2002 ford sport track. vehicle has been running fine. last week turning the ignition to the on position i noticed that i did not hear the fuel pump prime. I turned the key to the start position but, it would only crank. pulled the key out & turned it again to the on position, the fuel pump primed. cranked the motor & it started ok. been driving ok!
I drove the car to work & home last night, every thing ok. Went to start it today, i turned the key to the on position did not hear the fuel pump prime. I cranked the engine but would not start, tried several times, not even a sputter. shot some starting fluid into the intake, still would only crank, not even a sputter.. no smell of flooding. i did not check for spark yet. the outside weather is a high of +10.
last week the weather was also cold on the day that I first had a problem. Thinking about the fuel pump relay? or the securilock antitheft. I did try a spare key, no luck!
Thanks, Al

Thanks for the quick response.
My Luck.. I pushed the vehicle into the heated garage. The next day, I cranked the vehicle over & had my fingers on the fuel pump relay. I felt the relay click & heard the fuel pump prime. The vehicle started! Go Figure!!
I pulled the relay out of the fuse block & noticed that the prongs had some white powder on them, is it possible that the prongs were not making contact? I cleaned the prongs off & put some wire contact grease on them. The vehicle starts fine & runs good. I have not done a fuel pump preasure test yet. Kind of worry about the vehicle not starting again! Any other checks that I can do?
I did check the fuse block, two hot probes, I did not use a multi tester at this time.
I did use a code reader, no codes!
Thanks, Al.

the white stuff is corrosion and it will most definetly cause the vehicle to not have connection with the relay. when it was cold out the battery is weak probalby just enough to push it bellow the thresh hold and cause the relay to not have enough power to do anything. i would suggest carrying a spare fuel pump relay because the one may have moisture in it.
