[Shotimes] Cam Position Sensor, How long to replace?

[Bruce Malachuk]

How long should it take to replace my cam position sensor? I'm having some
wierd strting issues and I have ruled out it being a failed fuel pump check
valve. From what I gathered from some ppl, when that parts fails or acts up,
the car will just guess when to fire the spark on startup till it gets one
right, It has acted up a few times in the past but never to this extent.

Anyone have a rough estimate on replacement time?

Thanks
