FUEL

1992 Chevrolet Blazer • 120,000 miles

Turns over fine but only starts when I use starting fluid then dies I thought it was the fuel pump but I put a new one in. Its getting gas all the way to a fuel pressure valve on the manifold area after that not sure what to do plus I couldn't here the pump intel I replace it.

Have you checked the actual fuel pressure yet?ALso have you checked to see if you have battery voltage to the injectors with the key in the run position?ALso the other wire to the injectors should be a pulsing ground while cranking?

What large connector might u be talking about the release valve or what no I have not checked the pressure yet I hoped it would not come to that .

Iam trying to figure out if you have the fuel injectors inside the intake manifold which would have a large connector on top of the intake manifold. Or can you see each fuel injector with each connector going to it?We have a fuel problem so checking the pressure would be a good idea and is pretty easy to do. Any codes in the computer?

I dont have a code reader for this year mine only works on 1996 & newer I will look and see about the injector plugs and I have to rent a pressure tester.

It does have the plug on the top for the injectors today I put a new fuel pressure regulator even a new oil sending unit on and still the same problem.
