Chevrolet Work Truck Failure

Colleagues, I acquired a C1500 V6 4.3 truck of 97, it was stopped a while ago, the problem is that it does not start in cold, I must throw it to give the game and already use it in the day there is no problem, but they spend a few hours stopped and again it does not part ...
detect that it had disconnected a sensor that seems like a TPS or acceleration sensor, when I connect it and accelerate in depth the vehicle is stop I leave the vehicle disconnected does not stop. Will this be related to the fact that it does not start in the morning?

Thanks in advance ...

It may be that you are reading any wrong or this raid also reviews the acceleration body or the step of the minimum that can also be, the spark plugs as they are, also check the temperature sensor. The gasoline filter like this.-

Friend Frio's departure failure is due to the low pressure pump pressure you must change it for the original vehicle since engines 4.3 work with a approx of 95PSI. I spend days with that fault and it was the bomb.

That it does not start in cold it is possible that the temperature sensor is evil and is sending a false signal to the computer. What I do not know what sensor is that which had a cable outside the TPS has 3 cables and of course the engine would not officially official or stop or not regular
