truck won't start

[J17HENRY]

just finished my s475 over stock twins and deleating the factory fuel filter. now truck won't start and has pcm u 1800 code. any ideas?

U1800 is caused by loss of communication between the ECM and FICM. Check your INJ B 25A fuse which powers the FICM. If ok, check power and ground circuits at FICM
