Sounds like the fuel pressure regulator is shutting the flow of gas causing the higher pressure. The pump is probably ok since it is delivering fuel pressure.

I have a 2006, and I was just advised that it is the EGR valve, which cost 624.24 to replace. It is not a warranty item. Do you have any knowlege if this is an ongoing problem.

You need to find out what psi the fuel pump is. You need to run a "low" psi pump. They usually run 2-5 psi. Then you need to buy a good fuel regulator (not the dial type, those are useless) and set it to 3 - 3.5 psi.

Having good fuel pressure is a plus (yours seems a bit high but I don't have specs) What you need to find out is if the injectors are opening and putting the fuel into the engine so it can work. Are the plugs wet with fuel or dry? Does it fire up if you spray carb cleaner into the throttle body while cranking?

A practical alternative to replacing parts at random would be to take your vehicle in for a comprehensive diagnosis to identify the real cause of the problem(s).

Did you put a replacement injector assembly in under the upper intake, this is a major problem with this model. How's your fuel mileage? If this is your prob you need to change it because the leaking fuel goes down in your oil pan, thins the oil and blows your engine. Check your oil, is it over full or smell like gas?

Yea , those crossfire injection vettes can be a bear sometimes . I had dealings with them 84-85 - 86 working as a tech at a chevy dealer . Don't remember much about them , haven't heard anything about them for long time .

How's the fuel pressure ? Have you put a fuel gauge on it ? I would imagine you don't have a Tech 1 scan tool ? What's the map sensor voltage at idle ?

If your vehicle has one, and I think it does, check your EGR system. If the egr valve is full of carbon, it can be partially open, creating a vacuum leak. If the egr valve solenoid is bad, it could be opening the valve at the wrong time, also creating a vacuum leak. Unplug the egr vacuum hose, plug the open end of the hose and start it and see what it does. A picture of the egr is below.

You have a MAF and MAP, The mass air flow signal varies with engine load.It is attatched to throttle body. This if it is the primary signal can cause the problem you desribe try and disconnect it and see if it idles properly. The next item you need to inspect is the MAP ,manifold air pressure this is a back up for the MAF sensor.If this sensor fails you will not accelerate correctly and stall out flooding the vehicle with fuel. This monitor the MAF and your EGR. If the EGR valve is stuck open the vehicle stumble and stall out and affect the performance of the MAF and MAP.Make sure your MAP is connected and the vacuum hose is attatch this item is located at top rear engine compartment near fuel injectors

Car idels fine. stalls when you give it gas. changed o2 sensor, tp sensor, map sensor, and iac sensor. fuel pump and filter are new also. no vacume leaks. any ideas?


Items you should check are the EGR valve, unplug the electrial connector, which will disable it and see what happens. The other is the fuel pressure regulator, the best way is a pressure gage. You can also do a basic check by finding the RETURN line and crimp the rubber part closed with a suitable tool that won't damage it [ a pair of needle nose visegrips with some fuel line over the prongs works ], If it takes gas- then the regulator is faulty and needs to be replaced.
