Well the issue is still there, after i have run the truck for a while it starts strong and fast. After sitting a few hours, (8-10 hours) it turns slower. I have already been though one FICM and dont want to replace another one. Any ideas or test's to run for draw while the truck is not running? Thanks.
theres your problem, throw those things in the scrap pile and get two new interstates or motorcraft batteries
(i went through 2 optimas in my 88 toyota pick up within 8 months and 1 in my 92 camaro within a year, i will never buy another one)
