My 2001 takes 10 seconds to start

[greensilver]

Every time I get in, after its been sitting for awhile, I have to crank the starter for about 10 seconds before it gets gas and turns over. Once started, I can shut it off, re-crank it and it starts instantly.

Runs great, lots of power, not temperature dependant, just seems to be short on gas, initialy.

Anyone have a clue for me here? If it's a problem with the injectors, is it something a modestly-inclined do it yourselfer should attempt?

Thanks.

Check the fuel pressure regulator. I believe it's a brass can on the passenger side of intake. It will have a rubber hose going into it. Pull the hose and if is wet with gas the regulator is bad. Seems to be a common problem.

You never said how many miles are on the truck but Dale fan sounds like he could be on the right track. But, check your fuel filter too. It could be something that simple.

Thanks for the replies.

I did some digging under my hood, looking for the pressure regulator. Didnt find anything that looked like brass or a can. I traced the fuel line up from the filter (mounted along driverside under chassis). The fuel line got up to the top of the intake manifold and metup with a very small grey, plastic valve-like structure. From the output of this valve, the fuel dumped into this tube-like manifold that distributed gas to all 8 injectors.

Anyhow, is this very small grey structure the regulator? I was expecting something brass or at least metal. Anyone familiar with the fuel pressure regulator on a 2001 Silverado 2500 V8?

Thanks!

More than likely not the fuel pressure regulator if it starts fine when warmed up, If I had to guess I would say check fuel filter.

I just changed the fuel filter. Didnt make any difference. Thanks for the suggestion though.

I'd have your fuel pressure checked,fuel pump might be getting weak

[knight60626]

Fuel Pump not a bad suggestion. A thing to remember about the in tank fuel pumps is NEVER let them get down low they overheat and weaken the pump. I have had to tow the same guy 3 times in the past year just because he runs his tank down to empty all the time, And it is always the same thing Bad fuel pump. BTW no it is not the pumps themselves as the Mechanic keeps putting in Fuel pumps from GM new sock the whole thing. I always consider myself empty when I get to a 1/4 tank.

Year,make,model and engine size go a long way in getting the right information.
How long does it have to sit before the problem occurs?
You want to check fuel pressure and see if it is bleeding down or if there is no pressure when you turn the key and have to wait for oil pressure to build up to activate the pump

I pulled the vacuum(?) hose off the reg and found no gas. Tried after running engine, still no gas. I pulled the reg out of the fuel distr. pipe, out of curiosity and now suspect sealing-gasket to be too loose. Somehow, I am loosing pressure. I read some threads on Chevytalk and found a cheap source for new reg. I'll put it in and let you all know what I found. Hopefully all those hundreds of times I filled up on a dry tank didnt kill the pump!

It was the fuel pump. Not the pressure reg., not the filter, the fuel pump. Cost me $800 to have it diagnosed and repaired.

Lesson learned, do not run the truck with a dry tank. It kills the pump.
