    Extended crank but no start issue

    Ok had the reflash completed on my truck on Friday/Yesterday 11/5/21 (8600miles.) time will tell? What I have noticed already is the normal crank time.

    Engine No Start TechLink bulletin

    I have my fingers crossed and make much more sense now than a shim-in sensor, something at times is a corruption signal. We will see? time will tell, I need to schedule my truck to have reflashed, I have encountered the Crank No Start about 1 time every thousand miles, 7700 miles on my truck...

So Boos Auto had them on special and it was an easy install that works well, but the...

    New truck not starting

    Up to 6 times now. I just turned 6200 miles and it happened to me for the first time today on a cold start from sitting overnight? 5 other times it was on a restart after about a 5 to 30 min a hot soak and then crank no start. Almost like clockwork every 1000 miles it happens
