Most likely the cold start valve is the problem. If there is a fuel pump problem or dirty throttle body, it would not run like pa champ once it started.
There are 2 possible causes of this problem:
1- Coolant temperature sensor gives erratic resistance readings confusing the ECM. The cold start valve only activates when ECM gets signal from coolant temperature sensor at cranking. 2- If there is a signal to activate, but it didn't open since the cold start valve is bad. Check these out and replace them to address the problem. Good luck.

Have fuel pressure tested in both situations. I've seen fuel pumps quit once they get heated up, then when they cool, pump again. Perhaps try WD40 sprayed in to throttle body inlet when no start, and that will tell you if it's a fuel delivery problem. Just remove air cleaner intake hose at front of throttle body, and open throttle and spray for a second or 2 then try to start. If it fires up and runs for a second or 2, then it's a lack of fuel issue.

Might be a dirty IAC idle air control valve. When starting up and it is struggling to idle does the car have a tendency to cut out if for example you turn the front wheels or put a foot on the brakes. If so, this looks like an IAC problem. Generally the fix is very easy and just requires the IAC to unbolted from the throttle body and cleaned with carburettor choke cleaning spray and then wiped down with a cloth. Once cleaned like new check the IAC ports on the throttle body itself and clean these. Make sure that everything dries off, reassemble and that should be it

We have a 2006 Chevy Aveo and it is having a problem staying started throughout the day. We try to start it in the mornings and it spits and sputters trying to remain started but eventually stops. Once we...

Start with replacing the fuel filter. The Aveo fuel filter is located passenger-side rear, in front of the rear tire.

If there is no filter there, then the filter is a non serviceable filter and is integrated with the fuel sending unit. Your going to have to replace the fuel sending unit if the fuel pressure is slow, start with running fuel injector cleaner through the fuel system for the next few fill up's and hope that will clear up the issues your having.

The other thing to is that your IAC (idle air control) valve may be dirty and is stuck close, you can try cleaning it by spraying Throttle body cleaner through the throttle body, paying attention to the IAC passageway. A dirty of faulty EGR valve will also do the same thing.

Start with the simple and inspect to see if you do have a external fuel filter, and inspect the wire leads to the IAC, EGR and clean them with throttle body cleaner. Don't forget to run the fuel injector cleaner through your gas tank.

Thank you for using Fixya and good luck.

Try replacing the fuel filter and check the fuel pressure at the shredder valve. Low fuel pressure from a week fuel pump or dirty fuel filter will cause hard starts, a bad ground will also do the same thing so check the ground wire for the fuel pump which is separate from the main wire harness to the fuel pump sending unit.

Good luck and thank you for using FIxya.

93 gmc safari 4.3 W engine code on long trips (25) miles the van will not idle and you have to pump the gas to start it but once it cools down and in town short trips it runs fine any ideas ?

The fuel pressure regulator is dumping raw fuel into the engine or the EGR valve is stuck open. Check for a fault code 32 (EGR) and test the fuel pressure for a stable or constant reading. ( Not dropping)

Problem with idle

Check your Idle air control (IAC) valve wire leads. It's located on the throttle body, the other thing to is it may be dirty and will need to be cleaned with throttle body cleaner. That is just simple cleaning out the throttle body through out, paying attention to the IAC passage way in the throttle body intake. Once you cleaned out the carbon that should help your idle problem, the other thing that would cause this a dirty EGR valve and it's stuck. The EGR can also be cleaned with Throttle body cleaner by removing it and reinstalling it once all the carbon has been cleaned out. replacing the fuel filter also would not help and that is located in the inside frame rail under the drivers side and takes about 20 min to replace. Start with the simple and replace the fuel filter and clean and inspect the IAC at the throttle body. Good luck and keep me posted.

Good chance that the idle Air Control (IAC) valve is dirty with carbon and needs to be cleaned. You can clean it by cleaning the in side of the throttle body with Throttle body cleaner (follow the instructions on the can), you can pick up a can at any parts store like Auto Zone. Disconnect the air intake tube from the Throttle body and spray the cleaner throughout the throttle body, make sue your clean the throttle blade and IAC passage way. Once your done with cleaning the throttle body and IAC passage way, just make sure you spray enough through the IAC passage way to ensure you get the IAC cleaned also. Once everything is cleaned, put everything back together and turn the ignition to the run position for 30 seconds and then turn it off for 10 seconds and then start the car, this will reset the IAC and if there is lots of smoke coming from the tail pipe. That.s normal, it's just residual cleaner and carbon burning off and will take no more then 10 min. This should clear up the problem, but check the wire leads to the IAC on the side of the throttle body for any damages like corrosion and after cleaning the IAC problem is still there. The IAC will need to be replaced, but i don't think so, since you did not mentioned any check engine lights on. Good luck and keep me posted, be glad to know your car is running 100% again soon.
