1991 geo tracker doesn't usually start in colder weather.

[wildfire]

thanks fixkick for the all the diagrams etc....I already switched the relays before, and they were okay.
I cleaned up the connectors and ground wire behind the tail light...they were pretty clean.
I have tapped the gas tank before when it wouldn't start while my wife turned the key on, and it would start to sputter sometimes, and sometimes not.
Since it is a fairly new pump, I think your suspicion that the wires or connectors may be bad is correct, but it will be hard to detect which ones while the car is still starting.
