i was driving home two nights ago when my 2001 silverado quit running. the temperature was about 15 degrees. i have never had any problem like this before with this truck. i put the truck in neutral and coasted for a bit. after about one minute i tried to restart the truck and it started up. i drove about another 6 miles and it quit again. this time it did not restart. i called a tow truck and now the truck is in my driveway and it still does not start. it acts like it is not getting fuel. i do have about a half tank full of fuel. any suggestions?

How many miles on the truck? When is the last time you changed the fuel filter, tune up, or you could have even got a tank of bad gas. Add some dry gas to the tank, just a suggestion.. Cound be anything from the injectors to fuel filter to fuel pump, bad gas. Did you happen to notice if the truck was running hot when it stalled?

I'm guessing fuel pump. About $700 to fix. I'm on my third in my '02. Mine's pretty reliable (but everything underneath is a rattly mess) with 197K on it. I've been told to never go below 1/4 tank...supposedly GMs FI is at a higher pressure than the others.

^^^ This. Fuel pump is a very common failure on those trucks. They are generally pretty reliable mechanically otherwise.

WOW 700 for a fuel pump!! I dont charge enough LOL The pump is around 270 and 2 hours to change it. Even at 100 an hour that is still 570.

That rig has the Passlock system on it which Like most of GM's hair brained schemes don't ever work right. Google it and see how the system works and report back.

The correct answer is.....take it to a mechanic and stop guessing. Guessing is expensive and frustrating, and very time consuming...

If its the Passlock system, a GM dealer won't correctly diagnose it much less a mechanic. My 99 K2500 Burb was misdiagnosed twice by GM dealers. Fortunately, I was smart enough not to let them throw the $1000 worth of parts they wanted to through at it. I bypassed the system and all worked fine.

Of course, it could be a fuel pump relay or similar.

No, not really.

On a vehicle line ("Silverado") that offers what...five engines and both manual and automatic trans, you aren't getting far with that.

If that truck has about 145k miles on it, the fuel pump has probably timed itself right to the trash bin, though. I've seen a 96, another 96, a 97, 98, and 2000 in the old body style in the family all lose fuel pumps around that time and the $700 price quoted is for the quality pump part and install. Actually, scratch that. The dad's 97 has about 115k miles on it. Still has time left.

Fuel pressure regulators are pretty bad on Vortecs, too.

Most likely the fuel injector or fuel pump. Do you hear a noticeable noise when you turn the ignition?
