cps: OBS same as SD??
Just wondering if the cps is the same from OBS to SD 7.3's. A buddy's been having starting troubles and now she cranks but no start and no tach movement. I lent him my spare, but he hasn't had a chance to try it yet. Just thought I'd ask.
Thanks

They show different part numbers but the same prices and manufactures, I beleive they are the same with the exception of the timing mark indicator is in a different position. Therefore it might not bolt in right but could be used for test purposes.

There is a metal piece attacched to the cps that is the timing mark pointer, used in showing the timing on the harmonic balancer just like a gas engine. However unlike a gas engine there is no physical timing adjustment, its all done by the PCM. So assuming you had a computer to link the truck to tell the pcm to adjust the timing, you could take a timing light and verify that it is firing at the proper degree.
