Thanks
It's a 4.3L 2wd with plenty of miles but very well taken care of mechanically (thus far). Very basic, no alarm, central door locks and such, so its not a security shut-off issue.
Here's a run-down of things I tried:
- Fuel pump makes ticking noise when priming, wasn't sure if that's what it's supposed to sound like so i tried starting fluid and still nothing. Checked the valve on the fuel rail while priming and there's pressure.
- Wires and plugs are a few months old so I ruled that out.
- replaced distributor cap and rotor (both looked pretty bad) but that didn't solve the problem either.
- there's about 1/4 tank of gas, put in a bottle of water remover yesterday just in case, still nothing.
I'm a decent "backyard mechanic" and do a lot on my own cars, but obviously I suck at diagnosing anything past the obvious. Any help/suggestion is greatly appreciated since it's a bit tight financially for me to pay for towing and the shop.
I didn't think that the 2001 had a cap and rotor.
1999-2002 CK1(03-53) ENGINE ASM-4.3L V6
Just a thought to those who can't seem to find the problem. He also took his truck to the dealer and I'm sure the idiots should realize there is a problem however if no codes come up on their computer they are almost useless.
Maybe this will help some, the symptoms all appear to be the same, erratic starts for no reason, fully charged battery, no clicking from the starter at all.
A week later, this past week, it occurred again. I asked the dealer/service manager if I could pickup a mechanic and bring them to the vehicle to conduct testing to avoid towing which they did. The mechanic determined the solenoid was sticking which accounted for no codes as power was reaching the starter, but the solenoid would not move. He indicated sometimes lightly tapping the solenoid with a hammer would loosen/unfreeze it, of course this would only be useful to get you into a shop for repair.
In summary, the irractic sticking of the solenoid was the problem which was resolved with an aftermarket starter installed by the dealership for $244. This to me was very acceptable as the vehichle had ~100K miles when the starter was acting up which I would not consider as an unreasonable lifespan for a starter.
Nice to have a good dealership to work with also.

I have had starting problems in past and I took the P/U to my mechanic. They told me that the crank sensor for the timing was the problem.I again after just 1 1/2 years have the same issue. I don't want to keep going to the shop when this issue arrises. Now the check engine light comes on "service engine soon", and the engine is running rough. The last time it did this the truck just over night did not start. I have always done the maintence repairs and fuel pump issues but now I want to handle this issue.
My question if any one knows is what and where is the crank sensor and I looked in my Hayes repair book and could not find it. That was strange. Does this part excist or did my mechinc rip me off?
Thanks,

2003 Silerado w/ 60,K miles.
When cold would crank, but not start. Yet when warm I had no problem. Checked many things. I finally replaced the fuel pump. This took care of my problem and I have put another 5000 miles on it.
I had 2 choices, drop the fuell tank or remove the bed.
I removed the bed as I do not have a vehicle lift. A dozen bolts, a few wires, and 4 people with strong backs and weak minds ( a 12 pack of COLD BEER helped :P )
I hope this helps someone.
You offer to provide assistance, but I have yet to see your resolution posted.

What I thought was the fuel pump is bad, already replace 5 of them but that is another story. Towed to a local mechanic and check fuel pump pressure and had 65 lbs. Did a scan and no codes were found. It sat there for 3 days and they couldn't fix it. Hauled home and call brother in law, who is a mechanic, just hate to always call him to fix, family you know. He gets here and it starts but some black smokes come out the tail pipe. He puts a gauge on the fuel line to see if it is holding pressure at the injectors and it has 60 lbs while running but as soon as you turn in off if leaks down to about 15 lbs in a matter of seconds. He thinks the fuel injector assembly is bad, the spider tubes is what he called it, may be bad and one or more may be leaking. Tear a part and all tubes look good. It will still start if you pump the pedal and crank for while but runs rough and then smooths out. Afraid to drive, can't afford the tow bill.
So what's up?

I need some help with a problem I have had for a few months now. I have a 2003 GMC Sierra 1500hd 6.0L pick up with 86,000 miles and it will not start the first turn over. If I then proceed to try again it will start either the second or the third time. If I have driven it recently it usually starts up the first time. I replaced the fuel pressure regulator and that did not help the problem. I noticed if I turn the key from the on and off position quickly 5 or so times, it starts right away. It seems I am not getting the fuel into the motor right away, is this the fuel pump? Fuel filter?
Any help would be appreciated.
I am wondering if its the Fuel Pump? However that is a expensive and difficult part to "guess" at.
I am wondering if you figured this out for yourself? Any ANY ANY help would be great! lol
Can you find an auto parts store in your area that can bench test your ECM? If so take it in to test. If not go to a auto wrecker and buy a used one to try out first. If it works buy a new one later on. You don't know how long the used one will last.
