Fuel thermo sensor (not on the back of the gooseneck)
My friend has a Thermal sensor code (23) on his car. This is the sensor between secondary fuel injectors. I wonder if this will keep the car from running?

built my own engine
if i were an engineer, and the fuel thermosensor failed, i'd make it read - values, like the air/coolant temp does
and then that would make it ULTRA rich
and then that would make it ULTRA rich

Im not sure if that code throws its into limp mode or something but Id think that it wouldnt keep the car from running because I had my water and fuel thermosensor connectors switched for about 4 months. It did run much better after I figured it out though but was still extremely fast the wrong way. I wasnt getting any codes though just giving the computer wrong readings.

Anything's possible, who knows what that pesky stock ECU is up to. 
The fuel temp. sensor is there primarily to sense a hotstart condition, so it can compensate for vapor-lock. The FSM says this hotstart mode (fuel temp above 92f, coolant above 158f) cancels vacuum to the FPR and switches the fuel pump to highspeed during starting and for apprx. the next 90 sec. after starting.
Other than seeing the code, are you actually having trouble with the car?
