i have a 2000 s10 blazer with the 4.3 vortec engine and i have replace the fuel pump, filter, fuel pressure regulator, throttle control module, and much more.
does anyone know if the icm or the ecm will shut down the fuel system if they are bad, checked the voltage on the fuse of ECM B and i get no voltage. when the blazer is cold it runs great but once it heats up it shuts down.
fuel pressure is 60 at start 50 at idle and holds at 50 when shut off. i know it is not a issue with the fuel system.

thanks in advance.

Does anyone have any ideal's what this proble could be with this model Blazer?

 

I am having problems with my blazer starting. I have changed fuel pump, fuel filter. And it will run a few day's and just cut off. I have taking it to several shop's and have had crank sensor replaced spider injector replaced swapped out fuel relay fuse. And now after 700 dollars later my truck is doing the same thing. Can anyone HELP ME!

 

Dude, you resurected a 2 year old post from the New Members Section, and then bumped yourself 3 times in less than 24 hours. You'd be way better off posting your question in a new thread in the correct section.

That being said, you should start with a leak down test (search if you don't know what this is), then post up your fuel pressure numbers in a new thread in the 2nd Gen and give us a good description of what your truck is doing. You'll get a better response there.

 

10-4 I will post my fuel pressure numbers tomorrow... Thanks for the aspirin
