I have a 1994 mazda truck with the 2.3l engine and a manual tranny, anyways when the truck is cold and I try to start it for the first time of the day it just cranks and cranks but never turns over almost like its out of gas, the fuel filter is new and so is the fuel pump relay switch the fuel pump is also new. the only way I can get it running is if a get someone the help me push start it, now heres the thing I cannot fugure out once the truck starts and it runs for a few minutes i can shut it off come back after a few hours and it starts right up, it only does it when the temperature is below 40 degrees.
