the truck has been trowing the cel for like 2 weeks now randomly. its po261 cylinder#5 injector circuit low. i've cleared it a couple of times and it will come back to other random injector circuit low cylinders. i'm leaning towards the ficm. does anyone else have any ideas on this
Nope should hold steady at 47-48 volts. If it drops to 20 that is most likely why its setting codes. Should be hard to start cold and maybe even run a little crappy cold. They can be repaired. I thought I heard on here that BulletProof is coming out with a FICM power supply soon.
