could this be the reason I have had a problem? vehicle ran fine a month ago. cold winter, have not started it in this amount of time. turn key, see cel, cel goes out after a second, hear click up front, no fuel to the rail. replaced relay, replaced pump/sender unit, fuel filter. still nothing. clicked ignition on 3 times, codes were disconnect battery, a/c fault, and that was it. i shot starting fluid in the intake and got fire so it is a fuel prob. any ideas if this will work?
