I have an 06 excision with no start issues. Scanned it and had a crank sensor fault replaced the sensor and still no start. Scanner reads same icp that the ECM is asking for. Oil level is good and clean. New fuel filters. Ficum module is working bc the injecters buzz with key turning on and it passes the buzz test. And the KOEO TEST it passes also. Fuel pressure is good. It spins over for 30 sec then acts like it try's to start and stumbles then goes back to just cracking. No other codes are present in the ECM. Mods are egr delete, sct programmer. Any help is greatly appreciated.
That is my next step is to disconnect the ipr to put it in default. Sorry about being cage with my last post just don't remember exact voltage is all.
Disconnect the ICP sensor, not the IPR valve.
Before doing that, check the ICP reading with just the key on and see what the voltage reads. Then crank the engine and see what it reads, along with the IPR.
Also, it is important to know the exact FICM voltage while cranking. A few volts can mean the difference in starting or not.
Holy Smokes, like the guys asked you need =
ICPV ( volts)
ICP ( pressure )
IPR ( percent)
FICM MP ( main power )
FICM LP ( logic power )
FICM VP ( vehicle power)
