My 06 Silverado, 5.3 L , stalled out at 65-70 mph , then restarted, 8 times on a long trip home. The 9th time it would not restart and I had to pull over. I waited 45 minutes after trying it several times. Meantime, I tokk off and replaced the gas cap, and cleaned the air filter. It was ho, over 95 degrees. The last time I tried it, it started right up and ran fine all the way home about 140 miles. Starts OK now. The engine did not sputter or buck when it quit - just quit like a light switch turning off.
Sounds expensive to diagnose and fix as I know there can be many different causes. Any ideas or has anyone else experienced the same problem?

Thanks biga4! I was having the same problem with my 2000 GMC Sierra 1500 4.8LTR V-8 you described in your post. I had changed out all eight of the coils along with a new fuel pump & filter (the fuel pump was causing a lag whenever the fuel in the tank was 1/4 full or less) but I was still plagued with rough idle & hard start. I changed out the FPR ($64.64 at O'Reilly's) and it idles smooth and starts right away even after having reached operating temp. You da man!!

I have a chevy 3500HD. I was driving down the road when all of a sudden the truck just lost power like it was out of fuel (I don't know much about diesel motors, this is my 1st one). I checked to see if there was fuel in the filter by cracking the bleeder screw and nothing came out. A friend told me to get a new filter as the one on there may be plugged. I replaced it and I cannot get any fuel into the filter by priming it. What could possibly be the problem??

I apologize for your frustrations. I would recommend speaking with the dealer to have the vehicle diagnosed. Can you please update me on your progress as well as send me your information (VIN, current mileage, dealer etc.). I look forward to speaking with you.

Thank you for your response, my truck is at Steve Schmitt GMC Chevrolet in Litchfield, IL. I currently don't have my VIN number handy, the truck has 150,000 mi on it. So far as of today they think that it might be the fuel injection pump. Unfortunatly they may not have it done till Monday, I need it tomorrow so I can continue my trip as I deliver new 5th wheels and travel trailers for a company out of Indiana. I was on my way to Texas when this problem occured. I just bought the truck one week ago today and traveled 500 miles when it broke down.
Thank you again

Thank you for your response. Please let me know how things go at the dealer. If you would like to email me directly with the information when you get it, I would be happy to look into this. You can also find the VIN on any insurance papers you may have. Thanks!

Christina, I sent you a couple responses thru E-mail, the problem is the injector pump. The truck won't be finished by today at all........

Now the dealership says that the crank is broke. They replaced the injector pump and the truck didn't start. The problem we have is that if the crank was broken the motor would have a lot of different noises to it when it was turning over and when we were on the side of the road there were no other different noises. I believe the dealer doesn't know what the hell they are doing (in my opinion)..... It would be nice if someone from GM would call me on this matter............
#394 of 421 Silverado starting problems
Nov 28, 2011 (5:38 pm)
I have a 1998 Silverado with a 5.7 liter engine. I recently did a full tune-up on it to include spark plugs, ignition wires, distributor cap and rotor.The problem is the truck runs fine until it warms up,then the truck is hard to start and you have to hold the accelerator to the floor before it starts and sometimes it runs rough like it's running rich. It's not showing any trouble codes on my scan tool. I did a resistance check on the temp sensor and it's within tolerance according to my service manual and there is the correct voltage going to the temp sensor. Have changed the knock sensor too. I haven't been able to diagnose what is causing this. Any helpwould be greatly appreciated and thanks in advance

Did you get the plug wires on snug?
and have you checked the mass air flow sensor? It should be on the 3-4" tube that connects from the air box to the intake(?) and look like a plastic credit card holder sticking off the side. Do a 'tap' test when you start it from cold and see if it cuts out. This killed me in diagnostic time on a couple GMs the first time I encountered a bad one. They have a tendancy to cut out only when hot. If you were inthe air filter box you could have flexed, cracked, unplugged the sensor.
