Looks like your going to need to inspect the crank wheel... 😢

Not sure if you can see enough through the sensor hole with a mirror. I suspect it has damaged teeth or out of spec on run out.

 

Sad faces indeed

 

New EBCM is here, computers are all happy with life, dash no longer looks like a Griswald Christmas decoration

still on 4 cyl. Still starting with all 8 injectors and dropping 2. No spark on 5 and 8 still

looks like I'll need to get the car in the air enough to drop the front cradle and lower the pan. She needs an oil change anyway

what a bummer

Ok team, after a year and some change of the C5 sitting in my garage looking sad, I finally decided to tear into it

Before even touching the car I bought:
Billet reluctor wheel
Reluctor wheel tool
Lower end gaskets

Tore into the car and swapped a known good crank sensor into the car, started it: same issue. No fuel 1 and 6, no spark 5 and 8. Said "whelp I am prepared for the worst anyway"

18hrs of turning wrenches, shuffling engine stands and getting the bottom open later..... RELUCTOR WHEEL IS BENT

I see differing specs online stating .015-.020 allowable lateral runout. Doesn't matter, I have a total included runout (2 bends opposite directions) of .058"

From what I can see, the wheel is welded to itself, but not to the crank; so popping it off shouldn't be a huge effort

 

Heat it up with map gas and it will fall off

 

I'll update in a few hours when I have the wheel off

 

Hurry up!!! It's only been a year and half....

 

Old trigger is off

Crank is in the freezer, new wheel is in the pizza maker

 

After spending all that time and money the first time, finding out I had to do it all again really chapped me. I needed time to heal
