Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Justanswer. Thank you for your question and I will assist you with your concern.If you install your fuel pressure gauge to the fuel system what is the fuel pressure reading when the engine stalls out?
Are you able to keep the engine running if you give it some fuel when placing it in gear?Can you rev the engine in Park?
The fuel pressure looks fine but it sure sounds like you starving for fuel or the engine can not breath, are you sure the exhaust system is clear?
Well this sure sound like your loosing fuel pressure but with everything you have replaced I am out of ideas. I will open the post back up for you and perhaps another has something different to offer.
Hello, have you checked the fuel presure regulator?
how were the fuel injectors cleaned? did you see the spray patern out of them?
it doesnt take much to plug up an injector.
if you have a bunch of dirt in the lines and you had to flush out the lines, than bench cleaning with brake clean will not clean them properly.
injectors sitting around for 8 years with raw old fuel will ruin them and have low flow.
right now im pointing to your injectors as being the problem
flow testing them while energizing them is the only way to check the flow.
i honestly dont think brake clean will clean them. they have to be sent away for that.
i would pull the entire fuel rail assembly off, disable the spark and crank the engine and see if your spray pattern is good
i have had lots of cars that sit for a long time. and it always seems to be the injectors. injectors plug and fail so easily, especially on older gms. i would really see if you can have them flow tested
