No start after ARPs and HG
I installed new oem head gaskets and ARP studs on my truck. At my first attempt to start I heard a weird starter noise, like it was low on compression. Come to find out i broke a rocker arm and bent a pushrod on the number 5 cylinder. The truck would start this morning run for a few moments then die out, any attempt to push the throttle and the truck would cough and die. The starter seems to being making normal starting noises again but now the truck wont run at all. I unplugged the ICP sensor and the truck would now run, but then die out again. So i hooked up my AE and this is what i found.
FICM SYNC- No (cranking will not fire)
ICP is the same as ICP desired
IPR is at 15% until cranking then it jumps to 70-80%
FICM is at 47.50v
FICM pwr is at 11v
CKP and CMP sync (no, even though it switches to yes sometimes. It was doing this before i did my head gaskets.)
I took my truck to a local diesel shop before i decided to do the head gaskets myself to help figure out a misfiring problem. He hooked it up to his IDS and tried to run a relative compression test and it kept kicking him out for failing rpm. However his IDS did get a ficm sync during the test. He told me to try to put a CPS in and see if it helps and it didnt.
Fast forward to now. The truck will not fire off at all no matter how long i crank on it. Sometimes when i crank i can see the RPM gauge fall to zero while the motor is still being spun over. I am getting crank and cam position codes like crazy. Is it time for a new crank sensor or is something else wrong? When the truck was running is was pouring out white smoke but when it died it would puff out some black smoke toward then end and it all smelled like fuel.
