2005 Silverado Duramax. Last month in Waco I lost throttle at a gas station. towed to Chevy Dealer, who replaced EGR Valve. Been runing fine since. Today in Edinburg, the check engine light came on again, running fine, no immediate concern, so I kept driving another 50 miles ot hotel. Shut it off, now it will not start. Rapid fires when attempt to start. Any ideas would be appreciated?
Broke down today

Don't know what that is Rapid Fires--??
Welcome to the Forum-- the Check Engine Light will store a code in the ECM, and that points to a place to look for the problem. Without the code-- all anyone can do is guess.
Check this first--On the passenger side of the alternator, you will find the FICM wire harness-- it is tied down with a Zip tie--- cut the zip and pull the wires from the wire harness-- inspect carefully for cuts and bare wires. The sharp corner of the bracket it is tied down to, cuts into the wires and causes shorts. This may not always throw a code.
Insulate with a piece of heater hose, to prevent further problems.
Common problem for a 4.5-- 5 LLY engine. Everyone with a LLY engine should do this easy fix NOW!
Pump the primer button on top of the fuel filter housing, does it get firm-? Does it start-?
Check these and report back.

Priming worked
Well Hallelujah, I primed the fuel filter pump and it starts and runs fine. When I shut it off thought I have to manually prime it each time. I am 280 miles from my home mechanic and do not go home until Wednesday. I might just prime it manually until I get it home. Anything wrong with that appraoch? I don't want to get stranded on 281 on the way north.

Leaks
When the EGR Valve failed last month in Waco, The Chevrolet Dealer replaced it, and also replaced the fuel filter. When I went to prime the button I did not see any leaks or smell any diesel. I was driving 70mph coming south from San Antonio and got about 60 miles north of Edinburg, felt the truck like it was hit by a gust of wind, at looked down and the engine light came on. I think it must have lost power for a split second or something because there was no wind at the time. I just kept driving with fingers crossed as everything else looked good. I had just filled up at teh Valero in Premont about 10 miles back. Maybe I got some bad diesel, but it is running okay once it starts. It was after I shut it off at the hotel this all began. I think I will drive it over to AutoZone tomorrow and ask them to check the codes now that it is running when manually primed. You all have been a huge help.

Codes
A heavy truck diesel mechanic scanned it today at the jobsite I was working at and he said it was P0340 and P0341, camshaft position sensor. My mechanic in San Antonio said he does 1 Chevy camshaft position sensor for every 50 Fords he does it for, and cannot believe it. I had it towed to a Chevy dealer who is going to diagnose it in the morning. I drive only extremely well maintained vehicles, and in 25+ years cannot remember being stranded by a vehilce on the road. This diesel has had to be towed while I was out on the road twice since I bought it in March this year. Not liking my duramax diesel at this point. I bought used instead of new due to the economy, and everyone and all research said this would be a good vehicle, 250,000 mile engine cycle blah, blah. One more time, and its going to auction. Sorry little beast.

I hate to hear that man. Before I got mine, I researched like crazy and all signs pointed to these being the most reliable... by a long shot. But all that means nothing if the one your driving is broke. Hopefully this is the last of your troubles for a while.
PS... that part of TX is not a fun place to be stranded. It's a long way from anywhere.
