'06 no start appear to have ICP, ficm V/sync
I've read though the " no start" sticky and I cannot seem to figure my no start out. 2mo's ago my wife broke my starter, literally broke the housing and the starter was dangling. My neighbor ( a mechanic) put one on in my absence. He noted the alternator did have good output. Also before I left, I was getting a cyl6 contribution code, which in the past has meant its time for another dose of revX and historically that has resolved it. I changed the oil and put in ArchOil. I ordered an alternator and the next month I was out of town working, the alternator went out, She reported that the gauges when all haywire. Obviously the battery V was low for that to happen.
And then the rough running and eventual no start began.
My first thought was the FICM, but I have removed the inspection plate and measured it (47.5-48.5V) steady during starting.
Note: during a long crank I am getting black smoke between 5-10s, none between 0-5s, and you can tell it's trying to start. Also note, I have FICM sync.
I have attached my strip chart during a crank - no start attempt. No the IPR voltage doesn't perfectly line up with the ICP, and I'm beginning to wonder if I should be looking there, or maybe the the FICM is faulting - I do notice that the injector buzzing is less loud and to my recollection less frequent, if that make sense.
As of yesterday, there are no DTC's present and I changed the lower fuel filter and pulled the top to verify fuel was being pumped into the bowl. I have not checked fuel pressure, my gauge is for carbs (10psi)
Any help is appreciated.
