Help! 2006 6.0 king ranch 189k sct live wire Replaced 1357 injectors and when I crank truck it will crank and sputter for a brief second but will not fully start and continue cranking and doing this over and over. Tried starting for roughly 30 minutes would not budge. Tested icp and ficm both are good. Also replaced batteries, fuel filters, checked all relays and fuses still can't figure it out. Also truck is bulletproofed. Need some help! Thanks

 

Do you have FICM syn?
Be sure the harness for that side is seated in the FICM good and proper.
Fuel pump runs like normal? Upper bowl fills up straight away if the key is turned on?
Injector clatter is there before you try to crank it?

Be sure to give the starter time to cool down in between periods of cranking or it will burn out.

 

How do you check sync? But yes everything else good can hear injectors and bowl fills up

 

with a Scan Gauge or Torque Pro app... you need to see some live data to really see whats happening..... or we could just keep guessing.

 

Is it possible for my sct live wire ts tuner to read ficm sync?

 

Hi Austin -

Not to my knowledge, no. What's the latest on this issue for you?

 

Sounds to me like his ICP pressure isn't high enough... wondering how it was tested?
FICM plugged in and solidly connected, it is the entire bank.
