My Truck's engine cracking but no start!

I tried many times to start the truck but it doesnt start. Its just cranking.

I checked DTCs code. At first there were no code. But after many attempts to start the engine, one code comes up.

P0611 - FICM Performance

I cleared the DTC twice to get rid of it. But it appeared again sometimes.


Therefore, I removed the FICM Module & cleaned the three connectors then installed it after 10 Minutes. The engine started successfully for just 30 seconds :( then shutdown.

it works for 30 seconds if I remove it for 10 minutes then install it.

I tried installing a F350 FICM module (It dosnt have the same part number exactly), the engine starts for 30 seconds again the shutdown.

Im afraid of buying a new FICM Module for no avail.

P.S. I tried to reprogramming the FICM but no avail.
