What would be the chances for a crank sensor to have good operation 99% of the time, and fail only occasionally? Could it be possible that a failing crank sensor, or bad alignment of a crank sensor cause engine to run fine, except for under boost >10psi ?
I thought my valve springs were soft, but just before I took off the covers I started to have lack of Crank signal on FAST unit. (Looking at LEDs)
I do have CAM signal during this no-start condition. If I wait a while the car then starts fine.
I briefly worked with Cal Hartline and One other local Guru at Dyno. We changed the Coil pack and plugs.
Right at 4900rpms or so, and just making some boost.....the car just kinda fell over and stopped making any more rpms and power.
Sounds fine from outside the engine...?
Do crank sensors for Buicks, and I guess Hall-effect sensors in general, have this behavior of working then not-working like this?
Thanks
