Starting Issues My suburban will not start when it's cold outside, it will crank over but will not fire. If I wait for the temperature to come up, the truck will fire up on the first try. I have tried cycling the truck, yet it still wont start. This morning at about 5am I tried to start it, no luck. At about 10am I went out and the truck fired right up like nothing was wrong. I dont have stalling issues or lack of power issues, just this flippin cold start issue. Any help is greatly appreciated. Thanks.

SOURCE: Truck has trouble starting- runs fine after start

I found the fuel pressure regulator on the fuel rail was leaking fuel into the intake manifold via the vacuum hose.Was hard to start and rough idle. Pull vacuum line and see if fuel is coming out-if so like me-replace it. About 50.00 at Murrays. Also the two inner cylinders on the passenger side-opposite of the vacuum line will be very rich fouled-replace them all

A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech

Did you try to get any DTC codes from the ECM. If not here is the procedure to retrieving the DTC codes. http://www.troublecodes.net/GM/ Check the fuses, make sure there all good. hope you find a DTC code which would help us find out what is wrong with the suburban quicker. Keep me posted and good luck, be glad to help you.

Try cycling the ignition on and off three times, Turn the ignition to the run till the check engine light turns off on the dash and then turn it off and do it again three times to pressurize the fuel line. Then start it, your fuel filter may be dirt or the fuel check valve at the fuel pump may be bad making you loose your fuel prime. Start with replacing the fuel filter first and let me know if that helps and let me know if cycling the ignition to pressurize the fuel line helped.

Let me tell you the truth, its your fuel pump. everybody tells you to check youre injectors and replace youre fuel filter but the truth is its your pump. all chevy and gmc models have that problem. I just replaced mine. i have a 2001 chevy 2500hd also with the 6.0 and did the exact same thing. I bought a fuel pump and put it in and BINGO truck runs and starts like new. TRUST ME MAN
