    Looking for suggestions...

    This morning in NW Florida it was a grueling 42° F; the truck took 4 times to start.

    This happened about this time last year, searched the forum and found the TSB-0166-19, Extended crank... Took it to the stealership, showed them the TSB, and they dropped the tank, replaced the fuel pump, reflashed ECU, etc... Started fine for a bit.

    A few months back, it started showing the same symptoms as last winter but it would always start. Earlier this month, with about the same temperature, the truck took four times to start. Brought it to the dealership, and they were unable to find anything wrong after it sat for several days there. They said it might be a leaking fuel injector but were unsure and also reflashed the ECU. This past month, the truck hasn't displayed any codes or had anything stored in the ECU like last year.

    My battery was replaced last March and still checks good through Advance Auto's tester. The truck starts fine when the engine is warm.

    Has anybody experienced something similar and been able to pinpoint what could be causing my truck not to start?

    Truck has 86,XXX miles on it.

    Sounds like a fuel pump problem.
