My 2007 F250 6.0 has 86k miles. Amsoil oil Bypass kit and coolant filtration kit, Deleted EGR Cooler and have an SCT X4. I parked it last night after work and returned it back to stock settings because I was going to reinstall my banks 6 gun with IQ for better monitoring now this morning it wont start. Cranked for 15-20 seconds to make sure oil pressure was on the gauge and there was. Disconnected IPC and no start. I checked for codes on the Banks IQ and nothing was coming up, I updated the firmware on the Banks kit just to see if it was an issue and still no start. Cranks for days, no smoke at all. Maybe the IPR? Any help or advice is greatly appreciated, its my DD. Thanks.

 

Just Checked FICM. Key on 48 Volts. Cranking 46Volts. looks like that's operating normal.... Where should I go next?

 

Just replaced IPR. Still no start. Sputtered for a split second. Now nothing.

 

Load your sct tune back up and see?
