Vehicle: 1997 4x2 Ford F-150, 4.2, 6 Cylinder, 110K miles, Recent (1 week ago) oil change, brand new battery. Overall condition is very good considering age.
Problem: The air temperature was about 5 degrees & my truck would not start. When I turned the key there was no engine response or “dead battery clicking sound”; the battery was only 1 week old. I confirmed battery power (headlights, radio, wipers) all checked out. Adjusted steering column automatic transmission shifter in a few positions (drive, neutral reverse), reinserted key, still no response from the engine. Two days latter air temperature was about 35 degrees & bright sun, turned key, engine briefly (1-2 seconds) had a “didn’t want to start sound”, heard one loud “pop” or “backfire” sound from under the engine hood (I didn’t notice any black or blue smoke from exhaust pipe) and then the engine turned over and ran normally. Ran the truck for 15 mins and has since been working fine.
Could this have been any of the following: frozen fuel line, fuel injector, starter, alternator, etc.? Should I use dry gas when temperature becomes “arctic?” I have been hearing varying answers and right/wrong types of dry gas. Also varying opinions on types of dry gas to use.
