance & Repair

My truck is a 2000 chevy 1500 and while aproaching a stop light my truck will
try to stall but it sometimes catches its self. Also I will be sitting at a stop light
and it will die. I'm not sure what to do? Any answers. It only does it
sometimes not everytime

First of all, does this happen when the gas tank is full of gas? I had a 1997 GMC Yukon that did similar. It would die at stop lights/signs. Would not start again, then when I filled it with gas, no problem. As you slow down for a stop light, it could be that the gas level is flowing forward and when you stop, it levels out. My fuel pump was internal to the gas tank and when it was removed the top half of it was actually burned, so as the level of fuel lowered the float touched the burned part and showed the tank as empty even though it was half full. As long as it was full, I had no problem. Just a possibility in your case.
