Am I seeing a sign of impending fuel pump death (Regina single pump)? 900 1993

There is a temperature sensor in the block under the intake manifold. On my 740 it was between cylinders 2 and 3 I believe. When working properly its signal tells the ECU that it is cold and extra fuel needs to be injected - kind of like a choke. If the wiring is flaky, as it was in my 87, sometimes it will work , sometimes not.
