In terms of Aftermarket , only BD foglights that have been installed years ago. No tuners or performance add ons...etc
Regarding battery test, used a battery tester/analyzer at home "Foxwell" without disconnecting the battery.
It showed good voltage and around 820CCA.
What happens after turning the ignition on and after all warnings appear on dash, whenever I try to start the only thing i hear is a one-click sound that comes from the passenger side probably from the fuse box.
And as we all know, whenever the truck is unlocked the fuel pump gets primed but in my case it won't.
