Its quite cold out and my car has sat for 2 months in the cold and the gas is from november. And I just put a pcm in from my 99 into this as I swapped its engine into my 2000. What do you think is wrong? It will crank slowly even when you boost the battery but just will not start. It crank slow. I have another battery that is charged and has been kept inside. Should I just use that battery? Please someone help. I'm ready to give up..
