97 s10 blazer codes

I'll start from the beginning, 2 weeks ago I rebuild the tranny and put it back in the Blazer, prior to that the truck sat for about a year. I just came back from the store and the truck shut off 2 times on the way home, my speed at the time was about 80km. When I got home I pulled the codes and this is what I got P0131, P0507, P0337.
I'm going to also put the freeze frame here cause I can't make sense of the freeze frame.

STFT B1 is way high in freeze frame.
But that freeze frame at 177 degrees and at 16 MPH is not a good time to get a freeze frame.

Get a couple at 60-65 MPh steady driving on the road with good warm engine at 195 to 200 degrees.
And one at idle after a good long drive on road.

But first clear codes and see what one comes back first.
Also fuel pressure and fuel filter should be checked.
Low fuel pressure can throw off 02 sensor readings or fuel trim readings.

Watch that crank shaft sensor.
If code resets for it you have a wiring or sensor problem there.

Post back any codes thqt come back after code clear and your fuel pressure readings.

Codes show a crank shaft sensor problem and 02 sensor not reading good.

thank for your input but i can do anything with the blazer right now cause now i cant get it to start, when i turn the key on the radio and stuff will come on but none of the dash lights will come on and the gauges won't work and if i try to start it all it does is just crank over and over but it wont start.

Right now is a good time to test it out and fix it.

That no dash light stuff and no start problem is 99 percent ign switch problems.

97 is a bad year for ign switches.

If no dash lights and stuff coming on check all power feeds from ign switch.

Let us know how it goes.

97 has known issues with the ignition switch and it can cause several different and seemingly unrelated things to happen when it takes a crap. Might want to look into that as well as the things MT recommended.
