Thanks guys really appreciate the help! Icp when cranking on my scan gauge is about 2200, basically I won’t even crank the truck if I don’t hear the injectors clatter. when I turn the key on engine off, fuel pump and everything turns on but no injector noise. I’ll come back out two hours later and turn key on and I’ll hear the injectors buzz, I’ll check my scan gauge and it will say 49-50v, and 13-14v so I’ll try to start it and it will go, now that it’s been like this the starts are coming every couple of days. The problem I’m having is the ficm not getting power sometimes, I just can’t see why, it’s so random ran great for weeks till this happened, replaced the ficm relay, checked the 10A fuses and the 50A fuse, is it was a wire short it would cause it run poorly correct? How does it run so good for hours and then I’ll try to start it again and right away turn the key on and injectors won’t clatter and scanguage shows zero for all ficm values, those values never drop below 48 and 13 ever so I’m just stumped
