I am so bummed though; it seems that changing the regulator was fixing everyone elses issues and was hoping for the same.
Well I do think we worked all the bugs out this time...
it seems that even when the fuel relay had been removed from the truck, they noticed that the fuel pump continued to stay on......? so they began tracking the electrical wiring using a skematics to isolate the fuel components, and found a bundle of wiring that had melted when at some point it had crossed over the exhaust next to the engine block. the wires apparently were enclosed inside the plastic tubing commonly used to protect them, and when the two wires touched and bounced around it sent a current, and could not be seen. I got the truck back on friday, and over the weekend drove from colorado to visit my son in kansas and put 1,500 miles on it without any problems.
is it your fuel pump stays on thats the problem?... or a no start? fuel injected or carb? I have never heard of a fuel filter being in the gas tank before....(well, maybe?) usually on the front of the carb. or looks like a 2 or 3 inch cylinder attached at both ends within the flow of the fuel line, in the engine compartment, or can also be located just under the driver side door mounted on the frame within the fuel line. if you live in a cold snowy area like I do, we have lots of the no start issues with things freezing.. good luck with that... let me know ok, thanks.

Have you checked your timing?
Is your truck an automatic? ..if so ..when you put it in DRIVE, and without your foot on the gas, will the truck move by itself? If it does, turn your timing down.
Being that the truck runs fine once it's started, it hasn't been one of those hot issues I have been putting as much effort into as I should be....but we all know that these problems end up leaving you stranded one day. So far though, the truck has been doing this for about a year! I know that what I need to do is check voltage going into the fuel pump to see if it is getting the voltage to prime it and then keep it running when the truck is going. That would tell me if it is the pump that is suspect or the relay/other wiring, but I have just been reluctant to dive into it so far. I was hoping someone would have experienced the same problem at one point and maybe this is somewhat of a common problem.....but that does not seem to be the case.
I have a 79 firebird, does exactly the same thing... we just know that it will always start on the third try, we have just become accustomed to that always being the case because after it does start initially it runs beautifully, with the exception that it does have some compression issues. the timing is right on and has a recent tune up. my husband suggested that possibly you could check the connection from the sending unit (at the top of your gas tank) where it has a clip/plug connection to see if it has any rust developing inside there, and use an electrical grease inside the clip to prevent problems later on. for my firebird, I really think a sound solution is to start saving for that new motor in a couple of years, or have the top end rebuilt at some point on the motor we got, and for at least two years now, with regular maintenence covered, the cold start with the older engine has never been a huge problem for us, she has always started on the 3rd try.
I was wondering if you have made any progress on your hard start situation. One difference I notice you have from all the other is that you do not want to start on the FIRST try; theirs are all having trouble on warm starts. (Plus the flooding smell) Anyway, I ask because I am having the same problem you are. A friend of mine went through a similar situation with a different GM vehicle and it was the fuel pump. A very expensive job as well as the pump itself is around $600! Anyway, I am hoping maybe you have found a lower cost culprit!!!
Unfortunately I have not put much time into it....probably because I know the answer of how much it is going to cost and how much work to do it. I may get around to putting more time into it this weekend, but we'll see.
TAC (case #7952789). Replaced ignition switch assembly.
Recheck in a.m.--OK. I had this work done in Jan/05. The above info. is off my invoice of repair. I hope this helps many of
the posts I have read.
And don't even think about putting aftermarket exast on there, I did. It sounds great like it should in V8 mode, but when V4 mode kicks in all you can hear in the cab is loud backpressure, extremely annoying. IS there, or will there be a way to disable this menace called active fuel management???? :mad:
18.2 mpg is mighty impressive for a powerful full size pickup. I'll accept a split-second lag (and I mean 'split second') when accelerating from the V-4 mode to get that kind of mileage. However, the truck was in V-8 mode more often that V-4, so there is NO lag in that case.
When gas hits $4.00, and it will, and sooner than we all would like, no one will be whining about AFM.

It is interesting to compare our mileage to the new A380 Airbus. It holds 500 people, has a storage load of 70,000 lbs, flies 400 MPH and gets 10 miles to the gallon.
BTW, I think you meant the airbus gets 10 gallons to the mile.

Anyone have success with an aftermarket cap?
I have experienced NO jerking or noises. It is totally seemless on my 6.0L Silverado. Don't accept what the dealer says. Go back until they make it right. Or go to a different dealer. Take the chief mechanic on a ride.

Is it only the on board computer showing the instant fuel economy increase, or is there some other type of indicators?
thanks

I agree with the last guy that lifting the bed off is probably a lot easier than dropping the tank so I would suggest that if you had the option.
Now that thats out of the way, on to my problem:
My 2004 Chevy Silverado started acting like its out of gas this morning, and it keeps dying. I know its not out of gas (put $40 in this morning). I live in Las Vegas and we have had temperatures over 115 every day this week so I am not sure if this is a heat related problem.
It died the first time, started back up, chugged and pinged a little bit then died again. After letting it sit for 10 minutes it started up and went about 2 miles before it died again. I repeated this process 10 or 15 times until I was able to limp it home. I would imagine it is a fuel line/pump/thingamajig problem, but like I said I am a moron when it comes to cars so I have no idea what could actually be wrong. Any help would be appreciated.
In case it's important to know (which I dont know) I installed a new battery in this truck 3 days ago.
